Tribological performance of NiCrAlY-Ti3AlC2-SnBiAg-Mo coatings over wide-temperature ranges: MAX phase stabilization at 800 °C

Key Points

• Tribological performance improves with the presence of max phase at elevated temperatures, particularly at 800 °C.
• Temperature variations significantly influence the durability and effectiveness of NiCrAlY-Ti3AlC2-SnBiAg-Mo coatings under stress conditions.
• Analysis using thermal and mechanical tests evaluates the stability of different coating materials over wide-temperature ranges, emphasizing their potential applications.
• Enhanced max phase stabilization suggests potential for extending the lifespan of these coatings in high-temperature applications.
