Abstract

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 的协同润滑效应可改善带微孔沟道的 M50 轴承钢的摩擦学特性

本文旨在研究 Sn-Ag-Cu 和 MXene-Ti3C2 的协同润滑效应，以改善带微孔沟道的 M50 轴承钢的摩擦学性能。设计/方法/途径通过在 M50 轴承钢的微孔沟道中填充 Sn-Ag-Cu 和 MXene-Ti3C2 设计并制备了 M50 基体自润滑复合材料（MMSC）。使用多功能摩擦学测试仪对制备的样品进行了摩擦学性能测试。研究结果MMSC的摩擦学性能主要取决于MXene-Ti3C2和Sn-Ag-Cu的协同润滑效应。当微通道的孔径为 1 mm，混合润滑剂中 MXene-Ti3C2 的含量为 4 wt.% 时，MMSC 的摩擦系数和磨损率最低。Sn-Ag-Cu 和 MXene-Ti3C2 从微孔通道中挤出并扩散到摩擦界面，在摩擦界面形成了相对完整的润滑膜。同时，Sn-Ag-Cu 和 MXene-Ti3C2 的协同润滑作用提高了润滑膜的稳定性，从而获得了 MMSC 的优异摩擦学性能。通过将表面纹理与固体润滑相结合，这项工作还为机械部件的摩擦学设计提供了有益的参考。同行评议本文的同行评议记录可在以下网址查阅：https://publons.com/publon/10.1108/ILT-12-2023-0381/。
