Purpose

This paper aims to study the synergistic lubrication effects of Sn–Ag–Cu and MXene–Ti₃C₂ to improve the tribological properties of M50 bearing steel with microporous channels.

Design/methodology/approach

M50 matrix self-lubricating composites (MMSC) were designed and prepared by filling Sn–Ag–Cu and MXene–Ti₃C₂ in the microporous channels of M50 bearing steel. The tribology performance testing of as-prepared samples was executed with a multifunction tribometer. The optimum hole size and lubricant content, as well as self-lubricating mechanism of MMSC, were studied.

Findings

The tribological properties of MMSC are strongly dependent on the synergistic lubrication effect of MXene–Ti₃C₂ and Sn–Ag–Cu. When the hole size of microchannel is 1 mm and the content of MXene–Ti₃C₂ in mixed lubricant is 4 wt.%, MMSC shows the lowest friction coefficient and wear rate. The Sn–Ag–Cu and MXene–Ti₃C₂ are extruded from the microporous channels and spread to the friction interface, and a relatively complete lubricating film is formed at the friction interface. Meanwhile, the synergistic lubrication of Sn–Ag–Cu and MXene–Ti₃C₂ can improve the stability of the lubricating film, thus the excellent tribological property of MMSC is obtained.

Originality/value

The results help in deep understanding of the synergistic lubrication effects of Sn–Ag–Cu and MXene–Ti₃C₂ on the tribological properties of M50 bearing steel. This work also provides a useful reference for the tribological design of mechanical components by combining surface texture with solid lubrication.

Sn-Ag-Cu和MXene-Ti3C2的协同润滑作用改善微孔通道M50轴承钢的摩擦学性能

目的

本文旨在研究Sn-Ag-Cu和MXene-Ti ₃ C ₂的协同润滑作用，以改善微孔通道M50轴承钢的摩擦学性能。

设计/方法论/途径

通过在M50轴承钢的微孔通道中填充Sn-Ag-Cu和MXene-Ti ₃ C ₂，设计并制备了M50基体自润滑复合材料（MMSC）。使用多功能摩擦计对所制备的样品进行摩擦学性能测试。研究了MMSC的最佳孔径和润滑剂含量以及自润滑机理。

发现

MMSC 的摩擦学性能很大程度上取决于 MXene-Ti ₃ C ₂和 Sn-Ag-Cu 的协同润滑作用。当微通道孔径为1 mm、混合润滑剂中MXene-Ti ₃ C ₂含量为4 wt.%时，MMSC表现出最低的摩擦系数和磨损率。 Sn-Ag-Cu和MXene-Ti ₃ C ₂从微孔通道中挤出并扩散至摩擦界面，在摩擦界面形成较完整的润滑膜。同时，Sn-Ag-Cu和MXene-Ti ₃ C ₂的协同润滑可以提高润滑膜的稳定性，从而获得MMSC优异的摩擦学性能。
