Apstrakt

U ovom radu ispitivana je korozija bakra u hidrokrekovanom baznom ulju HC-6 u prisustvu različitih koncentracija aditiva za ekstremno visoke pritiske (EP aditiv). EP aditivi se koriste za smanjenje habanja u industrijskim primenama, pod uslovima velikog opterećenja. Budući da je većina ovih aditiva na bazi sumpora čija jedinjenja mogu biti korozivna na visokim temperaturama, njihova upotreba dovodi do korozije nekih materijala. Da bi se sprečila korozija bakra u baznom ulju sa EP aditivom dodana su tri komercijalna inhibitora korozije. Po hemijskom sastavu inhibitor RC 8210 je derivat dimerkaptotiadiazola, RC 4220 sintetički neutralan kalcijum sulfonat, a IRGAMET 39 je derivat tolutriazola. Efikasnost inhibitora praćena je u skladu sa stndardnom ASTM D-130 metodom, gravimetrijskom metodom, a oksidaciona stabilnost baznog ulja praćena je određivanjem vrednosti peroksidnog broja. Oksidacija je trajala 3 i 24 časa na 100⁰C ± 1⁰C. Ispitivanje je pokazalo da je IRGAMET 39 najefikasniji inhibitor u prisustvu EP aditiva u oba ispitivana vremena oksidacije.
