FIELD: chemical coating of metal powders. SUBSTANCE: apparatus has ultrasonic generator with converter, wave guide emitter system with a set of longitudinal oscillation wave guides formed as bars fixed and interconnected in series. Flexure oscillation wave guides are positioned between longitudinal oscillation wave guides in planes perpendicular to their axes. Reaction bath is further equipped with drain opening and devices for continuous feeding of powders and reaction water. Apparatus allows capacity to be increased by 2-3 times with equal power consumption. EFFECT: increased efficiency by continuous cementation and and powder cleaning process, uniform coating over the whole surface of powder particle and efficient removal of chemical reaction by-products from metal powder surface. 1 dwg
