A comparative study has been made on the wear behavior of eutectic Al-Si automotive alloy under a dry, fresh and used engine oil sliding environment. The wear tests have been conducted using a standard pin-on-disc apparatus. The results show that with silicon content, the wear loss decreases up to t...
