Tribology deals with the design, friction, wear, and lubrication of interacting surfaces in relative motion, as bearings or gears. This definition sheds light on problems that tribological phenomena may cause in NATOs armaments, for example, systems failures and downtime repairs, supply and resupply with their costs in the permanent andor temporary loss of trained personnel, and reoccurring materials and labor costs. In general solutions to these problems include redesign of components, replacement of materials with harder andor lower friction materials, and improved lubricants. The objective of this AGARD Specialists Meeting on Tribology for Aerospace Systems was twofold 1 discuss the technology problems by having a meeting among specialists of new technologies such as coatings, lubrication and people dealing with practical problems in NATO systems airframe, engines, etc... and 2 improve the knowledge of Tribology by engineers designing or maintaining NATO systems. The scope of the Meeting was broader than aerospace because papers on reciprocating engines in land based systems were also included. It must be realized that tribological phenomena such as friction and wear are problems that will never be completely overcome by technology but can be put in remission through some of the approaches outlined here. Rain and dust erosion were not included in the Terms of Reference and should be the subject of a future AGARD activity.
