- TITLE: AN INVESTIGATION ABOUT THE EFFECT OF LOAD ON DRY SLIDING WEAR PERFORMANCE OF AA7075-T6
- ABSTRACT: Aluminum alloys are taking the place of conventional steel and other alloys owing to their high mechanical and corrosion properties. The extensive application of AA7075-T6 in the aerospace, automotive and structure industries is due to its high strength-to-weight ratio, low corrosion potential and high machining properties and therefor requires detailed investigation. Frictional behavior of AA7075-T6 against ball for low loads (3N, 5N and 7N) was investigated to characterize the worn surface in terms of wear rate and coefficient of friction (COF) using a pin-on- disc tribometer. Microstructural composition was depicted with optical microscope (OM). Wear rate and COF values were investigated accordance with different low test loads. A detailed tribological characterization was carried out using scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX) and wear track profiles were observed. In the AA7075-T6 alloy present phases were determined using X-ray diffractometer (XRD) analysis. Morphological characterizations were accomplished by SEM and wear mechanisms were examined.32 OAl
