The Surface Chemistry of the Mild Steel and Glass Substrates for Thermal Spray

Abstract

Abstract The surface chemical condition of substrates plays a key role in single splats formation. Single splats are the foundation of thermal spray coatings. In this study, the surface chemistry of the mild steel and glass substrates were investigated. The result indicated that the 100 °C heat treatment released the absorbents of mild steel substrates. The adsorbed water disappears from the surface of the mild steel sample after one hour of heat treatment at 100 °C; there is no adsorbed water on the surface of the glass sample.
