20080280027 | Method of Investigating a Coated Surface of an Object - A method of visually investigating a coated surface of an object, the coating comprising a metal or an alloy, in order to determine whether or not the coating is tight. An increasing potential is applied to the object until a desired current level has been obtained or until a maximum potential has been reached.
