Abstract

Cu-xTiC (x=0, 1, 5, 10 and 15
wt.%) composites were prepared by hot pressing (HP) technique. The
microstructure, corrosion and wear features of Cu matrix composites (CMCs) were
investigated. The wear surfaces and microstructure of the CMCs were analyzed
using SEM-EDS. Phases of samples were identified by means of XRD. Hardness
measurements of the composites were made using a microhardness device. Hardness
tests showed that the hardness tends to increase with increasing TiC amount. Wear
properties of the CMCs were determined using ball-on-disc method. Significant
decreases in wear rates were observed in composites reinforced with TiC. The corrosion
properties of the composites were characterized by potentiostatic polarization
test. Corrosion results showed that the corrosion resistance of the composites
decreased with the increase of TiC content in Cu. Among the composites, Cu-1% TiC has the best
corrosion resistance.
