| Abstract: | Aiming at preventing the melting loss failure of the die steel surface, hard anodic oxidation experiment was carried out for aluminized 8407 steel at room temperature in order to form oxide film on the surface. The effects of current density and oxidation time on. the oxidation film thickness and hardness were investigated, arriving at the following optimum oxidation condition： current density being around 2. 5 A/dm^2, oxidation time being around 60 minutes and oxidation temperature being around 25℃. |
