Wear of unlubricated steel surfaces.
Kirkpatrick, Donald M.

An investigation was made of the wear, under varying conditions of load and speed, of an annealed steel finger held against a rotating hardened steel sleeve. Measurement of the wear was made by weight and volume change of the finger, whereas measurement of the transfer to the sleeve was made by its increase in weight or, on separate runs, by its increase in radioactivity. The atmosphere was dry air. The purpose of this work was to inspect an elementary wear process and accompanying transfer of metal under simple controlled conditions with a view to separating out the various component processes which are collectively known as wear. By this process it is hoped to determine more of the "why" of wear. This was done by a previously accomplished radioactive technique and also by a corroborative weight change technique.
