Abstract
Combinations of an oil-soluble tin compound, e.g., dibutyl tin dilaura te, with organoborates either sulfurized or nonsulfurized, give better antiwear performance than the individual components. A synergistic me chanism is postulated such that boron atoms with vacant p orbits catal yze triboreduction of tin compounds on rubbing surfaces, producing ele mental tin. The tin deposits on and alloys with the metal surface to p rotect the substrate against wear.
