Investigation of wear and adhesion properties of different oxide coatings grown on Al2024 base material

Aluminum alloys are widely used in many engineering fields such as automotive, medicine and aviation today due to their low density, corrosion resistance and high mechanical properties. The use of these alloys is limited due to their advantages and disadvantages. Many studies are being carried out to turn these disadvantages into advantages. Studies on surface modification processes to increase wear and corrosion resistance have increased in recent years. This study focused on the micro arc oxidation (MAO) process. MAO method is an electrochemical surface coating process. Although it is an environmentally friendly method, its relatively low cost compared to other methods makes the MAO method more attractive. In the literature review, it was seen that studies on the effect of ZnO and MoS2 added oxide coatings grown by the MAO method on the wear and adhesion properties of Al2024 alloy are limited. In this thesis study, the chemical composition, microstructure and phase structure of the coated samples will be determined by Energy dispersive X-ray Spectroscopy (EDS), Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD), respectively. The adhesion resistance of these coatings with Al2024 will also be determined with the Scratch Test device. Tribological properties will be examined with the TRD tribometer device and a relationship will be established between the created coatings.
