摘　　要：用化学镀方法分别获得不同磷的质量分数的Ni-P合金镀层,并用X射线衍射仪和扫描电子显微镜分别研究镀层结构和表面形貌。对经不同热处理温度下,Ni-P合金镀层的耐蚀性能作了对比研究。结果表明:热处理影响了镀层的耐蚀性,经200℃热处理1 h,可改善镀层的耐蚀性;温度超过300℃,镀层组织结构发生改变,耐蚀性能降低。Ni-P alloy coatings with different mass fraction of P are prepared by electroless plating process, and the structure and surface morphology of the coatings are examined by X-ray diffraction and scanning electron microscopy respectively. The corrosion resistance of the Ni-P coatings at different heat treatment temperatures are investigated. The results show that the corrosion resistance of the coatings is directly influenced by heat treatment. Heat treatment at 200℃ for one hour can improve the corrosion resistance of the coatings, however if temperature exceeds 300℃, the coating structure will be changed, and the corrosion resistance reduced.
