Abstrakt: | The paper presents an estimation of the usefulness modification of anodic oxide coatings (AHC) on aluminium alloys with molybdenum disulfide (MoS2) for the improvement of the tribological properties of Al2O3 coatings. Anodic oxide coatings were produced through hard anodising on the EN AW-5251 aluminium alloy in a multi-component electrolyte modified with molybdenum disulfide powder with a grain size below 20 micrometers (concentration of MoS2 powder in electrolyte: 0–80 g/l). Tribological tests of modified AHC were conducted in a surface-surface couple in reciprocating motion at the T-17 research stand simulating the conditions of piston/sealing contact of lubricant-free pneumatic servo-motors. The obtained results indicate a significant reduction of the friction coefficient of a sliding couple consisting of a polymer (PEEK/BG material) and an anodic oxide coating, as well as a reduction of wear of the polymer tribopartner as a result of the modification of the oxide coating with MoS2 (especially in the presence 60 g/l of MoS2 powder in electrolyte). The effect of the modification of anodic oxide coatings with molybdenum disulfide is also a significant reduction of the time of wearing-in of the tested couple. |
