摘要
将新工艺制造的 WC钢结硬质合金退火后经 115 0℃油淬 ,15 0℃低温回火 ,分析其磨损特性和磨损机理 ,结果表明实验合金的磨损是由硬质相剥落造成的 。
The WC steel-bonded cemented carbide manufactured by a new process was oil-quenched at 1150℃ and tempered at the low temperature 150℃ after annealing, and its wearability and wear mechanism were analyzed. The results show that the wear of the tested cemented carbide is caused by flaking of the hard phase, and that the development and propagation of cracks along the phase boundary between the hard phase and the substrate or the other hard phase is the reason why the hard phase flakes.
