In this study, the corrosion behavior of ultra-fine Cu and SiC(p)/Cu composites
powders with different weight percentages of SiC particles was investigated in a
simulated sea solution (3.5 wt% NaCl aqueous solution). The composites were
produced via powder metallurgy (P/M) route. The corrosion performance was
evaluated by immersion tests, electrochemical measurements and SEM. The results
reveal that the corrosion performance of SiC(p)/Cu composites improved as a
function of SiC(p) content. The notable increase in corrosion resistance was
attributed to the characteristics of protective copper oxide films formed on the
surface and decreasing the microgalvanic couple between the reinforcement
particles Keywords: and Cu matrix
