КОРЕЛЯЦІЯ МІЖ ЕЛЕКТРОХІМІЧНИМИ ВЛАСТИВОСТЯМИ ЗВАРНОГО З’ЄДНАННЯ АЛЮМІНІЄВОГО СПЛАВУ СИСТЕМИ Al-Mg-Cu-Si ТА ЙОГО СТІЙКІСТЮ ПРОТИ ЛОКАЛЬНОЇ КОРОЗІЇ

Abstract

The study of the correlation between the electrochemical properties of a welded joint of an aluminum alloy of the Al-Mg-Cu-Si alloying system and its resistance against local corrosion. The technique. Potentiometry, polarization curves techniques, accelerated tests of resistance against intergranular corrosion according to GOST 9.913 were used. The measuring equipment analytical VRRL 200 scales, potentiostat PI-50.1 was applied.
