摘要

Experimental study was undertaken on copper matrix composites (CMCs) added with varying weight percentages of SiC and TiC fragments by powder metallurgy (PM) technique. Cylindrical specimen of pure Cu and composites of Cu-2.5wt.%SiC-2.5wt.%TiC, Cu-2.5wt.%SiC-7.5wt.%TiC, Cu-2.5wt.%SiC-12.5wt.%TiC, Cu-2.5wt.%TiC-7.5wt.%SiC and Cu-2.5wt.%TiC-12.5wt.%SiC were processed in a 400 kN hydraulic press and sintered for four hours at 900 °C in a box furnace. The even distributions of reinforcements SiC and TiC in the matrix were confirmed using scanning electron microscope (SEM). SiC and TiC were confirmed to be present in the Cu matrix by the EDAX study. The sintered samples' mechanical characteristics and corrosion behavior were examined. Result shows that the inclusion of SiC and TiC increases the mechanical characteristics of Cu-SiC-TiC specimen. Salt spray corrosion test revealed an improved corrosion resistance, and a least value 0.000151505 mm/year was found on Cu-2.5wt.%TiC-12.5wt.%SiC composite. Maximum compressive strength of 698 MPa was noted on the sample containing Cu-2.5wt.%SiC-7.5wt.%TiC. Enhancement in porosity and decline in density were observed with the improvement in wt.% of SiC and TiC to Cu matrix. All sintered specimens were found having higher density than that of green condition.
