- Modifying the microstructural, topographical, or compositional properties of a surface to improve friction, wear resistance, lubrication conditions, or corrosion resistance.
- Studying the fundamentals of fluid film lubrication, hydrodynamic lubrication, and elastohydrodynamic lubrication.
- The science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear.
- Materials science, also commonly known as materials engineering, is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This relatively new scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry.
