Melonized steel distributor gears are nitrided for wear resistance. Nitriding is a form of case hardening. The item to be treated is heated in a metallurgical oven in an atmosphere of pure nitrogen to form a very hard glass like surface. In the process of heat treatment, areas to be free of nitriding can be painted with masking clay. Cheers
I use the Comp Cams composite gear on my billet steel camshaft in my big block Chevy engines. You can use a bronze gear on the billet cam but I don’t like the way my oil looks when I change my oil, it puts a minute amount of bronze in the oil and I suppose it doesn’t hurt anything but I want to be able to do a better inspection of my oil when I take it out of the pan.
The art of selling products is to the find the lowest cost part that does the job and make sure the part is not a Chinese ripoff that doesn’t meet the specification that it claims to have. The GM melonized gear is the only one I trust to meet the melonized specification and while it’s not cheap it’s not extravagantly priced.
@@moccasinmarine i agree, it’s hard to find parts that are not made in China. I’m 74 and been a drag racer since I was a teenager and I remember when GM parts started getting parts made in Mexico and I thought that was bad. 🤦♂️

What causes the dimpled bumpy surface on the round part of the gear? If a gear did not have this dimpled appearance could it still have been nitrided?
