对于高磷的非晶态Ni-P化学镀层的晶化过程,多数研究者认为它遵循Ostwald规则:即以形核长大机制由原始非晶态经一个或几个亚稳相阶段,最终变为稳定的晶化相阶段。也有工作表明,它亦可直接晶化,得到稳定相,从而表现出所谓反Ostwald规则的现象。值得注意的是,以上多数工作均采取电镜内加热样品使之晶化尔后观察 For the crystallization process of high-phosphorus amorphous Ni-P electroless coating, most researchers believe that it follows the Ostwald rule: the nucleation and growth mechanism from the original amorphous state through one or more metastable phases, the final change Stable phase of the crystallization phase. It has also been shown by work that it can also be crystallized directly to obtain a stable phase, thereby exhibiting the so-called anti-Ostwald rule. It is worth noting that most of the above work was carried out by heating the sample in electron microscope to crystallize it
