The results showed that the two kinds of Ni-P electroless deposits are both amorphous. The phosphorus content in the deposit using lactic acid as complexing agent is 10.04%, and in the deposit using citric acid as complexing agent is 11.93%. As the Na2S content increases, the polarizability increases, and the corrosion current and corrosion potential decrease while the Na2S content is between 1.0%~2.5%. The corrosion resistance of Ni-P electroless deposit using lactic acid as complexing agent is better than that of another kind.

结果表明，利用两种络合剂形成的Ni-P镀层均为非晶态，其中以乳酸为络合剂的镀层中P含量为l0.04mass%，以柠檬酸为络合剂的镀层中P含量为11.93mass%，在1.0%~2.5% Na2S多介质中，随着Na2S多含量的增加，阳极极化曲线的极化率增大，自腐蚀电位和自腐蚀电流降低。

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。
