Thermal Spraying Processing Glossary
● What is thermal spraying? Thermal spraying is a type of surface modification method that uses heat sources such as fuel-oxygen combustion and electrical energy to heat spraying materials, creating particles in a molten or near-molten state that are then sprayed onto a substrate to form a coating. Thermal spraying has many advantages compared to other surface modification methods (such as surface hardening, carburizing, nitriding, ion implantation, plating, vapor deposition, and build-up welding). ● What is gas thermal spraying? A general term for thermal spraying conducted using a combustion flame of oxygen and combustible gas. ● What is flame spraying? A process that uses a combustion flame of oxygen and combustible gas to heat and melt linear, powder, or rod-shaped thermal spraying materials, which are then sprayed onto a substrate to form a coating. Flame spraying includes wire flame spraying, powder flame spraying (self-fusing alloy spraying), high-velocity flame spraying (HVOF spraying), and rod flame spraying (low-cast spraying). ● Wire flame spraying Uses linear thermal spraying materials. ● Powder flame spraying (self-fusing alloy spraying) Uses powder thermal spraying materials. ● Rod flame spraying (low-cast spraying) Uses rod-shaped thermal spraying materials. ● High-velocity flame spraying (HVOF spraying) Ultra-high-speed thermal spraying that uses gas flame as the heat source.
