Zusammenfassung:PURPOSE:To obtain a composite material excellent in wear resistance as well as in corrosion resistance and suitable for material for cylinder, screw, etc., for extruder and injection machine in fat processing machinery. CONSTITUTION:Hard phases composed principally of borides or these borides and carbides are bound with Ni-base matrix. The composition consists, in total as a typical sample, of 2-6% B, 22-33% Cr, 7-10% Mo, 9-25% W, 3-6% Fe, 0.5-2% C, 0-2% Cu, and the balance Ni with inevitable impurities. By this method, the material excellent in wear resistance, such as adhesive wear resistance and abrasive wear resistance, as well as in corrosion resistance can be obtained.
