tribologist

By comparing the OA results of new and used oil, a tribologist can determine when an oil must be replaced.

Another engineer at Rensselaer, Salvadore J. Calabrese, is a tribologist who has made a special study of microscopic surface patterns on materials that slide against each other.

"We realized at the beginning that a piano key must be smooth but not slippery," Dr. Scarton said, "and that the problem had to be attacked from the viewpoint of the tribologist, an engineer expert in friction."

Michell/Kingsbury fluid dynamic tilting-pad bearings were invented independently and almost simultaneously by both British-born Australian, Anthony George Maldon Michell and American tribologist Albert Kingsbury.
