Influencing Factors on Quantity of Cladding Parts by Coaxial Laser Cladding |
| |
| Abstract: | The technical process of the coaxial laser cladding is introduced and the reaction mechanism between metallic powder particle and laser is analyzed. The main influencing factors on quantity of cladding parts by coaxial laser cladding are discussed. The equation of the energy absorbed by the metallic powder particle from the laser beam is established. The expression of dilution and the path of improving the quality of cladding parts from material characteristics and processing parameters are presented. The key problem in coaxial laser cladding rapid prototyping is put forward. |
