| Abstract |
The corrosion and the microstructural properties of evaporated Al-Cr films on the steel strip by two-source evaporator have been investigated. The corrosion resistance of Al-Cr coated steel was evaluated by the salt spray test as well as the anodic polarization test in 0.1N NaCl. Porosity of coated Layer was also compared with the corrosion resistance property. Corrosion resistance was improved with increasing the Cr content in Al-Cr films, and it was the maximum in the Cr content of 10 to 15wt%. However, corrosion resistance was decreased over 15wt% of Cr content films, it was thought to be due to porous microstrucute resulting from the formation of intermetallic compound phases. |
