Abstract
Abstract
Attapulgite rod clay (ATP) powder has been widely studied as a high-quality lubricant additive, but its anti-wear and antifriction mechanism has not been clearly explained. To solve this problem, oil samples with different attapulgite powder contents were prepared in this study, and friction and wear tests were carried out to test the friction coefficient on the surface of the friction pair. Finally, X-ray photoelectron spectroscopy was used to verify the analysis results, and the mechanism of anti-wear and friction reduction of attapulgite powder was revealed fundamentally. The research results show that the reason why the lubricating performance of the oil sample is closely related to the amount of attapulgite powder is the proportion of Al2O3 and Fe2O3 in the friction layer, indicating that the lubricating performance of the oil sample is positively correlated with the proportion of Al2O3 and Fe2O3 in the friction layer.
