The tensile properties and wear resistance of SiC whisker reinforced aluminium alloy 4032 composites were investigated.
The elastic modulus of T 6 heat treated SiC/4032 composites can be expressed as
(This article is not displayable. Please see full text pdf.)
The wear loss of SiC/4032 composites decreases rapidly with an increase in the volume fraction of SiC whisker up to 14%, beyond which it remains unchanged.
The addition of BN gives rise to the degradation of the mechanical properties and also gives rise to the degradation of the coefficient of friction which improves the wear resistance of the composites.
The wear resistance of SiC/4032 composites depends remarkably on the size and distribution of Si particles of aluminium alloy 4032 matrix.
