Abstract

To get a deep understanding on the relationship between process parameters of multi-layer laser cladding and performances of the coating, a Al₂O₃-13 wt.%TiO₂ nanostructured ceramic coating was prepared by quash presetting multi-layer laser cladding. Effects of three major parameters (closed loop control temperature of molten pool, ultrasonic vibration frequency and preheating temperature of incubator) on bonding strength of coating were analyzed in the laser cladding experiment through 3-factor and 3-level orthogonal experiments. Moreover, process parameters of laser cladding were optimized. Results demonstrated that closed loop control temperature of molten pool was the dominant influencing factor of bonding strength of coating, followed by preheating temperature of incubator and ultrasonic vibration frequency successively. The optimal process parameters for preparing the Al₂O₃-13 wt.%TiO₂ nanostructured coating through multi-layer laser cladding include closed loop control temperature of molten pool=2500 ^oC, ultrasonic vibration frequency=50 kHZ and preheating temperature of incubator=400 ^oC. The bonding strength of coating after process parameters optimization reached 66.3 MPa.
