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.
