Abstract : Thermal spraying is a broad terminology for a coating process in which materials are deposited in a spray of finely distributed liquefied or semi-liquefied particulates to build layered deposition coatings. Duplex and composite coatings can be utilized in the thermal spray technique to enhance the tribological properties of a broad range of engineering materials while saving money; service life extension, maintenance expenses, and replacement costs are lower than for single-layered coatings. As a result, this paper critically analyses various pre-processing surface treatments for substrates, commonly used thermal spray processing methods, and various post-processing surface treatments for thermally sprayed substrate materials. This paper also includes a description of several characterization methodologies as well as some comprehensive prospective applications for engineering components with challenges and scopes. Thus, this paper provides a fundamental understanding of surface treatments to researchers who use thermal spray coating techniques.
