Abstract : A number of substances were examined for suitability under sliding conditions in the range from room temperature to 2000 F. Low melting metals applied as surface coatings show a peak in their friction at their melting points, unless they form an oxide with good lubricating ability. Pyrolytic boron nitride and graphite have the same friction and wear properties as do ordinary forms of these materials. A discussion is presented of how information may be obtained systematically from friction-temperature runs, and examples of the various techniques are given. (Author)
