Abstract

The process of surface coating by using electric arc spray is an effort to improve the quality of the metal surface. To protect base metals from damaging environmental conditions, it is required that layer results should have feasible harshness, corrosion resistance, and layer strength. This research was aimed to find out the effect of spray distance toward harshness, corrosion resistance, and layer strength. Electric arc wire spraying used twin wires which were fed into the heat flow. An arc would arise between the ends of two wire feeds (316 stainless steel) and the heat formed would melt the ends of both wires. High-pressure gas (6 bars) was streamed to take the liquid metal to the substrate surface. The substrate surface was cleaned and roughened first by using grit blasting before being coated with the first layer of 95%Ni5%Al and the second layer of 316 stainless steel by varying the spray distance (10 cm, 20 cm, 30 cm). This technique is commonly used to coat the surface of steel roller, roller, and plastic roller and reclaim hydraulic rams, piston, axis, and pad. The test result showed higher harshness after being coated with the maximum amount of 332 VHN, acquired at 20 cm spray distance. Lower corrosion rate with the best amount of 1.1526 mpy was acquired at 30 cm spray distance. Maximum coating strength is obtained at 30 cm spray spacing at 4071.94 psi.
