Thermal Spraying is a group of coating processes in which finely divided metallic or nonmetallic materials are deposited in a molten or semi-molten condition to form a coating. The coating material may be in the form of powder, ceramic-rod, or wire. Thermal Spraying has advantage over other processes as it is cold process and as consequence, it never distorts parent material. Thickness of coating is controllable with, no matter what the job size is. Loss of surface properties due to wear, corrosion, abrasion, erosion, cavitation etc. can be avoided in a cost effective manner by thermal spray coating.
Coating quality is usually assessed by measuring its porosity, oxide content, macro and micro-hardness, bond strength and surface roughness. Generally, the coating quality increases with increasing particle velocities.
Several variations of thermal spraying are: Plasma spraying, Wire arc spraying, Flame spraying, High velocity oxy-fuel coating spraying (HVOF), Warm spraying, Cold spraying.
