| Summary: | 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.
