Tribological properties of dithiocarbamate triazine and its competitive adsorption behavior compared to T701 on the corrosion inhibition of Q235 steel

Abstract

Abstract The triazine dithiocarbonate (CDMS) was synthesized from the reactions among diethanolamine, carbon disulfide and 2-chloro-4,6-dimethoxy-1,3,5-triazine. The synthesized CDMS showed excellent anti-wear and friction-reduction properties and outstanding corrosion inhibition for the investigated systems. Besides, the synergy-inhibition effect of the CDMS and T701 compound-inhibitor was investigated compared to the inhibition effect of CDMS, which showed that the inhibition effect of CDMS was superior to that of compound-inhibitor. The DFT and molecular dynamics simulations results showed that it existed competitive adsorption behavior between CDMS and T701, led to the inhibition effect of the compound inhibitor lower than that of CDMS.
