Välkommen till kurswebben!

Alla kurser på KTH använder inte kurswebben fullt ut i dagsläget. Kurswebben är däremot alltid öppen för studenter. Som student kan bidra med material i kurswikin ( t ex föreläsningsanteckningar och lästips), ställa frågor och diskutera kursen med andra studenter. Modereringsfunktionen fångar upp obesvarade frågor till myndigheten KTH och skickar dem vidare till rätt instans. På kurswebben hittar du även schemainformation om kursen.

Tribology is the science of friction, wear and lubrication or the design technology for interacting surfaces in relative motion. We are all daily affected by different tribological phenomena. Leaf on the railway track reduces the friction between railway wheel and rail and causes delay in the train traffic. The squealing noise when we brake a car is caused by friction between discs and pads in the brakes. Wear particles generated from brakes and from the road wheel contact are a health problem in urban environment. Worn hip joints is another example of tribological challenges.

The word tribology is derived from the Greek word tribos meaning rubbing. This word was coined in 1966 by Peter Jost, UK. Although, tribological knowledge was already used thousands of years before our century, for example, to transport monuments in Egypt by using natural lubricants to reduce friction.
