Surface Engineering and Thermal Spray Coatings: Processes, Benefits, and Applications on SS304 Substrate

Abstract

Surface engineering has evolved as a vital technology for improving engineering component performance and longevity, particularly in harsh industrial environments. Thermal spray coatings are a versatile and effective way for improving surface qualities like as wear resistance, corrosion resistance, and thermal stability. This literature study focusses on the application of thermal spray coatings to SS304 stainless steel substrates, which are widely utilised in the chemical, automotive, and aerospace industries due to their outstanding corrosion resistance and mechanical qualities. Various thermal spray techniques, including as plasma spraying, High-Velocity Oxy-Fuel (HVOF), and flame spraying, are investigated in terms of process parameters, coating materials, and microstructural results. The advantages of these coatings, such as increased hardness, lower friction, and longer component life, are discussed. Furthermore, the present  research looks at practical applications in which thermal spray coatings greatly increase the performance of SS304 components. This research work summarized the effectiveness of thermal spray techniques as a surface engineering solution for prolonging the operating life of SS304 components in severe applications and the various materials are processes by Thermal Spray coating process.
