本研究开发了一种新的氮化铝生产方法。该方法可在铝表面形成高附着力、高厚度的氮化铝层。研究了合金元素对氮化铝形成的影响。结果表明，合金元素中的铜和硅阻碍了氮化层的生长。镁元素促进了氮化层的生长。此外，氮化物层的生长也影响了作为晶界的微观组织。

A novel method for the production of aluminum nitride is developed in this study. Aluminum nitride layers with high adhesion and high thick can be formed on aluminum surfaces using this method. The effect of alloying elements on the formation of aluminum nitride is also investigated. As the results, the growth of the nitride layer is obstructed by the copper and silicon in the alloying elements. The growth of the nitride layer is promoted by magnesium elements. Furthermore, the growth of the nitride layer also influences the microstructure as a grain boundary.
