摘　　要：采用中温酸性化学镀工艺在低碳钢表面镀Ni-P合金,并以沉积速率为评价指标,采用正交试验法进行工艺优化。确定最优镀液配方与工艺条件为:nNi2+∶nPO2-20.40,乳酸20mL/L,冰乙酸10mL/L,乙酸钠15mL/L,pH值5.3,(75±2)℃。结果表明:在最优镀液配方与工艺条件下,沉积速率达到20μm/h,获得的Ni-P合金均匀致密、与基体结合牢固且耐蚀性良好,其中磷的质量分数约为9.1%。Ni-P alloy was prepared on low-carbon steel by electroless plating from mid- temperature acidic bath, and the electroless plating process was optimized by orthogonal experiment method selecting deposition rate as evaluation index. The optimum compositions and conditions were nNi62＋：nPO2^2- 0. 40, lactic acid 20 mL/L, glacial acetic acid 10 mL/L, sodium acetate 15 mL/L, pH value 5.3 and temperature （75±2） ;C. Results showed that, under the optimum conditions, the deposition rate reach 20μm/h, the obtained Ni-P alloy was uniform and compact, combines with the matrix firmly and present excellent corrosion resistance. The phosphorus mass fraction was about 9.1%.
