The Effect of Powders in Petrolatum on the Adhesion between Fretted Steel Surfaces

Abstract

The introduction of a petrolatum containing solid powders, metallic and non-metallic, leads to an increase in adhesion between steel surfaces at low solid content. At higher concentrations the adhesion in most cases is reduced. All the lubricant mixtures increase the fatigue life of the specimens, but there is little correlation between adhesion and fatigue life. High adhesion gives a lower increase, and unbroken specimens are associated with a low adhesion.
