Two spray and coating technologies are today making full use of the world’s leading robotic thermal spray and cladding processes. They are also in full conformity with the standards laid down by the AS 9100. Spray and coating technologies now being used widely by industries across the board are that of the plasma spray and the hvof coating procedures. The plasma spray utilizes a high KW electric arc, using a plasma forming gas that is channeled through flow inducing nozzles.
It can be used at temperatures of up to ten thousand degrees Fahrenheit. The ceramic or metallic powder is injected. Thereafter the compounds are plasticized when hot gas is produced. After that, the solution is set to the desired surface at a rate of high velocity. The acronym HVOF refers to high velocity oxygen fuel. The spray that utilizes this fuel also uses oxygen. Coating materials are fed through a gun that uses nitrogen as a carrier gas.
Thereafter, the fuel gas produced meets halfway with the oxygen through a siphoned system in the gun. Thereafter, gases are emitted from the gun’s nozzle and ignition is then external. The ignition, circular in form, is, of course, aimed at the intended surface. It surrounds powdered spray material while reaching this surface. As to the finished results, readers can simply use their observational skills and even their creative imagination to detect where these two technologies can be seen in everyday life.
Metallic paint surfaces on automobiles are popular in its ability to enhance aesthetic appeal amongst its users. But more importantly is the protection and long life capabilities that these materials and the technologies used make possible. Military institutions and law enforcement agencies benefit from these technologies via the weapons inventories in service.
