Abstract

A method for forming synthetic diamond coatings on surfaces, such as select surfaces of boat hulls, motor vehicle underbodies, chemical storage tanks and the like, which are subject to corrosion and/or erosion. In a preferred form, the apparatus is portable and is either hand-holdable or is carried by a self propelled vehicle or computer controlled automatic manipulator. In a particular form, the apparatus includes a chamber having an opening therein with a circumscribing rim adapted to be forced against a portion of the surface to be coated while one or more carbon atom, containing materials in gaseous and/or solid particle form are fed to the surface interior of such rin and form a synthetic diamond coating or the like thereagainst. Radiation directed through such chamber from a microwave generator and/or a plasma generator, is directed against such surface portion and the carbon containing material and operates to form same into synthetic diamond or diamond-like coating which becomes bonded to the surface while the housing defining the chamber is held stationery or is controllably moved across the surface by hand or by a manipulator holding such housing.
