Abstract
The wire arc spraying process was used to prepare FeB-based metallic glass coating and 3Cr13 coating. The effects of wear parameters, such as sliding distance, linear speed and normal loads, on the wear performances of the coatings were analyzed in detail. The results showed that, with increase in sliding distance, linear speed and normal loads, the volume losses of the metallic glass coatings increased. The relationships between wear behavior and microstructure of the coatings were discussed. The metallic glass coating had excellent wear resistance. The relatively wear resistance of the metallic glass coating was about 2.6 times that of the 3Cr13 coating under the same testing conditions. The main failure mechanism of the metallic glass coating was brittle failure and fracture.
