It is found that the structure of the ternary electroless Ni-W-P coating is greatly influenced by W content in the deposit. It is also found that the requisite content of phosphorus for amorphous Ni-W-P structure is less than that of Ni-P binary alloy coating, and the more tungsten exists, the less phosphorus is required. The hardness of the deposits will be enhanced as the deposit structures are changed from amorphous to mix-or nanocrystalline structures. The corrosion resistance of Ni-W-P ternary alloy is improved as W content increased, and the passivation of amorphous deposits is formed more easily than that of mix-structure and nanocrystalline deposits.

研究发现，化学镀Ni-W-P三元合金镀层的结构受镀层中钨含量的影响较大，非晶态Ni-W-P三元合金镀层所需磷含量较非晶态Ni-P二元镀层所需磷含量要低，并且钨含量越高，所需磷含量越少；镀层硬度随镀层结构从非晶态→混晶态→纳米晶态转变而增加；镀层的耐蚀性随镀层中钨含量增加而变好，且非晶态镀层较混晶态和纳米晶态镀层更易形成钝化区。
