Abstract：In order to effectively improve the interface bonding strength between the cladding layer and the matrix in laser cladding repair,the process method of synchronous auxiliary mechanical hammering was adopted in the laser cladding process.The response surface analysis method was used to optimize the combination of mechanical hammering parameters,include the mechanical hammering force,hammering frequency and hammering frequency,taking the tensile strength,elongation and micro-hardness of cladding formed structure as the optimization goal,to obtain the ideal interface bonding strength between the cladding layer and the matrix.The results show that the comprehensive mechanical properties are the best,the tensile strength is 1 209 MPa,the elongation is 11.8％,and the micro-hardness is 486HV,when the mechanical hammer force is 2 000 N,the hammer frequency is 3 times,and the hammer frequency is 2 Hz.
