Fundamentals of Friction and Vapor Phase Lubrication

摘要

This is the final report for the three year research program on 'Fundamentals of Friction and Vapor Phase Lubrication' conducted at Carnegie Mellon with support from AFOSR grant number F49630-01-1-0069. The report summarizes the program objectives and summarizes the accomplishments and progress of the research towards the development of new methods for high temperature, vapor phase lubrication (VPL), understanding the tribological properties of quasicrystalline films and the development of a fundamental understanding of friction. The three primary objectives of the work have been: Exploration of a new approach to vapor phase lubrication of ceramics by surface activation with high vapor pressure Fe containing compounds such as Fe(CO)5; Understanding the fundamental origins of friction antisotropy in crystalline metals and lubrication of metal-metal interfaces; Probing the origins of the frictional properties of quasicrystalline surfaces through comparison with quasicrystalline approximants.
