摘要
对内含羟胺促进剂的磷化工艺进行了研究。实验证明在低温下羟胺具有优异的促进作用和耐蚀性，特别是耐碱性。这种内含羟胺促进的无亚硝酸盐磷化可用于汽车工业。
A hydroxyl ammonium sulfate (HAS) accelerated phosphating process has been studied. It has shown that HAS shows excellent acceleration effect and corrosion protection, especially alkali resistance at lower temperature. This nitrite-free HAS accelerated phosphating process can be used in automotive industry.
