PROCESS DETERMINING CORROSION RESISTANCE OF DIFFUSION LAYER OF PART FROM STRUCTURAL STEEL

摘要

FIELD: testing. SUBSTANCE: tested part is subjected to nitriding. From its surface to depth of diffusion layer there are made steps with preset depth of spacing by means of grinding. After this part is kept in water for 17.0-18.0 h. Number of steps free from corrosion and depth of spacing are chosen as parameters used to evaluate corrosion resistance of diffusion layer of part. EFFECT: improved authenticity of process. 4 dwg, 3 tbl
