碳纳米管／镍基激光熔覆层耐腐蚀的原因在于熔覆层保留的碳纳米管使熔覆层更加致密，隔离了腐蚀介质，促进了镍基合金的钝化，从而提高了熔覆层的耐蚀性；同时，熔覆层中保留下来的碳纳米管和被分解的碳纳米管与金属基体形成碳化物，作为增强相均匀弥散在熔覆层中，它们的存在阻止了腐蚀坑的长大，因而蚀坑较小，耐腐蚀性得到提高。

除了穿越位错外，在两种腐蚀方法揭示出的腐蚀坑中都还存在着一种不具备穿越特性的腐蚀坑，两者在密度分布以及界面处密度增值方面具有相同的特性，但前者在宏观缺陷附近密度出现明显的增

The morphologies of the CdZnTe etch pits developed by four etchants including Nakagawa, Everson, EAg1 and EAg2 solutions are studied. The results show that the etch pits of EAg2 etchant on the (111) B surface are flat-bottomed. And the etch pits of Everson etchant on (111) B include flat-bottomed pits and pyramidal pits with different slant directions, while the positions of pyramidal pits don′t move as the surface layer is continuously removed.
