| Abstract: | Oil-soluble stannous naphthenate (SN) is synthesized by using naphthenatic acid and SnO.And its molecular structure is confirmed by IR and multielement oil analyzer (MOA).The tribological performances of the organotin as lubricant additive are evaluated with a four-ball friction and wear tester.These experiments indicate that the wear scar diameter (WSD) and friction coefficient are diminished while the load-carrying capability increased by comparison with that of base oil.The elemental composition of the boundary lubricating film is examined by means of Auger electron spectroscopy (AES).Synergistic effect is found in the load-carrying capability of the complex of SN and sulfured olefin.The analytical results of AES indicate that the good performance of stannous naphthenate is attributed to the formation of a boundary lubricating film containing Sn on the rubbed surface. |
