摘要：
This article explores the effect of quenching regimes on the structure and characteristics of a metal deposited by a high-chromium flux-cored wire of a martensitic class with carbide-boride-nitride doping. We established that quenching from a temperature of 1020 degrees C provides a hardness in the range of 54-58 HRC. It is shown that the hardening is caused by the formation of a martensitic structure, an eutectic composition based on chromium and iron borides, carboboride, carbide and nitride particles for the most part of chromium and titanium with increased microhardness. The hardness of such a metal practically coincides with the hardness of the metal after surfacing.
