INFLUENCE OF LUBRICANT OIL COMPONENTS ON THE CHARACTER OF FRICTION PROCESSES OCCURRING ON WC/C-COATED SURFACE
Journal Title: Tribologia - Year 2013, Vol 252, Issue 6
Abstract
Wear and scuffing resistance of steel elements (100Cr6) coated with WC/C (a-C:H:W type) in lubricated frictional couple were investigated. Poli-a-olefin oil (PAO-8) containing 0,1–1,0% v/v AW or EP additive and 2% v/v different fatty acid esters was used as a lubricant. After tribological tests the structure of the external layer (inside and outside wear scars) was investigated. Results indicate that common commercial AW/EP additives added in small concentration (0,2%) improve antiwear efficiency of PAO-8. At this concentration the AW additive increased the wear resistance of WC/C-coated elements. Synergism between antiwear action of AW additive and fatty acid esters (used as ecological additive) also was observed. The obtained results represent guidelines on blending lubricants designed for WC/C coatings.
