Progress on Design, Preparation and Performance of Wide Temperature Range Self-lubricating Coating
Listed in ScienceDB
In a wide range of temperatures, performance degradation and shortened service life of mechanical components due to friction and wear have become an urgent problem in many critical engineering fields.
Description
As an effective protective measure, wide-temperature self-lubricating coatings can significantly reduce friction coefficient, slow down the wear and improve the reliability of mechanical systems, and are therefore widely used in aerospace, nuclear energy, high-temperature industrial equipment and automotive engines.
This paper firstly introduces the applicable temperature range of solid lubricants and the combination of different lubricants. Typically, wide-temperature self-lubricating coatings employ composite systems to achieve lubrication performance from room to high temperature ranges by combining metal and ceramic matrices with functional self-lubricating phases (e.g. MoS₂, WS₂, graphite, h-BN, etc.). The design strategy mainly consists of introducing reinforcing phases, developing a gradient structure coating and optimising the interface between the lubricating phase and the substrate, aiming to improve the high temperature oxidation resistance, low temperature lubricity and overall stability of the coating. Next, this paper describes the properties of metal-based and ceramic-based wide temperature range self-lubricating coatings.

According to the requirements of applicable high temperatures, wide-temperature domain coatings can be broadly classified into two categories: metal-based and ceramic-based. Subsequently, this paper outlines the lubrication mechanism of wide temperature range self-lubricating coatings. The lubricating phase plays a crucial role in the friction process, especially in high temperature environments, where the lubricating phase is able to form a protective lubricating film, which is essential for improving high temperature resistance.
The lubrication performance of the coating is closely related not only to the selection of the lubricating phase, but also to the distribution of the lubricating phase, which determines the comprehensive performance of the coating over a wide temperature range. Finally, the article points out the challenges faced by wide-temperature range self-lubricating coatings in practical applications, and gives an outlook on future research directions and their application potential.
By discussing the above, this article summarises the current research status and development trend of wide-temperature range self-lubricating coatings, which provides valuable references for further research in related fields.
