The 2,5-bis(ethyldisulfanyl)-1,3,4-thiadiazole (T561), benzotriazole (BTA), 1-N, N-bis (2-ethylhexyl) amino-methyl-4-methyl-1h-benzotriazole (IRGAMET39) and 1-[N, N-bis (2-ethylhexyl) aminomethyl] methyl benzotriazole (TT-LX) have been evaluated as corrosion inhibitors used in rolling oil for cold rolling of copper foil. The MRS-10A four-ball friction and wear tests have been carried out to compare their tribological properties, and the lubricating performance of rolling oils has been studied through rolling experiments. The oil sample containing IRGAMET 39 has the same PB value as that one containing T561, with the coefifcient of friction increased by 35.6%and wear scar diameter decreased by 4%. The minimum rolling gauge has been studied after rolling lubrication, but the results show that inhibitors have no effect on it. Scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS) analyses have indicated that the inhibitor is adsorbed on the copper surface to prevent copper from being corroded easily. In addition, the LEXT OLS4000 laser confo-cal microscopy has been used to observe the foil surface which shows that the streaks of foil surface are clear, the scratches are shallow and the surface failure is improved effectively.
