Paper Title:
Experimental Study on the Nickel-Based Metal Parts Manutactured by Laser Cladding
  Abstract

This paper presents an experimental research on the metal parts manufactured by laser cladding. The present studies showed two processes were conducted ,including coaxial powder-feed cladding and pre-placed powder cladding. The effect of processing parameters were studied and optimum set of parameters for the superior surface quality was established by employing the orthog -onal design. The manufactured parts were subjected to metallographic examination and micro -hardness measurement. Results showed that the microstructure of coaxial cladding parts was better than that of pre-placed powder cladding parts. The micro-hardness of the manufactured specimen along and vertical the scanning direction were measured using a HVS-1000 micro-hardness tester with a 200g applied load. Analysis of the physical properties provided further evidence of differences in micro-hardness produced by different process conditions, and the average micro -hardness value of pre-placed power cladding layer was lower than that of the coaxial powder-feed cladding layer.
