Introduction The Tribology Group in the Department of Materials Technology (formerly the Metallurgy Department) at Brunei University has been active since the late I960s. Most of the early work was on dry wear of both steels and cast irons. It was a logical development when work commenced in the middle 1970s on lubricated wear of materials. particularly those used in the internal combustion engine. This work was supported by SERC and Esso Petroleum Ltd and later Esso Chemical Ltd. During this period. two students obtained PhDs and another has recently submitted a thesis for examination. all concerned with lubricated wear of steel and cast iron engine components. It became quite clear towards the middle 1970s that other materials in both bulk form and as surface coatings would become important as the drive for lighter weight and improved fuel efficiency gathered speed.
