ABSTRACT

The lm growth kinetics and the nature of the surface lm found for clean metal samples measured either in ultrahigh vacuum or with a microbalance are used to model the tribological chemistry occurring under extreme pressure conditions for a model lubricant consisting of methylene chloride dissolved in poly α-olen (PAO). In particular, the variation in seizure load with additive concentration measured in a pin and V-block tribometer can be calculated as a function of additive concentration.
