The tribological performance of functionally graded composites (FGCs) under abrasive and reciprocating test conditions are reviewed, from the numerous studies performed over the last three decades.
FGCs produced differing wear analysis trends under varying process conditions and parameters.
A general framework identifying the process parameters as well as assessing the wear performance through wear modes and mechanisms is presented.
The tribo-system material loss is reduced by optimizing the process parameters independently, for specific engineering applications depending on the industrial demands.
Moreover, the different challenges faced during wear analysis were discussed and their prospects in various scientific and technological fields are addressed.
