摘要
The plasma sprayed NiAl-Bi2O3 composite coating was heat treated under the condition of argon atmosphere of 800 °C. Then, the friction and wear properties of the resulting heat treated NiAl-Bi2O3 composite coating in the temperature range from room temperature to 800 °C were evaluated by UMT-3 high temperature friction tester. By analyzing the evolution of composition and microstructure of NiAl-Bi2O3 composite coating before and after heat treatment, and deeply exploring the frictional surface/interface during the process of friction test at different temperatures, the adaptive regeneration mechanism of high and low temperature lubricating phases (NiBi, Bi2O3 and NiO) within the heat-treated NiAl-Bi2O3 coating was studied for the first time. Meanwhile, the tribological behavior of the heat-treated NiAl-Bi2O3 coating under temperature cycle test conditions of wide temperature range was analyzed in depth. The experimental results showed that the condition of heat treatment of 800 °C under argon atmosphere was able to promote the formation of dispersion-enhanced Al2O3 phase and intermetallic compound NiBi phase within the heat-treated NiAl-Bi2O3 composite coating. It was proved that the intermetallic compound NiBi had medium and low temperature lubricity in this study. At the same time, NiAl-Bi2O3 composite coating produced a significant reduction in friction and wear from room temperature to 800 °C through the heat treatment process. Especially when test temperature reached 400 °C, the friction coefficient and wear rate had a dramatic reduction, where the friction coefficient was reduced from 0.39 before heat treatment to 0.28 after heat treatment, and the wear rate was reduced by a full order of magnitude [from 35.56×10−5 mm3/(N·m) before heat treatment to 8.53 × 10−5 mm3/(N·m) after heat treatment]. When the test temperature rose to 800 °C, the contact surface of the heat-treated coating generated high-temperature lubricating phase (Bi2O3 and NiO) again through the high-temperature friction oxidation. And then solid lubricants (Bi2O3 and NiO) and reinforced phase Al2O3 adaptively formed a continuous lubricating tribo-layer on the worn surface during the sliding process, and this played a significant synergistic lubrication and anti-wear role. As a result, the lubricating performance and wear resistance capability of the heat-treated NiAl-Bi2O3 coating under the conditions of wide temperature range and high and low temperature cycle condition were significantly improved. It could be concluded that after the heat treatment, there was a mechanism of lubricating phase regeneration and continuous tribo-layer formation on the worn surface of NiAl-Bi2O3 composite coating during the friction process. This mechanism was expected to further improve the service life of metal matrix composite coatings in a wide temperature range. This study had important practical significance for the development of new technologies of solid lubrication and anti-wear materials. © 2023 Science Press. All rights reserved.
