METHOD OF PLASMA APPLICATION OF COATS Russian patent published in 2003 - IPC

Abstract RU 2198239 C2

FIELD: mechanical engineering; nuclear power engineering; metallurgy; reconditioning of dies in case of wear. SUBSTANCE: method includes abrasive-jet treatment of surface, application of intermetallic compound Ni-Al on surface at thickness not exceeding 2 mm, contacting the surface with plasma jet, excitation of electric arc and feeding the material of coat to plasma jet; AC or pulsating current electrical arc is excited in said method. Rate of motion of plasmatron shall be no less than product of excitation frequency of spot on surface of part by size of this spot. EFFECT: improved quality of coat. 2 dwg, 1 ex
