Tribology Tribology is defined as, “The science of the mechanisms of friction, lubrication, and wear of interacting surfaces that are in relative motion.” A great deal of tribological research is being conducted throughout the world in universities, and in private, government, and industrial laboratories. Virtually unheard of ten years ago, there have been thousands of Tribology papers published since 1990 and the knowledge is disseminated through many technical societies. The reliability of machines steadily improves because of this research. Herguth Laboratories, Inc. and our Research Associates are committed to maintaining our edge in tribology. Wear, or the undesirable removal of material due to relative motion, is a large consumer of materials, and shortens the life and reduces the reliability of machines. Friction and wear cost the economies of the world billions of dollars per year. Herguth Laboratories, Inc. provides Tribological services as follows: Wear Analysis • Determine mechanism of wear and solutions by examination of worn parts • Analysis of Lubricants • Wear Particle Analysis Performance Tests • Pin-on-Disk by ASTM G-99-90 • 4-ball tests by ASTM D-1583, ASTM D-2283 and ASTM D-4172 measure friction and wear of metal/lubricant combinations under boundary lubrication conditions • Pad-on-Disk • Friction • Electrical contact under hydrodynamic conditions • Ball bearing torque measurements • Fretting Corrosion tests for metal/lubricant combinations For additional information regarding Tribological capabilities and services, please contact our Research Associate, Mr. Douglas Godfrey.
