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.

从过去三年中进行的大量研究中回顾了功能梯度复合材料 (FGC) 在研磨和往复测试条件下的摩擦学性能。FGC 在不同的工艺条件和参数下产生不同的磨损分析趋势。提出了一个确定工艺参数以及通过磨损模式和机制评估磨损性能的通用框架。通过独立优化工艺参数来减少摩擦系统材料损失，具体工程应用取决于工业需求。此外，讨论了磨损分析过程中面临的不同挑战，并讨论了它们在各个科学和技术领域的前景。
