  • Lubricant composition containing alkali metal borate and an oil-soluble amine salt of a phosphorus compound
    Patent number: 4472288
    Abstract: Disclosed is a lubricant composition containing an oil of lubricating viscosity having dispersed therein a particulate hydrated alkali-metal borate and an effective amount oil soluble phosphate and/or monothiophosphate compound which stabilizes the composition against the adverse effects of water contamination. The weight ratio of phosphorus from phosphates and monothiophosphates to boron in the lubricant must be greater than 0.014.
