Description
Summary:In this paper, WC reinforced and non-reinforced iron-based hardfacing alloys were deposited by PTA welding. Influence of WC particles on the hardfacing alloy was revealed by analysing the microstructure, microhardness and wear behavior. The results show that the matrix metals of the two hardfacing alloys are similar in structure. The primary carbides (Fe, Cr)7C3 and eutectic carbides are distributed on the cryptocrystalline martensite and residual austenite. The distribution of the large WC particles in the whole hardfacing alloy are relatively uniform, compared with the non-reinforced hardfcing alloy, the WC reinforced hardfacing alloy exhibits higher microhardness and better wear resistance property.
