Ordered qualitative test sequence, presented in flow chart form, permits identification of all common metallurgical elements and many high-temperature, stainless, high and low carbon, and tool steels within about 30 minutes. Identification is made from colors or specific reactions produced by the addition of standard chemical reagents.

The history of this relatively new topic in tribology is presented, and attention is drawn to the significant theoretical and experimental developments. The position of elastohydrodynamics in the spectrum of lubrication regimes is discussed, and the essential features of elastohydrodynamic contacts are described. Attention is focused upon film thickness calculations and measurements since this represents one of the most important and best charted fields within the subject, but friction and the distribution of pressure are also considered. Transition from hydrodynamic to elastohydrodynamic and boundary lubrication conditions is considered, and attention is drawn to the importance of the ratio of film thickness/surface roughness. A number of successful engineering applications of elastohydrodynamics are noted, and the present trends in research are outlined.
