Abstract

This study investigates the ideal spray distance to result in a high quality aluminum coating on 316L stainless steel substrates. Thermal spray process is used using Aluminum as the coating material, well-known as TSA (Thermal Sprayed Aluminum. To get high coating quality must do the coating using proper parameters, one of them is the spraying distance. In this investigation is want to observe the influence of the spray distance on corrosion resistancea and its bond strength. the spray distance variants 10, 20, and 30cm. To evaluate the corrosion resistance and the bond strength of thermal sprayed aluminum, the researchers apply a salt spray and mechanical pull-off test. The result shows that the spray distance of 20cm produce the strongest corrosion resistance and the highest bond strength, 12.5 MPa.
