This document provides information about the 16th Basic Course on Mechanical Seals and will explain the question, "What are thermal spraying and coating?" Thermal spraying involves heating and melting the spraying material and then colliding it at high speed with the surface of the substrate to form a coating on the substrate surface. This process is referred to as thermal spraying, and it is also called coating. The purposes of thermal spraying and coating include wear resistance, chemical resistance, insulation, and release properties, among others.
