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