The erosion behaviour of WC-Co alloy cermets and the research on wear mechanism

Li Jian Mao Zhiyuan Huang Lanzheng Tu Jianpin(Dept. of Materials Science & Enginnering)  
Erosion resistance of two series of WC-Co cermets was examined at the impact wear rig, both of which behaved specifically as brittle materials under solid particle impacting. Their erosive behavior largely depended on grain size, hardness, component phase percentage and mophology, especially at the elevated temperatufe. Although the ultrafine cermet samples seemed to be superiour to the commercial ones against erosion, The material removal was controied by similar mechanism, The bond componant,Co,whith relatively low hardness eroded firstly and WC grain detached accordingly because of losing support under low angle impingenment by soft particle. Contrastly with hard particle erosion wear process was caused by cutting and plowing under low angle impacting and by fatigue fracture under high angle incident. Moreover a great deal of plastic deformation generally occured throughout the whole angle range.
