Rolling Contact Fatigue in a Vacuum

This book deals with wear and performance testing of thin solid film lubrication and hard coatings in an ultra-high vacuum (UHV), a process which enables rapid accumulation of stress cycles compared with testing in oil at atmospheric pressure. The authors' lucid and authoritative narrative broadens readers' understanding of the benefits of UHV testing: a cleaner, shorter test is achieved in high vacuum, disturbance rejection by the deposition controller may be optimized for maximum fatigue life of the coating using rolling contact fatigue testing (RCF) in a high vacuum, and RCF testing in UHV conditions enables a faster study of deposition control parameters. In short, Rolling Contact Fatigue in a Vacuum is an indispensable resource for researchers and engineers concerned with thin film deposition, solar flat panel manufacturing, physical vapor deposition, MEMS manufacturing (for lubrication of MEMS), tribology in a range of industries, and automotive and marine wear coatings for engines and transmissions.

This book also:
