Thermal Spraying
This page last reviewed January 25, 2010
BACKGROUND
Thermal spraying is a process in which metals are melted and sprayed on a surface to form a coating. Other names for thermal spraying include flame spraying, metallizing, and hardfacing. The metals that are sprayed can be pure metals or alloys that are generally in the form of powders, wires, or rods. During the metal spraying process, air emissions can include metal fumes and small metal particles that may be toxic. The Air Resources Board is investigating whether the air emissions from thermal spraying need additional controls to protect public health. This website contains information on ARB's investigation and regulatory developments.
