摘要：
The Fe-based bulk metallic glass (Fe43Cr16Mo16C15B10) sprayed coating with the thickness about 220 mu m was successfully deposited on an aluminium alloy (A5052) metal Substrate using an HVOF (High Velocity Oxygen Fuel) spraying process. All sprayed coating has still kept the amorphous state after spraying. The Fe-based bulk metallic glass coating shows good adhesion to the aluminium alloy metal substrate, and has a high hardness with HMV 913 similar to 1120. It has been found that better properties can be obtained in the sprayed coating by using finer powder.
