The directions of research in the development of the process of plasma spraying of material are substantiated. The theoretical basis for improving the technology of plasma spraying.

In this paper, it is shown that by modulating a plasma arc, as well as the use of an air-gas mix-ture (air with propane-butane), you can signifi-cantly increase the strength of the coating coat-ing, the coefficient of use of the powder, reduce gas permeability and increase the wear resistance of plasma powder coatings.
