This era has a wide usage of thermal sprays in several industries. These sprays are used for the protection of airplanes structures, buildings, and other infrastructures against extreme weather conditions, very high or low temperature, and corrosive chemicals. There are the following types of thermal spray coating processes:
HVOF (High-Velocity Oxy-Fuel Spraying)
This process involves the use of a torch. This torch spreads the flame as the nozzles are used. It produces accelerations to give high accelerations to particles. High velocity allows a very thin coating layer. Though the layer is thin but very strong and adhesive. It is more resistant than plasma coatings.
A plasma torch is used in the plasma coating procedure. The melted powder stuff is kept on the product which is almost similar to combustion flame spraying. Plasma coating sprays allow different levels of thickness. It is a much popular procedure used widely in the world. The plasma coating process can be adapted easily.

Vacuum Plasma Spraying
This process is carried out at a low temperature and controlled environmental conditions. Pressure for spraying is achieved by mixing different gases. Plasma coating is popular for vehicle bumpers, door mirrors, etc.
Combustion Flame Spraying
Combustion flame coating is very useful. Oxygen is used for producing flame which melts the mixture. It is used on surfaces that need to face lower stress.
