It is well known that by reducing the coefficient of friction in vehicles and various types of machinery, substantial amounts of energy can be saved. We may call this – reducing the production of wasted heat through friction losses – the primary tribological energy gains. These savings are well established, relatively large in many cases, and comparatively easy to measure or estimate.
However, the role of tribology in energy saving is so much larger than this. By improving lubricants, lubricating systems, materials, surface topographies and coatings we can also reach secondary tribological energy gains. These include
• Keeping the efficiency of machinery (verkningsgraden) from deteriorating
• Improved wear life and reduced downtime (both in energy production, such as in wind mills and in all sorts of energy consuming machinery)
• New energy efficient designs of machines and components, made possible by better tribological surfaces, better lubricants, etc.
• More energy efficient manufacturing processes,
• and much more.
These roles of tribology in reducing the energy costs, in the all phases of the life cycle of materials, from material creation, product manufacturing, transportation, use, to disposal and recycling, are often totally neglected. The energy potentials here are very high in many cases!
The course will present an organised overview over the area, and present selected examples form transportation, industrial processes and power generation.
