A plasma spray apparatus in the form of a gun is utilized to apply an antifoulant coating to marine vessels. The apparatus includes a plasma generator, an electrophoresis element, a heating element, a shield gas element, a liquid cooling system, a forced air system, and a vacuum system. The plasma generator ionizes gas to create a plasma stream, which is utilized in part to supply energy to the heating element that heats a powder material. The heated powder material is exposed to the electrophoresis element to create a covalently bonded coating material. The coating material is injected into the plasma stream and is applied to a target surface. The shield gas element injects a gas flow to surround and protect the plasma and coating material stream as the stream is in flight to the target surface. The liquid cooling system cools portions of the plasma generator and heating element. The forced air system cools a portion of the target surface as the coating material is being applied. The vacuum system removes fumes and stray particles during the application process.
