СПОСОБ ГАЗОТЕРМИЧЕСКОГО НАНЕСЕНИЯ ПОКРЫТИЙ НА ВНУТРЕННИЕ ПОВЕРХНОСТИ ОТВЕРСТИЙ

摘要

FIELD: mechanical engineering. ^ SUBSTANCE: method comprises setting the reflecting member in the opening in front of the nozzle of the spraying burner and rotating the member in the course of coating. The reflecting member has sloping surface. The nozzle and reflecting member move one with respect to the other in a given trajectory. The axis of the nozzle is shifted with respect to the axis of rotation of the reflecting member. The reflecting member is additionally cooled by means of one or several nozzles arranged in the vicinity of the spraying nozzle. The exhaust gas is forcedly evacuated from the side of the nozzle opposite to the opening. The reflecting member vibrates within the ultrasonic frequency range. During coating, the part to be coated rotates around the axis of symmetry of the opening. ^ EFFECT: enhanced quality of coating and prolonged service life of the reflecting member. ^ 7 cl, 3 dwg
