The Effects of Load on the Frictional Properties of Molybdenum Disulfide

Datetime:2016/7/8 21:19:35hit:10500

The Effects of Load on the Frictional Properties of Molybdenum Disulfide. The kinetic coefficient of friction was determined for several grades of commercially available molybdenum disulfide powder. These powders were individually applied to separate steel-supporting substrates to form a thin lubricant film. Friction measurements were made at loads ranging from 0.1 to 10 kg and at a slow speed of sliding. The results of Ike investigation showed that the coefficient of friction decreased with increasing load, contrary to Amontons' Second Law. A theory was postulated to explain the observed variation in the friction coefficient with load, It was concluded that the variation in the friction coefficient could be explained solely on the basis of the macroelastic and/or macroelastic and plastic deformation characteristics of the supporting substrates.
