为了消除传统“三酸”抛光工艺中氮氧化合物的污染，开发了基于湿法净化磷酸（PPA）的铝合金两酸无烟抛光工艺，并考察了各因素对6063系列铝合金工件抛光质量的影响。结果表明，在PPA 与硫酸的质量比为1．5∶1，抛光温度为100℃，抛光时间为2．5min，两酸无烟抛光添加剂 WFJK －409的用量≥4％时，抛光效果能达到“三酸”抛光时的水平。

In order to eliminate the pollution of nitrogen and oxygen compounds in the traditional three acid polishing process and response to national low -carbon environmental requirements,two acid smokeless chemical polishing process of aluminum alloy based on purified wet phosphoric acid(PPA)was developed. The influence of various factors on the polishing quality of the 6063 series aluminum alloy workpieces was in-vestigated.The results indicate that under the technological conditions with the mass ratio of PPA to sulphu-ric acid being 1.5:1,polishing temperature 100℃,polishing time 2.5min,WFJK -409 chemical additive≥4%,the same polishing effect as that of three acid polishing process can be obtained.
