Abstract

The zinc based coating weight and thickness under different protective atmospheres and zinc bath chemistries were studied in laboratory by HDPS (hot dipping process simulator). The results show that, the coating had a good adhesion on matrix with no leakage and micro crack, the binder course of coating and matrix was smooth and continue. The coating weight and thickness decreased with increasing hydrogen content in furnace, but changed little for zinc bath chemistry of 0.29%Al-Zn when hydrogen content increased from 10 to 20%, they were almost the same except hydrogen was 5%. The coating weight increased significantly with increasing aluminium content solved in zinc bath, when protective atmosphere was conducted on 20% H2 appeared the largest gap of coating weight between the two zinc chemistries.
