PROCESS OF APPLICATION OF ANTICORROSIVE COATINGS Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: in compliance with process ultrasonic vibrations are excited in material with in wide spectrum of frequencies depending on wave similarity and structural characteristics of material. Local section of article is excited together with anticorrosive coating applied to it. Vibrations are excited on frequency equal to frequency of natural vibrations of material of article with intensity amounting to 0.2-0.3 value of rupture stress of material of article to prolong service life of article. EFFECT: enhanced efficiency of process, increased productivity, reduced power consumption, service life of article is prolonged 3-5 fold. 3 cl, 2 dwg
