| Abstract: | Chromate-free surface treatment process for ZM5 magne sium alloy was discussed. Influences of factors such as pretreat ment, chemical conversion film on the quality of coating were an alyzed. The hardness, surface morphology and adhesion were an alyzed and examined respectively by micro - sclerometer, scanning electron microscope and lever style omnipotence intension test machine. Results show that the coating obtained under optimum process is uniform with better adhesion and protection to the substrate, and improves the hardness and moisture-heat resistance of magnesium alloy. |
