摘要: Abstract An integrated approach employing semiquantitative Auger electron spectroscopy (AES) depth profile analysis and mechanical wear in a Reichert cylinder-on-disc machine was applied to the study of worn surfaces under heavy load conditions presence extreme pressure (EP) additives. A significant correlation between sulphur content topmost reaction layer behaviour observed, although were not ideal for AES analysis. repeatability better than 10% obtained on basis four independent measurements. The thickness sulphur- phosphorus-rich surface formed EP additives is much smaller that so-called white produced by deformation high local temperature. observed wear-preventive action sulphur-rich possibility characterizing this offer interesting approaches mechanism prevention
