Abstract
The cold gas dynamic spray was used to prepare the Al2O3-Cu alloys coating on Al, Cu and steel substrate in this study with the mixture of pure Al2O3 powder and pure copper powder. The influence rule of coating performance for different ratios was analyzed. The results showed that at a relatively high substrate hardness, different ratios is less effective to bond strength and vice versa. Al2O3-Cu coating on Al substrate can get largest thickness when the mixed-powder include 10% Al2O3. Al2O3-Cu coating on Cu substrate can get largest thickness when the mixed-powder include 15% Al2O3. Al2O3-Cu coating on steel substrate can get largest thickness when the mixed-powder include 25% Al2O3. Al2O3-Cu coating on Al substrate can get maximum bond strength when the mixed-powder include 10% Al2O3. Al2O3-Cu coating on Cu substrate can get maximum bond strength when the mixed-powder include 20% Al2O3. Al2O3-Cu coating on steel substrate can get maximum bond strength when the mixed-powder include 25% Al2O3. The thicker the coating thickness, the lower the bond strength.
