摘　　要：通过正交实验确定了镀液中存在稀土CeCl3时,化学沉积Ni-P-RE合金层的镀液的组成;并采用金相显微镜观察了合金层的表面形貌,通过动电位极化曲线考察了基体和合金镀层在质量分数为3.5%的NaCl溶液中的耐蚀性。结果表明:该镀液可以在Q235钢表面沉积出表面质量良好的Ni-P-RE合金层,明显提高了Q235钢的显微硬度和耐蚀性。The bath composition of electroless Ni-P-RE plating coating was obtained through orthogonality experiment,and the surface micograph of the coating was observed by metalloscope,and the corrosion resistance of base material and Ni-P coating in mass fraction of 3.5 % NaCl solution was investigated using potentiodynamic polarization method.The experimental results show that a good Ni-P-RE alloy coating can be formed by the bath containing CeCl_3,and the coating has obviously improved the microhardness and corrosion resistance of Q 235 steel.
