Dry sliding wear behaviour of A390 hypereutectic (Al–Si) alloy

Abstract

The behavior of wear for dry alloy A390 of (aluminum–silicon) casting which constitutes 16% Si is investigated. The lost of the wear rate is weighted and the volume decreases with increasing speed of sliding as well as the passage of sliding time. The coefficient of friction decreases as sliding speed increases reaching to the steady state. It is focused to be applicable under high temperatures for pistons and cylinders using the pin on disc for different slide speed and time.
