Abstract: Shaft parts, as critical components in high-end equipment such as engineering machinery, automobile manufacturing, and aerospace, often fail during service due to wear, corrosion, and fatigue, directly affecting the smooth operation, reliability, and service life of the equipment. Laser remanufacturing technology, as an efficient and precise surface engineering and additive manufacturing method, shows great application potential in the remanufacturing of shaft components due to its advantages of concentrated heat input, small heat-affected zone, metallurgical bonding , minimal deformation of the cladding, and excellent properties of the cladding layer. The research progress of laser remanufacturing technology in the application of shaft components is summarized, the influence of laser cladding process parameters on the remanufacturing surface and performance of shaft components is focused on, the research status of cladding material systems is sorted out, and the application of simulation technology is discussed. Finally, the insufficiencies and future development directions of laser remanufacturing technology are prospected.
