Experts estimate that in 1978 alone over 4.22 × 1018 joule of energy were lost in the United States due to simple friction and wear — enough energy to supply New York City for the entire year. Energy loss through friction in tribo-elements is a major factor in limits on energy efficiency [1]. The two major approaches that have been pursued in the past for reducing frictional losses in tribological contacts were surface modification techniques such as laser texturing and modification of lubricant properties. Here we advocate yet another option, modification of the structural character of the lubricant film. The Composite-Film bearing (CFB) is investigating this third possibility.
