The optimization of processing parameters for laser cladding process based on Statistical Analysis System (SAS) software was investigated and the experimental investigation on Ni-based alloy components fabricated by laser cladding was carried out. The influences of the main processing parameters on the surface quality were analyzed, and the Ni-based components with superior surface quality were obtained by employing the optimum set of parameters. The surface morphology and microstructure of the components were analyzed. Results indicate that the surface of the cladding is rather smooth and the claddings have a unique microstructure consisting of primary dendrite. The laser cladding layer with integrated melt interface and without reheat cracking can be obtained by optimizing the process variables. The investigations show that the components fabricated by laser cladding process have better mechanical properties than that of the conventional manufacturing technology.

This paper presents an experimental investigation on the metal components fabricated by laser cladding. In the present study, two process of laser cladding were conducted, that is pre-placed powder cladding and coaxial powder-feed cladding. The effect of processing parameters was studied and optimum set of parameters for the superior surface quality was established by employing the orthogonal design. The fabricated components were subjected to metallographic examinations and micro-hardness measurement. Results indicated that the microstructure of coaxial cladding components was finer than pre-placed powder cladding components. The micro-hardness of the fabricated specimen along and vertical the scanning direction were measured using a HVS-1000 micro-hardness tester with a 200 g 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 the coaxial powder-feed cladding layer.
