ASSESSMENT METHOD OF RESISTANCE OF STEEL ITEMS AGAINST LOCAL CORROSION Russian patent published in 2014 - IPC G01N33/20 G01N17/00

Abstract RU 2504772 C1

FIELD: metallurgy.

SUBSTANCE: samples are taken from items; specimens with polished surface are produced; surface of specimens is treated with solution of 3-10% ions of rhodanate during 3-5 hours at pH 8.0-9.0. Then, quantitative analysis of sections damaged and undamaged by corrosion is performed by means of computer functions of the programme for processing of pictures, and corrosion resistance of items is estimated as per fraction of damaged surface.

EFFECT: improving informativity and reliability of assessment.
