高熵陶瓷在摩擦学领域的研究进展
The Progress of Research on High-Entropy Ceramics in The Field of Tribology
摘要
Abstract
high-entropy ceramics are a promising class of compounds made up of non-metallic elements and a variety of metallic elements with equal or nearly equal molar ratios,which have higher hardness,better oxidation and wear resistance than conventional ceramics,not only enriches the system of ceramic materials,but also has broad application prospects in the fields of thermal barriers,thermoelectricity and wear and corrosion resistance.A variety of wear-resistant high-entropy ceramics with good phase stability and mechanical properties have been developed in recent years.However the research on the lubrication mode of such materials in dry friction and high temperature friction conditions is distressed,which restricts its further development in the field of friction and lubrication.This paper aims to address this gap by discussing the intrinsic properties and preparation process of high-entropy ceramics,and focuses on the research progress of high-entropy ceramics in the field of tribology in recent years.It highlights the tribological properties of high-entropy oxides,high-entropy carbides,high-entropy nitrides and high-entropy borides from the perspectives of crystal structure and mechanical properties in succession,and discusses the potential lubrication methods of high-entropy ceramics,including the addition of solid lubricants and modulating components to achieve self-lubrication.This paper not only reviews the lubrication methods that have achieved applications in the field of high-entropy ceramics,but also summarizes some of the potential high-entropy ceramic solid lubricants with lubrication effects that have been demonstrated in the field of traditional ceramics.The appropriate lubrication can generate a friction-reducing film on the sliding surface to lower the contact stress and effectively alleviate the deterioration of friction performance under high-temperature and dry friction conditions,which are often caused by the intrinsic brittleness of ceramics and the ultimate aim is to reduce the wear rate of the material in a wide temperature range.关键词
