Tribologiske

Tribology is the study of friction, wear, and lubrication between surfaces in relative motion. The term tribologiske, the Norwegian form, describes phenomena, properties, or engineering practices that pertain to tribology.

Friction affects energy efficiency and heat; wear causes material loss and possible failure. Lubrication reduces friction and wear through fluid films and chemical or physical interactions. Tribological analysis considers contact mechanics, surface roughness, material pairings, and environment. Lubrication regimes include boundary, mixed, hydrodynamic, and elastohydrodynamic lubrication, each with different film thickness and interaction forces. Surface engineering and coatings, such as hard coatings and diamond-like carbon (DLC), are used to enhance tribological performance.

Measurement and analysis use tribometers to determine friction coefficients, wear rates, and contact pressure. Common tests include pin-on-disk, ball-on-flat, and four-ball tests. Wear mechanisms include adhesive, abrasive, fatigue wear, and corrosion-assisted wear, and they depend on materials, loads, speeds, and environment. Fail-safety and reliability hinge on tribological understanding.

Applications span engines, transmissions, bearings, gears, manufacturing tools, MEMS, biomedical implants, and sports equipment. Effective tribology reduces energy consumption, extends component life, lowers maintenance, and enables quieter operation. Environmental considerations drive the development of eco-friendly lubricants and advanced coatings.

Research in tribology aims to model, predict, and optimize friction and wear with computational methods, surface texturing, and novel materials. The term tribologiske is used in Norwegian-language engineering literature to discuss both fundamental science and applied design in this domain.
