| Abstract: | Steel Surfaces after Fricton Processes. Steel surfaces which have been treated by friction under different conditions are investigated by scanning-electron-microscopy. The well-Known differences in the treatment by either reciprocating or continuous sliding may be separated in pictures of high magnification very accurately. Liquid lubricants during boundary lubrication from layers of certain solidity on the surfaces. The addition of antiwear-additives gives a better adhesion of the layers on the substrate. The behaviour of additives containing phosphorus are investigated thoroughly and compared with competing results given in the literature. It is stated by magnified surface pictures that the original conditions of the surfaces have minor influence on the wear process. |
