heal.abstract	Microstructure improvements of a Nickel electrodeposited Al-Si alloy were studied after high power laser melting treatment through a single pass or partially overlapping successive adjacent passes. In some cases laser melting treatment was preceded by a 5-hours heating of the specimens at 500-degrees-C in an Argon atmosphere furnace. Best results concerning microhardness, microstructural homogeneity, porosity elimination as well as adhesion of the nickel coating on the Al-Si alloy were achieved when the specimens were first subjected to heating at 500-degrees-C in an Argon atmosphere furnace for 5 hours and then submitted to a laser melting treatment through successive adjacent laser passes with an overlapping rate of 70%.	en
