| Popis: | Fretting wear resulting from micro-displacement oscillatory movements is considered a serious impediment to many industrial applications like gears, turbo engines, etc. Large conformal contact configurations of industrial components are very complicated to reproduce at laboratory scale. As a result, simple non-conformal contact geometries including sphere-on-flat and cylinder-on-flat are usually adopted in research laboratories. Yet, few are the researches that examined fretting wear using flat-on-flat geometry due to its high sensitivity to alignment issues although this contact configuration allows the analysis of quasi-constant pressure condition. In the current study, fretting wear of flat-on-flat dry contact made of a steel alloy (35NCD16) is investigated experimentally by varying several parameters including test duration, contact pressure, sliding amplitude and frequency. A power law formulation is introduced providing reliable prediction of the wear rate. The analysis of test results confirms a high dependency of the wear kinetics on the loading condition regarding the transition from abrasive to adhesive wear. |
