Influence of Obtaining Conditions on Microstructure, Phase Composition and Properties of Eutectic Alloy of WC-W2C System

Аннотация

The influence of the obtaining conditions on microstructure, phase composition and properties of eutectic alloy of the WC-W₂C system (relit), which is widely used as a surfacing material to strengthen the wearing parts, was installed. Using scanning electron microscopy, X-ray diffraction and durometric analyzes, it was found that the increase in mechanical properties is satisfactorily correlated with a decrease in the ratio between the number of phases of W₂C, WC and WC_1−x, the thickness of the phase layers in the grains, and the elongation of the latter.
