NiTiAl-based self-lubricating composite with self-regulation function and manufacturing method thereof

The invention discloses a NiTiAl-based self-lubricating composite with a self-regulation function. The NiTiAl-based self-lubricating composite comprises a basis material, a solid lubricating phase, alubricating behavior regulating agent and a sine-cosine curve pore structure. NiTiAl is used as the basis material, MgZnCu is used as the solid lubricating phase, and LiMg-SiC is used as the lubricating regulating agent. The MgZnCu solid lubricating agent is used to reduce the tribological property of the NiTiAl composite. The lubricating behavior of NiTiAl-MgZnCu composite is regulated by the LiMg-SiC, so that the NiTiAl-based self-lubricating composite presents the good lubricating behavior. The NiTiAl-based self-lubricating composite with the self-regulation function and the manufacturing method are used to solve the problems of friction, wear and lubrication of mechanical parts under extremely complex conditions such as high temperature and high load. 本发明公开种具有自我调控功能的NiTiAl基自润滑复合材料，它包括基体材料、固体润滑相、润滑行为调控剂以及正余弦曲线式
