Study on Technology of Aluminizing and Internal Oxidation on Surface of Cu-Al-Y Alloy
Aluminum was deposited by diffusion into Cu-Al-Y alloy substrates by the pack-cementation process. Diffusion was carried out in two kinds of container with pot-type and can-type, and the results are presented. The effects of various time and temperature on the coating characteristics of Cu-Al-Y was also investigated. The result shows that the diffusion layer is nearly 170-200 μm in thickness by aluminizing treatment at 900-950 °C for 6-8 h in pot-type container. The aluminized layers were observed by a scanning electron micrograph (SEM), we can found: A uniform coating was achieved on Cu-Al-Y alloy surface, relatively uniform thickness and even interfaces between the layers and the substrate. The diffusion coefficient of Al in Cu-Al-Y alloys at 900 °C in pot-type container can be calculated is 3.65× 10-12 m2/s.
