Abstract

The practice of using plasma surfacing and spraying in agricultural and engineering production for the purpose of restoring and hardening parts of agricultural machinery has shown a relatively high efficiency of these processes. To further improve the efficiency of these methods of restoring and hardening parts, far from all the possibilities and reserves have been used, which include a reduction in consumption and the use of cheaper working gases; expansion of the range of remanufactured parts, due to the combined use of various powder filler materials.
