Obtaining Metal-Ceramic Layers by Laser Cladding using Alumina Powder Mixtures
In the paper a comparative analyse of laser cladding behaviour of metal-ceramic powder mixture was studied. The use of In718 alloy as a matrix material, with a lower melting range than SS304, allowed the reduction of the overheating of the cladding layer, for the same values of the laser deposition parameters. At the same time, the greater fluidity of the In718 alloy led to an increase in the width of the cladded layer compared to the SS304 alloy. The use of spherical alumina particles led to the improvement of the appearance and adhesion to the substrate of the laser deposited layers. The analysis of the results obtained with laser cladding and metal matrix composite (MMC) manufactured using different proportions of Al2O3, SS304 or In718 highlighted that the optimal value of the laser melting power was of 500W for a deposition speed of 10mm/sec.
