FIELD: technological processes, metal working.
SUBSTANCE: invention is related to the field of metal products cleaning, such as rolled wire, wire, strip, forged pieces, foundry and others, in particular, to method for electroarc processing of metal products surfaces and may find application in different branches of machine building industry. Prior to arc discharge treatment, surface is previously coated by thin layer of alkaline, alkali-earth or rare-earth metals or their compounds in process of hot processing or in cold condition. Prior to processing, at atmospheric pressure processed surface is previously coated by material, which is gasified by cathode spots of arc, creating protective or restorative medium above cleaned surface. Result achieved is considerable reduction of metal products processing cost, higher efficiency of processing and lower heating of processed product metal.
EFFECT: reduction of metal products processing cost, higher efficiency of processing and lower heating of processed product metal.
