Self-Lubricating Composite Materials for Dry Friction
Journal Title: Tribology in Industry - Year 2009, Vol 31, Issue 1
Abstract
In certain applications under dry friction, the composites, containing small amount of solid lubricant, work very effectively. The copper matrix composite alloyed with metals and phosphorous and containing globular inclusions of lead is among these. During the friction process, the lead acts as solid lubricant.. Shortcoming of these materials is that lead’s high toxicity makes them inapplicable according to ecological requirements. This necessitates replace lead by other solid lubricants and in particular by molybdenum disulfide (MoS2). The results of tribological study of this material show his antifrictional efficiency. The received experimental data for friction coefficient in vacuum were significantly smaller that the friction coefficient of materials, containing lead as lubricant. The measured values for friction coefficient in vacuum were 0,050 – 0,062 and for wear were smaller of 1.10-6 mm3 / Nm. The good frictional properties of the materials are a result of the self-lubricating effect.
