In this study electroless Ni-P coatings were deposited on W302 steel substrates. The effects of bath pH and heat treatment at 400?C were investigated on the surface morphology, phase structure, phosphorus content, thickness and microhardness of the coatings. It was observed that both the phosphorus content and coating thickness are dependent on the bath pH. In an acidic/neutral bath, low and medium phosphorus coatings with thickness of 13.9-19.8 ?m were synthesized, while in an alkaline bath, high phosphorus, 4.8-5.8 ?m-thick coatings were formed. Coatings containing medium or high P seemed to be amorphous, while low P coatings had microcrystalline structures. Hardness was also dependent on the composition of the coating. After heat treatment, the structure of the coatings transformed into crystalline Ni with the precipitation of Ni3P phases, which resulted further increases in hardness.

The Relationship

In the paper, different phosphorus content Ni-P coatings was prepared by electroless plating. The microstructural changes of electroless Ni-P coatings on both as-deposited condition and heat treatment were investigated by X-ray diffractometry (XRD). The relationship between microstructure of Ni-P coatings and phosphorus content and heat treatment temperature were discussed. This conclusion provided a good theoretical basis for Ni-P coating using for wear and corrosion resistances in the technology of MEMS.
