Wear and friction behaviour of alumina thin coatings prepared by sol-gel methods
Journal Title: Tribologia - Year 2011, Vol 235, Issue 1
Abstract
In this study, alumina coatings were prepared by the sol-gel method using the dip-coating technique. All samples were prepared on silicon wafers Si (100) with the use of aluminium sec-butoxide as a precursor. The surface topographies of alumina coatings were imaged by an atomic force microscope (AFM). Tribological properties were characterised using a microtribometer and an optical microscope. The results show a strong dependence of antiwear and antifrictional properties of alumina coatings on the annealing temperatures. The best performance was exhibited by coatings heated to 1000°C due to the formation of hard α-Al2O3.<br/><br/>
