Notes:
Effects of solid particles on wear behavior of dispersion-hardened alloy were investigatedusing Cu-SiO2 alloys containing 0.6vol.%SiO2, 1.2vol.%SiO2 and 1.7vol.%SiO2 particles. Wear testswere made using pin-on-disc type wear machine. Wear property of the Cu-SiO2 alloys is improved byincreasing volume fraction of SiO2 particles. Moreover, wear amounts of Cu-SiO2 alloys increasewith increasing the sliding distance, and then are saturated at exceeding about 1km. This is why thatSiO2 particle improves the strength of Cu-SiO2 alloy, and that the work hardening occurs on wornsurface. Wear-induced layer is formed just below worn surface by severe plastic deformation due towear, and its hardness increases as the volume fraction of SiO2 particles increases. From theseobtained results, wear process of Cu-SiO2 alloy was discussed
