Abstract

This study investigates the dependence of reinforcing particle distribution on thermal regimes within the carbide subsystem of coatings based on 11P3AMФ2 steel, obtained through surfacing. The variations in the volume fraction of secondary carbides and residual austenite in the matrix of the deposited coating were analyzed as functions of the thermal cycle during weld surfacing. The composition of secondary carbides was compared to that of eutectic carbides. It was determined that an increase in residual austenite content enhances the wear resistance of the coatings due to the γ→α'-martensitic transformation and the presence of dispersed secondary carbides within the matrix grains. The highest concentration of dispersed secondary carbides was observed in the reinforced layer heated to temperatures in the range of 600-700 °C. The wear resistance of the obtained coatings was evaluated using quartz sand and electrocorundum abrasives.
