Study On Multi-element Penetration And Heat-treatment Of Copper And Brass

In this paper, Al-Mn-Fe multi-element penetration has been carried on copper, power aluminized and Al-Mn-Fe multi-element penetration have also been carried on brass respectively. The process of co-penetration, layer micro-structure and diffusion mechanism were investigated in details. The hardness, the corrosion resistance and the friction wear properties were studied on penetrated copper, heat treated samples and penetrated brass. The high temperature oxidation resistance of penetrated copper and heat treated samples were investigated. The experiment results show that after multi-element penetration, the oxidation rate of copper is almost reduced 10 times, relative abrasive resistance is 4.8 times that of copper, the corrosion depth is reduced more 50%. The high temperature oxidation resistance, wear resistance and corrosion resistance of multi-element penetration have got improved further after heat treatment, The properties of solution cryogenic directly and ageing sample is better than others. The properties of multi-element penetrated brass are better than aluminized brass. The abrasive resistance of multi-element penetrated brass is 11.2 times of brass and the corrosion depth is reduced more 30% in three solutions.
