摘要
采用腐蚀失重法和极化曲线法 ,研究了稀土氧化物 (La2 O3 )对刷镀镍磷合金镀层在 10 %HCl中耐蚀性的影响。结果表明 ,镀液中加入适量La2 O3 可明显改善镀层的耐蚀性 ,分析讨论了稀土的作用机理。
The effect of lanthana on corrosion of brush plating Ni\|P alloy in 10% HCl solution was studied by using weight loss and polarization curve methods. Results showed that corrosion resistance of alloy plating was improved markedly while adding an amount of lanthana in bath. Else the action and mechanism of lanthanon were discussed.
