摘　　要：通过正交试验,得出碳钢上电沉积Ni-W-PTFE复合镀层的镀液最佳配比为:50g/LNiSO4·6H2O,50g/LNa2WO4·2H2O,35g/LNiCl2·6H2O,40mL/LPTFE乳液。对在此条件下电沉积的复合镀层进行能谱分析,得到镀层的成分为:镍83.01%,钨11.21%,碳5.19%,氟0.58%。镀层金相组织均匀,摩擦因数为0.16,在盐酸-硫酸混合溶液中的腐蚀速率为4.9g/(m2·h)。The optimal formulation for electrodeposition of Ni-W-PTFE composite coating on carbon steel was obtained by orthogonal test： 50 g/L NiSO4·6H2O, 50 g/L Na2WO4·2H2O, 35 g/L NiC12.6H2O, and 40 mL/L PTFE emulsion. The composite coating electrodeposited under the optimal conditions was analyzed by energy-dispersive spectroscopy. The composite coating is composed of 83.01% Ni, 11.21% W, 5.19% C, and 0.58% F. The coating has homogeneous metallographic structure with a friction factor of 0.16 as well as a corrosion rate of 4.9 g/（m^2·h） in a mixed hydrochloric and sulfuric acid solution.
