Uruganda rwinshi Ibihe byose Arc neodymium magnet

Ibigize

igizwe na neodymium fer boron magnet yambaye ubusa hamwe na RTMH alloy layer yometse hejuru, aho
R ni imwe cyangwa nyinshi zatoranijwe mubintu bidasanzwe byisi Nd, Tb na Dy;
T ni Fe na / cyangwa Co;
M ni kimwe cyangwa byinshi byatoranijwe mu itsinda rigizwe na Al, Si, Ti, V, Cr, Mn, Ni, Cu, Zn, Ga, Ge, Zr, Nb, Mo, Ag, Muri, Sn, Sb, Hf , Ta, W, Pt, Au, Pb na Bi;na
H ni hydrogène;
urwego rwa RTMH rugizwe na:
Ibice 70 kugeza kuri 80 kuburemere bwa R;
Ibice 15 kugeza kuri 25 kuburemere bwa T;
Ibice 15 kugeza kuri 35 kuburemere bwa M;na
0.8 kugeza 1,2 ibice byuburemere bwa H;
igipimo kinini cya RTMH alloy layer kubijyanye nuburemere rusange bwa neodymium fer boron magnet ni 2% kugeza 3%.
