Abstract

The objective of the present study is to evaluate AS41 alloy in adhesion wear and the effect of
carbon addition on that behavior. In the present work, experimental study has been carried out to
characterize and evaluate magnesium alloys AS41 and AS41+C.

Different techniques have been
used to investigate the microstructure, hardness and wear behavior of AS41 and AS41+C. The
dominance of a wear regime is discussed in the light of SEM micrographs of worn surfaces. The
wear experiments have been carried out under conditions of varying speed as well as varying load.
The results of this study have highlighted the wear behavior of the AS41 and AS41+C alloys
matrix composites. The results indicate that the AS41+C had the highest wear resistance followed
by the AS41 alloy under both conditions, of constant speed and increasing load. Also, the same
orders of decreasing wear resistance as that of decreasing hardness. Only the use of cheap
materials both the alloy and the reinforcement in relation to cost effective production processes for
manufacturing of magnesium based MMCs can introduce this class of low density materials for
automotive and light industries.
