- Abstract
- Fe-based bulk metallic glass (BMG) was sprayed through the kinetic spraying process using different conditions. By using helium as the process gas and a preheating system for the powder, it was possible to form a dense coating. This study focused on the deposition characteristics and tribological behavior of Fe-based BMG coating in comparison to the bearing materials (bearing steel and steel-backed sintered bearing) for industrial applications. Observations of the worn surface of the coating revealed that the plastic deformation with grooves and some debris were prominent with no visible cracking or fracture. Fe-based BMG coating showed a good wear resistance with a low friction coefficient.
