The results of the tests indicate that the spots where the fatigue short cracks initiated are at the bottom surface of the circle indention and some disfigurement places in that surface. The propagation paths of the cracks are very complex and the decentralization of the obtained data is very severe due to the micro organism of the material. While the distribution of the short fatigue cracks exist self-regularity on their length, angle, density and expansion rate of the cracks, which are less affected by the outer factors.

试验中观察到短裂纹形状多为Z型，试验结果表明疲劳短裂纹往往萌生于试样缺口底部表面和缺口表面缺陷处，其扩展复杂，路径曲折，数据分散性大，强烈地受材料微观组织的影响，疲劳短裂纹在长度、角度、密度和扩展速率方面虽数据分散但具有自身的规律，受外部因素的影响较小。

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。
