ABRASION BY LAMELLAR SOLID LUBRICANTS

Abstract

The extent to which lamellar solid lubricants (graphite, M0S2, BN, etc) are abrasive has been determined by measuring the rate of wear of phosphor- bronze sliding against PTFE in the presence of the powdered solid. Dispersions in silicone fluid are preferable to dry powder in order to avoid complicating effects due to transfer of the solid lubricant to the sliding surfaces. There are significant differences in the abrasiveness of samples of M0S2 conforming to standard specifications and it is suggested that the major factor responsible is the degree of perfection of the crystal structure. This aspect is particularly important for boron nitride and may largely account for its inability to functions as an effective solid lubricant.
