Cobalt-rare earth intermetallics - suitable for mfe of permanent magnets

机译:钴稀土金属间化合物-适用于永磁磁体

摘要

Intermetallic cpds. of Co and rare earth elements have the compsns. (a) 61-64% Co, balance Sm + Pr (Pr = 10-90% RE), (b) 61-66% Co balance Sm + La (La = 10-90% RE) (c) 60-66% Co, balance Sm + Ce (Ce = 10-90% RE), and (d) 61-66% Co, balance Sm and Ce-based mischemical (mischmetal = 10-90% RE). Spec. the Pr, La, Ce and mischmetal constitute 50% RE, and are opt. substd. by up to 90% with other rare earth elements. The sintered powder comprises a major phase Co5RE with is not 35% secondary phase CoRE, and is incorporated in a suitable matrix to mfe. permanent magnets which are not easily demagnetised, suitable for a wide range of application eg. recording appts. ultrasonic wave prodn., magnetic sepn. means, car accessories etc.
