The influence of indentor radius on the plastic deformation has been discussed and some important results are as follows:(1) The influence of the ratio of ceramic coating thickness to indentor radius on the failure of coating, plastic deformation of substrate and crack propagation are obvious.(2)The propagation of crack in ceramic coating is assumes to be of semi-elliptical shape under normal contact with a rigid sphere.(3)Fatigue life of ceramic coating is mainly decided by substrate and load, the lower substrate elastic moduli and load, the more cycles of fatigue.

分析了压头半径对塑性变形的影响，模拟结果表明；(1)陶瓷涂层厚度和压头半径之比对涂层失效、基体塑性变形及裂纹的形成有显著影响；(2)在刚性球压头静态挤压条件下，陶瓷涂层中的预制裂纹按照椭圆形裂纹规律扩展；(3)陶瓷涂层的疲劳寿命与基体和载荷有很大关系，基体弹性模量越小，疲劳寿命延长。
