A rather interesting thermal spraying process was developed in the USSR back in the early 1980s. It used a kerosene ramjet powered by a large air compressor to heat and propel powdered metal at supersonic velocities. It was developed for blasting and metallising gas pipelines.
nice video jim
Great video, thank you for taking the time to upload it!
Cracking video James
