摘要：

Fe3Si, Fe3Si alloys containing Cu were fabricated by arc melting followed by hot-pressing. The friction and wear behaviors of Fe3Si based alloys with and without Cu addition against Si3N4 ball in water-lubrication were investigated. The friction coefficient and the wear rates of Fe3Si based alloys decreased as the load increased. The wear rate of Fe3Si was higher than that of AISI 304. The addition of Cu can significantly improve the friction and wear properties of Fe3Si based alloys and substantially reduce the wear rates of Si3N4 ball. The wear rate of Fe3Si-10%Cu was 2.56 x10(-6)mm(3) N-1 m(-1) at load of 20 N and decreased to 1.64 x 10(-6) mm(3) N(-1)m(-1) at load of 90 N. The wear rate of Si3N4 ball against Fe3Si-10%Cu was 1.41 x 10(-6) mm(3)N(-1) m(-1), while the wear rate of Si3N4 ball against AISI 304 was 5.20 x 10(-6) mm(3) N-1 m(-1) at load of 90 N. The wear mechanism was dominated by micro-ploughing. The combination of mechanical action (i.e., shear, smear and transference of Cu) and tribochemical reaction of Si3N4 with water was responsible for the improved tribological behavior of Fe3Si alloys containing Cu under high loads.
