【摘要】 分别研究了酸性镍-磷镀层、碱性镍-磷镀层、酸性镍-磷-铜镀层的耐蚀性及它们对底材A3钢耐蚀性的影响.认为当镀层质量较好时,耐蚀性较强,但如果镀层存在缺陷,则易引起底材局部腐蚀;双层镀对抑制局部腐蚀有利.更多还原

【Abstract】 Corrosion resistances of acid NiP coating, basic NiP coating, acid NiPCu coating & basic NiP coating and their influences on corrosion resistance of A3 steel are studied. The results indicate that the corrosion resistance of coatings with good quality are advanced, and flaws in coatings will result in partial corrosion in A3 steel. It is showed that the doubledeck is favorable to resist partial corrosion.更多还原
