摘　　要：介绍了锌铬涂料和无铬锌铝涂料的基本组分,并对这两种涂层的性能进行检测。结果表明:无铬锌铝涂层的外观和耐盐雾性较锌铬涂层略差,而附着力和硬度略优。分析了产生这些区别的原因。The basic components of Zn-Cr coatings and non-chromium Zn-Al coatings were introduced. The several properties of two coatings were tested. The results showed that the appearance and salt spray resistance of non-chromium Zn-Al coating was slightly worse than those of Zn-Cr coating,and adhesion and hardness of the former were slightly better. The reasons for these performance differences were further analyzed.
