Abstract

Wear studies have been carried out by sliding A356 Al-30 wt.% SiCp metal matrix composite against steel disc at an applied pressure of 2 MPa, in the speed range of 0.5 to 10.0 m s(-1), under dry conditions. At low speeds the frictional force exhibited a periodic oscillation with time which vanished at higher speeds. Wear rate continuously decreased with increasing speed. These phenomena have been explained in terms of (a) transferred material from steel disc onto the pin surface, at low speeds, (b) increased area fraction of SiCp on the pin surface with increasing speed, (c) decreasing matrix damage with increasing speed and (d) protrusion of SiCp above the matrix at high speeds.
