Abstract

"ìMã PERMANENTE DE TERRAS-RARAS". Um ímã permanente de terras-raras é na forma de um corpo de ímã sinterizado que tem uma composição de liga R¬ 1¬~ a~R¬ 2¬~ b~T~ c~A~ d~F~ a~O~ f~M~ g~, em que F e R¬ 2¬ são distribuídos de maneira tal que suas concentrações aumentem na média do centro para a superfície do corpo do ímã, e os contornos de grãos com uma concentração de R¬ 2¬/ (R¬ 1¬+R¬ 2¬) que é na média maior do que a concentração de R¬ 2¬/ (R¬ 1¬+R¬ 2¬) contidos nos grãos da fase primária de um sistema tetragonal de (R¬ 1¬,R¬ 2¬) 2~ T~14~ A~ formem uma estrutura de rede tridimensional que é continua da superfície do corpo do ímã até uma profundidade de pelo menos 10 <109>m. A invenção fornece ímãs sinterizados de R-Fe-B que apresentam uma alta força coerciva.
