In the ground maintenance of aero engines, high-precision and high-speed gearbox equipment are required. However, this type of equipment is prone to wear and tear on the spline part of the transmission shaft during long-term use and thus fails. At present, the main method is to replace the transmission shaft. Solved. However, due to the long and expensive purchase of new shafts, WILA uses laser cladding technology to repair the spline-worn parts of the driveshaft and evaluates the feasibility of repair.

The results show that the time cost of repairing the shaft is about 21% of that of the new shaft, and the price cost is about 40%, but the performance is significantly improved. This is because the hardness of the cladding layer is higher than that of the new shaft, and its wear resistance is better. Therefore, laser cladding technology is effective for repairing high-speed gear spline shafts.
