摘要

The Fe-based bulk metallic glass (Fe_(43)Cr_(16)Mo_(16)C_(15)B_(10)) sprayed coating with the thickness about 220μm was successfully deposited on an aluminum 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 aluminum alloy metal substrate, and has a high hardness with HMV 913~1120. It has been found that better properties can be obtained in the sprayed coating by using finer powder.
