【摘要】 本文研究热压氮化硅陶瓷与３Ｃｒ２Ｗ８Ｖ钢组成的销－盘摩擦副，在空气中非润滑条件下，４００～８００℃不同载荷（４９～３４３Ｎ）的摩擦磨损性能；测定了磨擦系数和Ｓｉ３Ｎ４销的磨损因子；通过对Ｓｉ３Ｎ４磨损面的ＳＥＭ形貌观察、Ｘ射线相结构分析，探讨了陶瓷销的磨损机理更多还原

【Abstract】 The friction and wear behavior of hot pressed Si 3N 4 ceramic sliding against 3Cr2W8V steel was investigated using an unlubricated pin on disc friction tester under different loads (49～343N) at 400℃ to 800℃; the friction coefficient and wear factor of Si 3N 4 were measured; the worn surface was analyzed by scanning electron microscope and X ray diffractometer, and the wear mechanism of the ceramie was studied.更多还原
