Laser cladding is an advanced surface modification technology, which can significantly improve the strength, thermal stability, radiation resistance, wear resistance, corrosion resistance and other properties of the matrix. Due to the complexity of laser cladding parameters and the direct impact on the quality of coatings, the traditional trial-and-error method used to explore the optimal cladding process parameters often affects the test process due to the shortcomings of high cost and low efficiency. The work aims to optimize the laser cladding process parameters of FeCoCrNiMn high-entropy alloy coatings based on the orthogonal test method, so as to improve the wear resistance and corrosion resistance of the coatings.
