摘要
An object of the present invention is to provide a nozzle for a cold spray capable of continuously using a nozzle for a longer time than a conventional nozzle without causing nozzle clogging in order to efficiently obtain a high quality coating film by the cold spray method. In order to accomplish this object, there is proposed a method in which a convergent / detergent nozzle for a cold spray, which constitutes an operating gas flow passage by arranging a convergent portion, a throat portion, and a debatable portion in order along the direction in which the working gas flows from the inflow side to the outflow side, Wherein the deformant portion has a conical inner wall surface and at least a part of the inner wall surface is made of a glass material.
