1·After laser melting, NiAl intermetallic play a important role of higher hardness and antiwear properties.

激光熔凝后产生的金属间化合物对提高复合镀层的硬度和耐磨性起到重要的作用。

2·From above results, a reasonable explanation has been given on the analysis basis of the states density of valence electrons of these 3d TM elements in NiAl.

通过对这些合金化元素价电子态密度图的分析，得到了比较合理的解释。
