Abstract

Modern materials are protected by surface coatings to increase the material endurance. High-velocity oxy-fuel (HVOF) thermal spray coating involves injecting coating powder into an oxygen and fuel flame ejected by a nozzle. To create a thick coating that improves mechanical characteristics and boosts erosion resistance, wear resistance, and corrosion protection, the molten or semi-molten powder is accelerated towards the surface by a high-velocity gas stream. HVOF process features include spraying distance that can influence mechanical properties such as fatigue behaviour. The purpose of this research is to determine the impact of varied spraying distances for HVOF tungsten carbide-nickel (WC-Ni) coating on the fatigue characteristics of carbon steel. The fatigue test is performed on the specimens after the carbon steel has been coated with tungsten carbide nickel using the HVOF technique using the Shimadzu Servopulsor testing machine according to ASTM E466 standard for axial fatigue testing. Using the scanning electron microscope (SEM), the fracture analysis is carried out. The findings showed that the fatigue strength of the coated carbon steel decreased than the uncoated carbon steel. Also, the coated carbon steel fatigue strength increased with increasing spraying distances of 200 mm and 250 mm. There are two separate zones on the shattered surface: a burnished, smooth region and a granular, rough region. The fatigue fracture developed in the area that was burnished and smooth. Lastly, the coating that is applied to the base metal to improve the corrosion resistance would reduce the fatigue strength but not significantly.
