The tribological properties of two isomers (2-aminobenzothiazole and 2-mercaptobenzimidazole) with the same atomic composition and similar ring structure were investigated by using a four-ball machine and a HQ-1 ring block test machine. The X-ray Photoelectron spectroscopy (XPS) was used to detect the electron-binding energy of the additive on the surface of the wear scar to determine the tribological mechanism of the two heterocyclic compounds. The results show that the two heterocyclic compounds have similar tribological mechanism. 2-Aminobenzothiazole is superior to 2-mercaptobenzimidazole in terms of friction-reducing and anti-wear properties, as well as its bearing capacity. At the same time, the effect of the structure of heterocyclic compounds on the tribological properties is also discussed by means of molecular orbital theory and hydrogen bonding. 4, Table 4, Senate 11
