Non-Metallic Alloying Constituents to Develop a Wear-Resistant CrFeNi-BSiC High-Entropy Alloy for Surface Protective Coatings by Thermal Spraying and High-Speed Laser Metal Deposition

Compositional alterations to high-entropy alloys (HEAs) allow further evolution of these materials by adjusting their property profiles. This way, they can be used for coating technologies and surface-protection applications. In the present work, minor quantities non-metallic alloying constituents, BSiC, were added CrFeNi base system. The alloy development was carried out in an electric arc furnace comparison with nickel-based Ni-600. With regard BSiC-free variant, wear resistance significantly increased. powder manufactured inert gas atomization characterized, followed processing via high-velocity oxy-fuel spraying (HVOF) high velocity laser metal deposition (HS-LMD). Depending on manufacturing conditions, proportion shape precipitates within microstructure differ. Compared both reference system as-cast condition, systems demonstrated comparable or improved wear. evaluation process–structure–property relationships confirmed great potential developing load-adapted HEA using constituents field surface engineering.
