| Abstract: | Laser cladding forming experiments were carried out with nickel-based and 316L stainless steel alloy powder as cladding material.Metallic components with dense microstructure were formed.It analyzed effect of material ingredient on crack forming by cladding experiments of single cladding,multiple cladding and gradient material cladding of nickel-based alloy.Laser cladding experiments under ultrasonic vibration were carried out,and the experimental results show that vibration-assisted cladding method significantly improves microstructure and hardness of cladding. |
| Keywords: | cladding forming gradient material crack flaw ultrasonic vibration |
