Effect of Grinding Body Material on Microstructure and Properties of WC-6%Co Cemented Carbide AITranslate
Abstract AITranslate
Two kinds of grinding bodies, made with ZLT15 grade alloy(WC-20%TiC-13%Co) and traditional YG6 X grade alloy(WC-6%Co),were respectively used for ball milling of the mixture, and WC-6%Co cemented carbide samples were prepared under the same other process conditions.By testing coercive force, specific saturation magnetization, transverse rupture strength, Vickers hardness and fracture toughness of the alloy samples, analyzing metallographic microstructure and WC grain size distribution, and analyzing composition of the binder phase by SEM-EDS,the influence of grinding body material on microstructure and properties of WC-6%Co cemented carbide was comparatively studied.The results show that compared with the traditional YG6 X grade alloy grinding body, the lightweight ZLT15 grade alloy grinding body has less impact on the powder during ball milling of the mixture and lower grinding strength, which reduces processing distortion, sub-crystalline defect density and chemical activity of the powder, and decreases the driving force of grain growth during sintering.finally, the cemented carbide obtained with ZLT15 grade alloy grinding body has more uniform microstructure and better properties.
