Abstract
Disclosed is a method for reducing wear and metal fatigue during high temperature operation of a gear set, which method comprises operating the gear set with a dispersed hydrated sodium borate composition.
Claims11
A method for inhibiting gear damage, as measured by reduced wear and metal fatigue associated with ridging and pitting, during operation of a gear set at a temperature of at least 163° C., which method comprises operating said gear set with a dispersed hydrated sodium borate composition comprising:
- (a) a hydrated sodium borate
- (b) a dispersant, and
- (c) an oil of lubricating viscosity,
- wherein the dispersed hydrated sodium borate composition is characterized by a sodium to boron ratio of from about 1:2.75 to 1:3.25 and a turbidity value of no more than 300 ntu.
