Tribologische

Tribology is the science and engineering of interacting surfaces in relative motion. It studies friction, wear, and lubrication, and also considers corrosion, surface damage, and the transfer of materials. The overarching goal is to understand these processes well enough to reduce energy losses, extend component life, and improve reliability. In Dutch contexts the field is tribologie, and tribologische is the related adjective.

Friction is the resistance to motion between surfaces. Wear is the progressive removal or deformation of material. Lubrication reduces friction and wear by forming a film between surfaces, while boundary and mixed regimes involve chemical and adhesive interactions at the contact. Tribology also examines how temperature, load, speed, lubrication, and surface roughness influence outcomes.

Research methods include experimental tribometry, such as pin-on-disk and four-ball testers, to measure friction coefficients and wear rates. Surface characterization with microscopy and spectroscopy, along with computational modeling using contact mechanics and finite element methods, supports understanding of mechanisms from asperity contact to elastohydrodynamic lubrication. The Stribeck curve summarizes how lubrication regime changes with speed and viscosity.

Applications span automotive engines, gears, bearings, machining, press forming, and biomedical implants. Advances in coatings (hard coatings, diamond-like carbon, ceramics), surface texturing, and advanced lubricants (synthetic oils, bio-based lubricants) help reduce energy use and emissions, lower maintenance, and enable longer service intervals.

Ongoing challenges include tribology at the micro- and nano-scale, polymer and composite materials, high-temperature or vacuum environments, and bio-tribology. Interdisciplinary work across mechanical engineering, materials science, chemistry, and physics continues to expand the field.
