Abstract: High temperature selflubricating NiAl matrix composites with addition of CuO (15, 20, and 25 wt.%) were fabricated by powder metallurgy technique, and the tribological behavior from room temperature to 1000 آ°C was ...

Abstract: Aluminum alloy metal matrix composites (Al-MMCs) have been considered as promising materials for aerospace and automotive industries due to their excellent balance of physical, mechanical, and tribological properties. In ...

Abstract: Surface modification is the major means to improving the wear resistance of copper alloys. In this study, Cu–Mo coatings were prepared on Cu–Cr–Zr alloy by laser cladding, and the high-temperature tribological properties ...

Abstract: Selflubricating composite NiAl–Cr–Mo–CaF2–Ag was fabricated by powder metallurgy technique. The NiAl matrix composite with 10 wt.% Ag provides selflubricating properties at a broad temperature range between room ...

Abstract: Wear-resistant aluminum alloys have enormous potential applications. In this paper, the Al–20Si–5Fe–2Ni alloy was fabricated by hot-pressed sintering, and its dry sliding wear behavior was investigated from 25 °C to 500 °C ...

Abstract: The synergistic effect of solid lubricants plays a significant role in wide-temperature-range lubrication, where the combination of lubricious oxide and Ag is the promising solid lubricants. In this paper, the friction and ...

Abstract: High-strength Cu–25Zn–5Al–3Fe–3Mn brass has broad applications as a wear-resistant copper alloy, while its tribological behavior at high temperatures has not yet been well investigated. In this paper, the tribological ...
