The microstructure of the ceramic layer is columnar and its growth direction is perpendicular to the substrate surface.
陶瓷熔覆层的组织为柱状晶。其生长方向与基体表面垂直。
Last but not least the substrate surface temperature influences growth of the diamond due to surface diffusion and recombination effects.
最后但并不是最不重要的是，由于表面扩散和重新组合的缘故，基体表面温度对金刚石的生长也有影响。
Coating and the substrate surface temperature of the coating would have a bad contraction stress, caused by cracking and peeling off the coating.
涂层与基体表面的温度差会使涂层产生收缩应力，引起涂层开裂和剥落。
