Abstract

PURPOSE: To block efflorescence phenomenon of the alloy by adding additives composed of a combination of one or more kinds of Ti, V to the CaCu5 type permanent magnet alloy composed of rare earth elements including La and Co.
CONSTITUTION: In the alloy expressed by RMA (R is La or combitnation of La and one or more kinds of Sm, Ce, Pr, Nd, Y, Gd. M is Co or combination of Co and one or more kinds of Mn, Fe, Cu, Ni. 3.6≤A≤7.5), a part of M is substituted by the combination of one or more kinds of Ti, V expressed by T. Further the atom ratio of La and T is made 0.01≤T/La≤1. This permanent magnet forms the alloy of atom ratio Zr/La=0.225 at, e.g., (Sm0.2Nd0.2Pr0.06La0.4Ce0.14)(Co0.98 V0.02) through arc melting. Grinding this ingot followed by pressing and sintering in a magnetic field and quenching yields the permanent magent free from efflorescence.
