摘要	为提高发动机轴承在混有0.5 wt%酸的油液条件下的摩擦学性能和耐腐蚀性，制备了一种Ti3C2Tx增强的PI/PAI/EP（MX-PPE）复合涂层。通过摩擦试验、电化学分析和分子动力学模拟，研究了MX-PPE涂层的保护机制。结果表明，1 wt%的Ti3C2Tx使纯涂层的H/E比提高了14.3%。在油酸介质中，1% MX-PPE涂层的磨损率降低了65.6%。1% MX-PPE涂层提高了摩擦学性能和耐腐蚀性。MX-PPE涂层的多层结构在滑动磨损过程中促进了层间滑动。Ti3C2Tx的表面官能团与甲酸分子发生物理吸附，形成保护屏障，防止腐蚀介质渗透。
Abstract	To improve the tribological and corrosion resistance of engine bearing under oil mixed with 0.5 wt% acid conditions, a Ti3C2Tx -reinforced PI/PAI/EP (MX-PPE) composite coating was fabricated. The protection mechanisms of the MX-PPE coating were investigated through frictional tests, electrochemical analyses, and molecular dynamics simulations. Results reveal that 1 wt% Ti3C2Tx enhanced the H/E ratio of pure coating by 14.3 %. The wear rate of the 1 % MX-PPE coating in oil-acid media was reduced by 65.6 %. The 1 % MX-PPE coating improves the tribological and anti-corrosive properties. The multilayered structure of MX-PPE coating facilitates interlayer slippage during sliding wear. The surface functional groups of Ti3C2Tx have physical adsorption with formic acid molecules, and form a protective barrier that prevents corrosive medium penetration.
