The metalbacked selflubricating composite is compounded with a metal substrate,which ensures the composite owns supreme mechanical,lubrication and reliability performance.While the application has been developed from aerospace to the various civil application fields.The major composition of the composite is firstly summarized,including the types and functions of metal backing and lubricating fillers,considering the metal backing with better comprehensive and wider temperature range should be selected,and the multifiller mixed friction mechanism should also be studied.Then the advantages and disadvantages of the preparation processes for the composite are introduced and compared,including the adhesivejoint,laser cladding and microarc oxidation treatment.It is considered that the preparation process needs further study in order to improve the tribological performance,bonding strength,composites reliability,etc.which helps the composite to meet higher application requirements.Attention should also be paid to the development of emerging manufacturing processes.Finally,the friction and wear mechanism of composite is introduced,indepth study on the failure mechanism of the lubricating layer is needed in the future,and the influence of metal backing and environment on the tribological properties of composite also needs to be analyzed.
