Additives and lubricant formulations for improved antiwear properties

Carl K. Esche, +4 more
TL;DR: In this paper, a base oil of lubricating viscosity and an amount of a hydrocarbon soluble titanium compound was used to reduce surface wear between metal parts, which was shown to provide a reduction in surface wear greater than a surface wear of a lubricant composition devoid of the hydrocarbon-soluble titanium compound.
