Use of Hot Hydrocarbons in a Plasma Installation for Application of Wear-Resistant Coatings

Results of comprehensive research on the use of exhaust gases from an internal combustion engine (ICE) as the source of hot hydrocarbons instead of propane-butane or natural gas to reduce oxidative processes are presented. Introduction of hot hydrocarbons in exhaust gases from an ICE is shown to reduce significantly the redox potential of a plasma-torch plasma jet with respect to the sprayed material. An experimental mobile multifunctional plasma installation is developed and enables air-plasma spraying and melting of applied wear-resistant coatings. In this case, the exhaust gases from an ICE are used as the plasma-forming gas.
