Coating of surface is a cost-effective way to make materials, equipment, and machine components with desired surface characteristics including high hardness, resistance against erosion, wear and corrosion. To obtain the necessary characteristics, several coatings are employed. The surface characteristic of the AISI1045 steel is not optimum, despite its desired strength, resistance against wear, hardness or corrosion. Thermal spraying is currently a leading way in which materials are avoided for days to wear abrasively, corrosion at high temperatures, erosive wear and stress because of increased material life in use. Spraying using high-velocity oxygen fuel (HVOF) is a kind of thermal spraying noted for its resistance against wear, micro-hardness and thick micro structured coatings. The aim of this review paper is to provide a state-of-the-art about the research done by various scholars to improve physical, mechanical, wear, erosion and corrosion characteristics of AISI 1045 by the application of different or combination of coating powders utilising the HVOF Spray method.
