概要

論文の詳細を見る
In the previous instalment the authors demonstrated the importance of the influence of heat conductivity of guide materials upon the effect of wax transfer. The present instalment concerns the transfer phenomenon on guidess having very thin layers of heat conductivity which differs from that of bulk materials.<BR> Three kinds of materials enamelled copper, enamelled iron, and chromium evaporation-coated glass — have been tested.<BR> The wear-time curve of enamelled copper has been shown to be linear with irregular fluctuations and that of enamelled iron to be a saturation curve also with random variations. <BR> Optical micrographs of the sliding surface have shown that no macroscopic transfer takes place on enamelled copper and a slight transfer on enamelled iron. The chromium layer on glass is very thin and wears out rapidly. However, photomicrographs show that cotton wax is transferred onto a chromium surface due to the low heat-conductivity of glass.<BR> These results prove again the importance of the influence of heat conductivity of guide materials on the wear mechanism.
