摘要
运用低温深冷表面处理提高了Ｍｇ－ＰＳＺ陶瓷的表面硬度，同时其耐磨性也有显著的改善，磨损率由１．３１％降低到０．７４％。硬度、耐磨性改善的原因在于深冷表面处理后。
The wear resistance of Mg-PSZ ceramics was significantly improved using negative temperature surface treatment,and the wear rate decreased to 44% and 63% at low and high speed wear conditions respectively. This behaviour was ascribed to the compressive stress on the surface layer of Mg-PSZ by the Martensitic transformation of zirconia, after the negative temperature treatment.
