Abstract: Laser additive remanufacturing technology has been widely used in the repair field because of its advantages of fast repair speed and high repair quality. How to obtain the ideal service performance is the core issue of remanufacturing. The concept and process flow of laser additive remanufacturing were explained firstly, then the influence of the three factors of repair area geometry, repair area size and powder deposition path on the remanufacturing quality were summarized, and the methods to improve the quality of the repair area were summarized. Finally, the prospect of laser additive remanufacturing was pointed out.
