Investigation of the Tribological Behavior of Eutectic Al-Si Casting Alloy
<p>The effect of roughness of Al-Si alloy on the wear is investigated. Roughness average (<em>R</em><sub>a</sub>) was verified via different polishing, also was using a pin–on-disc of different loads (5, 10, 15) N, different speeds (100, 200, 300) rpm and relative humid...

| description | <p>The effect of roughness of Al-Si alloy on the wear is investigated. Roughness average (<em>R</em><sub>a</sub>) was verified via different polishing, also was using a pin–on-disc of different loads (5, 10, 15) N, different speeds (100, 200, 300) rpm and relative humidity 74%. Different values of <em>R</em><sub>a</sub> are obtained with (3, 5 and 7) µm. Worn surface were characterized using SEM / EDX. The results show that the wear rate of Al-Si eutectic alloys increases with the roughness increase. It was noticed that the specific and wear decreases as roughness decreases. Severe wear was observed at all loads.</p><p> </p><p>DOI: <a href="http://dx.doi.org/10.25130/tjes.24.2017.30">http://dx.doi.org/10.25130/tjes.24.2017.30</a></p> |
