Glancing angle X-ray diffraction, electron probe micro-analysis, scanning electron microscopy, and optical microscopy combined with sectioning and microhardness testing, have been used to identify surface layers produced on En31 (A1SI 52100) steel specimens by a series of organic disulfides and two dialkyldithiophosphates in wear tests. It is shown that the combined use of these techniques gives much more information than the use of any single one. The findings are discussed in relation to current theories of the action of extreme pressure lubricants.
