Microstructure characterization and mechanical properties of Al-based coating on magnesium alloy prepared by supersonic particles deposition
Al-Si coating on the surface of AZ81E magnesium alloy was fabricated by Supersonic Particles Deposition, then microstructure observation, micro-hardness testing, bonding strength measurement and formation mechanism analysis of the deposited coating were accomplished by relative analytical techinque, respectively. The results elucidated that Al-Si coating on magnesium alloy surface prepared by Supersonic Particles Deposition was formed via the integrated combination of mechanical bonding and metallurgical bonding. The coating was compacted and its hardness was about 1.8 times to that of the substrate. Average bonding strength of the interface was above 40MPa.
