Annotatsiya. ED-20 epoksid smolasi va polisulfid oligomeri asosidagi qoplamalarning kislotali, ishqoriy, xloridli va uglevodorodli muhitlarga chidamliligini qiyosiy baholash dasturi taklif etilgan. Qoplama massasining o‘zgarishi metall korroziyasi tufayli yuzaga keladigan massa yo‘qotilishidan alohida aniqlanadi. Elektrokimyoviy impedans, adgeziya, vizual holat va gravimetriya natijalari bir-biri bilan muvofiqlashtiriladi; polyarizatsiya egri chiziqlaridan korroziya tokini aniqlashning qo‘llanish shartlari ko‘rsatilgan. Ikki komponentli kompozitsiyani tayyorlash va metall sirtiga surtish reglamenti loyihasi hamda material sarfini maydon birligiga hisoblash tartibi keltirilgan.
