摘要
对高磷 ( 12 .8%P)化学镀Ni -P合金镀层进行了 75 0℃高温热处理 ,研究了经高温热处理后镀层的耐蚀性。结果表明 ,高温热处理后 ,镀层耐蚀性大大优于镀态。晶粒长大、晶界面积减少以及镀层表面生成较厚的。
The high phosphorus content(12.8%P)coating was heat treated at 750 ℃. It was studied the corrosion resistance of coating by heat treatment. The results showed that the corrosion resistance of coating by heat treatment at 750℃ prefers not to be heat treated and being heat treated at 500℃. The main cause that corrosion resistance increases is that crystallizing granules grow,the surface of interface of cystallizing granules decrease and the thicker oxidation film is formed on the interface of coating.
