用电沉积法在不同镀液温度下制取了Cr-Mo合金镀层。於60℃5％H_2SO_4、40℃10％FcCl_3·6H_2O、30℃3％NaCl水溶液中,对在不同的镀液温度下所制得的镀层进行了腐蚀浸泡试验,测定了点蚀电位、镀层内应力、表面显微硬度以及耐磨性。结果表明,在30℃镀液温度下所获得的Cr-Mo合金镀层,其耐蚀性和耐磨性均优,具有实用性,这同此种镀层的内应力较小、钼元素含量较高等因素有关
Cr-Mo alloy films were formed by electrolysis in a patented bath at different temperatures. Corrosion rates of Cr-Mo alloy coatings in 5 % H_2SO_4 solution at 60℃ and in 10%FeCl_3.6H_2O solution at 4013 were determined. The pitting potentials of Cr-Mo alloy coatings in3%sodium chloride solution at 30℃ were determined,Internal stress,micro-hardness and wear resistance of Cr-Mo alloy coatings were tested. Results show that excellent corrosion and wear resistant coatings were formed by electrolysis in the bath temperature of 30℃. This has something to do with the higher content of Mo or less internal stresses in Cr-Mo alloy coatings at the bath temperature of 30℃.
