The demands for thermal spray coating are becoming more and more stringent. Environmental concerns are also being considered as an integral part of the design process. For future economic competitiveness and a lower environmental impact, we must, therefore, turn our attention to processes that use the minimum of resources. Thermal spraying is an attractive coating technique as it offers a wide choice of materials and processes that have a reduced impact on the environment when compared to conventional plating processes. Thermal spray coating techniques Techniques such as HVOF, flame wire spraying, flame powder spraying, arc wire spraying, plasma spraying, and cold gas spraying, allow many problems of wear, corrosion and thermal degradation to be resolved by engineering the surface with tailor-made coatings. In the simplest terms possible, thermal spray coating involves heating a material in powder or wire form to a molten or semi-molten state. The material is propelled usi...

Nowadays, the thermal spray coating is utilized in a number of different industries. This coating consists of wire and molten powder which are exposed to plasma or oxy-fuel combustion. The fire from the spray device will power the mixture that has been heated, and once it has been sprayed onto metal, the mixture will retain a firm coating. Thermal spray coatings are used in a wide the spectrum of many useful applications, which can include protecting airplanes, buildings and other structures from extreme temperatures, chemicals or environmental conditions such as humidity and rain. Here are the 5 most common processes to generate thermal spray coatings today: Vacuum Plasma Spraying Vacuum plasma spraying is done in a controlled environment, but utilizes low temperatures. This maintains the vacuum while also reducing damage to the material. A variety of gas combinations can be used to get the necessary pressure for spraying. Vacuum plasma spraying is used for items suc...
