Optimization on the process of Ni-W-PTFE composite plating through orthogonal testHE Fang-bo, CHEN Bin, LIANG Kun, LIU RuiXi＇an University of Architecture ＆ Technology, Xi＇an 710055, ChinaAbstract: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.[著者文摘]
