中文摘要: |
对不同载荷下n-SiC/Ni镀层在5%H2SO4 溶液中磨损试验进行了研究,通过电化学试验和失重法计算出腐蚀磨损质量损失中各分量的损失,结果表明,随着载荷的增加腐蚀磨损协同作用成为镀层失重的主要原因,并且协同作用中以腐蚀促进磨损为主。腐蚀磨损的极化曲线和表面微观形貌证实了载荷为100N 和300N时,镀层在磨损过程中没有出现钝化膜;载荷为200N,镀层表面生成钝化膜,并且钝化膜在摩擦力作用下很快破裂,从而加速腐蚀,接着又形成新的钝化膜。 |
英文摘要: |
The wear experiments of nickel-based nano-SiC coatings in 5%H2SO4 solution and under different loadings were studied. Each component of the weight loss of corrosive wear was calculated by using the electrochemical experiments and weight-loss method. The results show that synergism between the corrosion and wear is a main factor which affects the weight loss of coatings with increasing the applied loading, and corrosion promoting wear plays a key role during the synergism processing. When the applied loading of 100 N and 300 N are given, passivation films don't appear on the coatings during the wear processing; When the applied loading of 200 N is given, passivation films appear and they are broken quickly by friction, thus inducing corrosion, new films appear again, which is confirmed by polarization curves and surface micro-morphologies of corrosive wear. |
