Abstract
This paper, which forms part of a special issue of this journal marking
a 25th year anniversary in tribology, aims to provide an appraisal of key
issues in coating tribology over that period. Two main inter-related strands
are emphasized. One is the continuing move down the length scale in terms of
the fundamental understanding of tribological contacts. This has been
particularly useful in aiding the development of new coatings by identifying
their property requirements at different scale levels. A second strand relates
to the ongoing imperative to be able to design and select coatings to meet
practical friction and wear requirements. This selection problem requires a
robust methodology, and one such is elaborated in the paper, which takes
account of the requirements of different types of tribological contacts and
uses a combination of theoretical and empirical information. Challenges still
remain in this regard, and the paper seeks to provide a basis for further
developments to improve coatings and to ensure their effective selection.
