In order to solve the problem of high brittleness and easy cracking of the Al₂O₃-ZrO₂ ceramic coating prepared by laser cladding technology on the surface of titanium alloy, effectively enhance the properties of titanium alloy and expand its application range, we improved the crack sensitivity of Al₂O₃-ZrO₂ ceramic cladding layer by adding rare earth oxide CeO₂ to the cladding layer material. By analyzing the macro and microstructure of the cladding layer, testing its properties, the influence law of CeO₂ content on the crack sensitivity of the cladding layer was studied, the optimal content of Al₂O₃-ZrO₂ ceramic coating prepared using CeO₂ regulation-assisted laser cladding was explored, and the action mechanism of rare earth oxide on the crack sensitivity of the cladding layer was revealed. Experimental results show that the number of cracks in the cladding layer is significantly reduced by adding rare earth oxides. When the CeO₂ mass fraction is 0.8%, the cladding layer's microstructure is the densest and the fracture prevention effect is the most visible. The fracture toughness of the cladding layer is significantly improved compared with that without the addition of rare earth control assistance, from 4.1 MPa·m^1/2 to 7.3 MPa·m^1/2.
