The plasma spray has been used in industrial diesel engines for years. The company that invented it makes hand application units for doing main tunnels. There is also a deck resurface machine that can do over 20 thou of deck addition to save a big engine block. When the diesel engine is $1m you would rather keep rebuilding than buy new.
I've experienced seeing these types of liners during my factory training at BMW years ago with the Nikasil, and it also reminds me of the Honda B21a engine back in 1990 with the FRM (fiber reinforced metal) cylinders. Both were extremely smooth, definitely different looking to the naked eye, and almost no crosshatch at all. Oddly enough the Honda FRM would eat rings like crazy and you would have tons of oil consumption and black smoke once it got to a certain mileage, but I never did experience ring wear with the BMW's. Thanks for the detailed info about working with these liners. 👍👍
many years ago I worked for Textron , Homelite division. We used anodized aluminum for the bore and used a grit blast process to make the pits for oil retention. It worked.
Homelite? Do love my lil straight shaft weed Wacker that I just resurrected. I haven't needed it in a couple years, but now I do. Some fuel lines and an air filter and off it goes. I was shocked that almost no parts are available ,then I remembered it's 20+yrs old and not supposed to last that long. Hopefully it'll go another 20. Does this thing have a treated bore or it's just standard stuff?
This is a great video! I will watch your other video about SMEBore on your boxster engine next. I have a Lokasil engine in a Cayenne that has massive bore scoring. Seems like it might be a candidate for this process...
Greetings from Concord, NC! Thanks for this video. I’ve recently gotten into the hobby of rebuilding old Suzuki race motorcycles and knowing they have a NikaSil coating, this info will certainly serve me well down the road if I should ever have to do any cylinder work. It’s cool knowing how the Plasma spray bore coatings work. I’ve learned a TON from your channel and your videos!! -Josh
Awsome brother!!! I have been wondering about the the new 5.0 Coyote engines. I have been hearing about spray bore in the 5 liter and was thinking they may be disposable blocks. I guess not. Thank you for the info.
I have to believe the spray bore is a cost cutting measure only. Not only does it cut down production time and cost, but a damaged cylinder means the block is trash, where a standard liner can be honed deeper, bored, and replaced. Not to mention a nicasil liner is more rigid than just aluminum cylinder with a surface coating.
Thanks for posting. I learn stuff from your posts lake. Ive owned the total seal profilometer, computer since they first came out. I used to hone a bunch of spray bore coyotes 8-9 years ago and had a profilometer at that shop but wasn't doing them correctly after watching this lol.
Whats the longevity of this surface compared to current methods of honing that are being used and the difference in cost? The visual image in my head is the standard crosshatch doing better at containing a controlled amount of oil. Interesting process.
I read about the Ford 427 having such thin cylinder walls, the FSM says do not overbore. It was also said to be difficult to sleeve. Anybody ever save a cast iron engine that way? Sure, I read about people using such tech for alumnim engines. I wonder if it is a good move.
Not such a new material Sume Bore defines the use of other lubricants but only for this place of contact cylinder piston rings. Are there already such oils that take better care of this place and do not forget about other places in the engine where friction occurs?
So you can't really bore and rehone making say a coyote block a throw away with a small scratch ect? How much would it cost to overbore and re-apply? Does Total Seal have specific rings for plasma bore?
I'd like to see a test of a glass bead blasted cylinders with various types of piston ring material. Used cylinder bores . Instead of using dingle ball hone for clean up on a rebuild.
See Eagle ESP Armor or Isotropic finishing. Comes out looking like chrome. I wonder if then a part could be cryogenically treated to further change the metallurgy to make it hard.......the combo might make any part really bullet proof.
interesting to see the Porsche cyl Lake, but Harley sells hundreds of thousands of bikes in US alone. I think their cyls have a similar coating. Could you pls do a vid on them? thx.
Thanks Lake... great presentation: So, it would appear that the Plasma/Sumi bore cylinders wear incredibly well.... And hold oil at the same or better level than a deep RPK iron bore.... In the end, a superior bore in terms of wear, or at least it would seem. In search of better durability in builds for my customers where quality/durability is worth spending more on, using what is typically a "conventional V8 iron block", are there any pre-plasma-coated liners/sleeves that can be installed in a block... that is 0.010"+ undersized... and taken to size using the stepped honing method from rough to 1200-diamond to bring this tech and wear property to older iron (or aluminum blocks for that matter) @TotalSeal .
Just out of curiosity from watching these bore finishing videos, would it be right to think that if you a very smooth finish (1000 grit sand paper) its those valleys depths that are important to hold enough oil?wouldn't the rings aquaplaning if the surface is too smooth, how would the rings bed in? Dry or wet start up in a break in period?I came across some chromard liners from isuzu and they are very smooth,and they last ....
arnt rings moving on an oil film aquaplaning all the time. Basically instead of peaks and valleys it just valleys. Then there are not sharp peaks to cause wear or make the oil film less uniform.
Has anyone tried to finish a cast iron bore as smooth and then blast it with some abrasive medium to create oil retention, would be a lot more cost effective so much for the crosshatch everybody seems to believe is necessary for filing the rings in..
Metallography and looking at the structure of cast iron under a microscope are the beginnings, already at 400x magnification it starts to become clearer in our heads
Hey Lake, where or who does the plasma spray bore or Sumerbor coating application? Also, is there soneone close by who can hone it to the correct finish and any contacts would be appreciated?
The problem with the high tech coatings is cost. Stuff has gotten so expensive at machine shops that they are folding up and closing from a lack of people being able to afford their services. I know I never had a motorcycle cylinder replated they got a sleeve so they could be bored out several times.
How do we hone or clean up a cylinder that an aluminum piston seized in with a nicacil finish? Wouldn't a std hone clog the finish with grit & wear the new rings out or worse yet, clog the pores & cause lack of oil holding?
Very different! Nikasil is a plating process that still needs a honed/crosshatched surface. Also Nikasil is not compatible with chrome faced piston rings. The plasma spray bores are compatible with Chrome rings and are mirror finished.
Am I guessing right in that they clean up the bore due to contamination of the porous surface, that it's not circulating oil with contaminants like traditional hone groves. Would it make it more critical with oil for street use (daily driving), I believe some oils can produce more (if I'm not mistaken). 🤔
Also, it's known that the cross-hatch angle affects ring pack friction and oil consumption to a large degree. Does this coating allow for a lower friction (wider?) hone angle without excessive oil consumption?
I noticed your mentioning of CBN 1200 grit and later calling it Diamond. Diamond is crushed to size whereas CBN is grown to size. CBN is a much less contaminated grit. The world Premier maker of CBN is Poltava diamond Marching in Ukraine. I am testing some of their sharpening stones made of Bronze that is infused with CBN Throughout. While they are a world leader in Diamond and CBN machining tools tech. they are just now making their sharpening stones available here in the U.S..

It’s seems like a very tough coating and works great in a hard running engine but it seems to degrade over the years. The Ford guys pulling their engine after 10 years find chipping at the top of the cylinders.
Plasma spray bore, low tension piston rings, aluminum blocks and people wonder why these engine use soo much oil. What's great for race engines isn't necessarily great for street daily driven engines. I normally love Lake's videos. I'm not drinking the Kool-Aide on this one.

Rotax engines in Skidoo snowmobiles have had plasma coated cylinders since 2017.
I still like a sleeved bore in a two-stroke. The coated cylinders tend to be more prone to flaking off when you port the cylinder.

I find this interesting because period blocks can be reconditioned instead of discarded. Plasma holds where a colder "spray-weld" process might fail.
Right on!

They don't do the SUMEbore for the aftermarket in the US anymore. They have to be shipped to Europe right now.

How is it different from Nickosil? On 2stroke dirt bike engines it is nickasil applied on aluminum cylinder
Very different! Nikasil is a plating process that still needs a honed/crosshatched surface. Also Nikasil is not compatible with chrome faced piston rings. The plasma spray bores are compatible with Chrome rings and are mirror finished.

Would it make it more critical with oil for street use (daily driving), I believe some oils can produce more (if I'm not mistaken). 🤔
It is good to clean up the pores in case they have become loaded up with deposits.
Motorcycle 2 strokes use a cylinder coating
...why don't engine blocks use it ??
I've heard from a few sources that diesel oils used in gasoline engines leads to accelerated bore and ring wear. Think there's any validity to that?
It depends on several factors, but that can be the case. Diesel oils are not ideal for E85 or Methanol fueled engines.
Where can you get this sumibore process done - in Australia in particular? Not the honing but the actual coating. Is this available?
Also, it's known that the cross-hatch angle affects ring pack friction and oil consumption to a large degree. Does this coating allow for a lower friction (wider?) hone angle without excessive oil consumption?
It's available from Oerlikon Metco in Austia
Does Ford use spray bore in all of their engines or just the Coyote? What about the 3.5 Ecoboost?
Not all of their engines, but they do use it on the Coyote engines. Not sure about the EcoBoost.
So is Plasma spary is kinda the same as nikasil bore?
Different but similar
How thick is this coating
I think they said .005
Then why do these plasma bore cylinders always score?
yes "always" that's why OEM use them.
Cool. I had no idea you even could hone a plasma coated bore. Absolutely makes sense to use a very fine grit. Thanks for the video!
Looks like Chrome printing.
Is this chrome ?
I bet will be good for a lot nitrometh
Not chrome

If i brought a block into a shop for a rebuild, would the average machinist know what this is and not to bore it oversized?
I would hate to speculate on that
Nope...you'll need to educate your engine-boring machinist & pray his inflated ego allows him to learn something new.
Best regards,
Ben
you "average machinist" is never going to be tooled up to do this.
This sounds awesome but you didn’t mention anything about type of rings to use, break in etc…
Unlike Nikasil, the plasma spray bores are compatible with all standard ring materials and standard break-in procedures.
What would the ballpark cost be for having a block treated like this? Say a 3 liter straight six.
Nikasil?
Nikasil is different. The SUMEBore is sprayed on instead of a plating.
