Abstract
This work examines the influence of tempering regimes on the structure and characteristics of a metal deposited with a high-chromium flux-cored wire of a martensitic class with carbide-boride nitride doping. It is shown that tempering at a temperature of 800 °C provides acceptable for machining values of metal hardness. As a result of the release of the metal with borides, the structure decays with the formation of a ferrite matrix, the amount of eutectics and particles of the strengthening phases decreases, and their microhardness decreases to 358-438 HV for the matrix, to 548-754 HV for the eutectic and to 1071-1174 HV for hardening phases.
