| 總結: | Title screen The present work is aimed at improving the method of multilayer plasma surfacing under a shieldingalloying nitrogen atmosphere. The article presents comparative studies of residual stresses formed by surfacing with 3Kh2V8, 4Kh4V10Yu, and R18Yu steel wire. The R18Yu-based wire product is shown to provide the lowest residual stresses. In addition, the improved method of multilayer plasma surfacing with heat-resistant steels under a nitrogen atmosphere is presented as preventing crack formation and increasing the hardness of the surface metal without subsequent heat treatment. Based on the results of the study, multilayer surfacing together with ferrochromium and titanium additives to the composition of the surfacing wire can be used to obtain a metal not prone to cracking in a close to hardened metal state.
