METHOD OF CONTACTLESS CHECK OF NONMETALLIC COATINGS ON A METALLIC BASE,

Abstract

A method of contactless check of the nonmetallic coatings on a metallic base with the aid of a radioactive source of radiation, which excites characteristic radiation in the base and coating of the part to be checked and ionizes the air gap between the source of radiation and the part, which is distinguished by the fact that for the purpose of simultaneously checking the thickness of the layer of the coating and its discontinuity, the latter is determined by a gas discharge which occurs on the presence of discontinuity in the nonmetallic coating on a metallic base (substrate source of the radiation, for example tritium) and the part to be checked.
