Description of Surface Topography of Metal Matrix Composite Castings

Abstract

The paper presents studies of topography of the metal matrix composite castings using profilography, confocal microscopy and atomic force microscopy. The examined materials were composites from the ex-situ group, manufactured by the saturation of reinforcement (aluminosilicate or carbon) with the liquid aluminum alloy (AlSi9 or AlSi11). The materials were observed on the various surface state, resulting from different stages of preparation of the polished section for the metallographic between the composite matrix and reinforcement
