A protective coating applied to the underwater portion of a marine vessel operable to inhibit the growth of marine foulants. The coating comprises a polymer, a marine biocide, a preservative, and optionally an antimicrobial agent. In certain embodiments, the marine biocide, preservative, and optional antimicrobial agent are chemically bonded with the polymer thereby significantly reducing the ability of the biocide, preservative, and antimicrobial agent to leach from the coating into the surrounding environment.

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.

An improved, relatively permanent operating head for stud welding guns is provided which eliminates the need of ferrule replacement after each welding sequence, thereby greatly speeding up and facilitating the welding operation, and lowering the cost thereof. The head includes an elongated, metallic, notched, dielectric-covered ferrule surrounding the usual stud-conveying chuck provided with the gun, along with air cooling apparatus for directing circumferentially spaced air currents through and exteriorly of the permanent ferrule to extend the life thereof and minimize buildup of slag thereon. In preferred forms, an inner, electrically insulating phenolic sleeve is disposed between the chuck and ferrule, and the work end of the latter is coated with an initial layer of tungsten carbide and an outer layer of tantalum for maximum heat resistance and electrical insulation.

An improved, environmentally safe protective coating for marine surfaces is provided which is specially formulated for application to boat hulls for resisting marine growth thereon while minimizing release of toxic antifoulants into the environment. The coatings of the invention can therefore be used on boat hulls for preventing marine growth without the severe pollution effects associated with conventional antifoulant paints. The coatings are preferably made from powdered mixtures which include respective quantities of Nylon 11, an inorganic porous carrier such as carbon black, and an antifoulant such as tributyltin fluoride. Application of the mixture to marine surfaces involves providing a supersonic gas stream, passing the gas stream through an electric arc thereby heating the gas stream and converting a portion thereof to plasma, injecting a quantity of the powdered mixture into the heated gas stream substantially downstream from the arc so as to melt the powder without overheating it, and then spraying the melted mixture onto a surface whereupon it cools and provides a bonded protective coating thereon.
