Beschreibung
Zusammenfassung:	corrosion tests. SUBSTANCE: procedure refers to determination of corrosion rate by measurement of electrochemical characteristics. Procedure includes measurement of polarized resistance Rpb of two electrodes made of base metal, measurement of polarization resistance Rpo of two electrodes manufactured from heterogeneous metals, one of them being base metal ( auxiliary electrode ) and the second one being tested metal ( working electrode ), and determination of corrosion rate of tested metal. Device for implementation of procedure is made of flat working electrode, flat auxiliary electrode and bushing of nonmetal material. Rugged bushing is filled with corrosive liquid. Auxiliary electrode is anchored in bushing by means of pressing lid. Elastic spacers forming local corrosion zones are placed between faces of bushing and electrodes. EFFECT: provision for quantitative determination of corrosion rate of real structures and of their welds. 4 cl, 4 dwg
