摘　　要：为了消除传统的三酸抛光对环境和人体健康的危害,本文开发了一种磷酸体系的无烟不锈钢化学抛光工艺,研究了不锈钢化学抛光液的组成和抛光温度、时间等工艺参数对抛光效果的影响。利用电位-时间曲线对抛光过程进行了分析,确定了最佳的抛光工艺条件:120mL/L磷酸,60g/L硝酸钠,60mL/L盐酸,15mL/L添加剂,θ为60℃,t抛光为3～5min。In order to eliminate the harmfulness of traditional three-acid polishing method to the environment and human health,an environmental friendly chemical polishing technology composed mainly by phosphoric acid was developed. The influence of solution composition and technological parameters including polishing temperature,polishing time on surface polishing quality were studied,and the polishing process was analyzed by potential-time curves. The optimal formulation and process conditions were obtained as follows： 120mL/L phosphoric acid,60g/L sodium nitrate,60mL/L hydrochloric acid,15 mL/L additive,temperature 60℃,and polishing time 3～5min.
