Ubushyuhe ntarengwa bwa samarium cobalt magnet ni ubuhe?

Imashini ya Samarium cobalt (SmCo) yakoreshwaga nk'uburyo bwo kubungabunga ibidukikije bikabije kubera ubushyuhe bwayo bwo hejuru. Ariko ubushyuhe ntarengwa bwa samarium cobalt ni ubuhe? Iki kibazo kiba kinini kandi cyingenzi nkumubare wibikorwa bikabije byiyongera. Ubushyuhe bwa Curie bwibikoresho bya ferromagnetiki mubisanzwe ni urugero rwo hejuru rwubushyuhe bwo gusaba. Hejuru yubushyuhe, magnet ahinduka kuva ferromagnetic imeze nka paramagnetique, kandi ntigifite imiterere ikomeye ya magneti. Kurugero, ubushyuhe bwa Curie bwa 2:17 SmCo ni 820 ° C, naho 1: 5 SmCo ni 750 ° C. Ibigize n'imiterere ya magnesi buri gihe biratandukanye, ubushyuhe bwa Curie buratandukanye gato, ariko muri rusange murirwo rwego. Nkuko Ishusho 1 yerekanwe.

Igishushanyo 1. Curie ubushyuhe bwibikoresho bya magneti bihoraho

Nyamara, mubikorwa nyabyo, magnesi ya SmCo ikunda gutakaza magnetique idasubirwaho mugihe ubushyuhe buri munsi yubushyuhe bwa Curie. Ubushuhe ntarengwa (Tmax) bwa SmCo bugarukira kubushuhe bwubushuhe bwagahato hamwe nakazi gakorwa katewe nuburyo butandukanye bwa magnesi. Niba umurongo wa BH muri quadrant ya kabiri ukoreshwa nkumurongo ugororotse nkibipimo byurubanza (Chen, JAP, 2000), Tmax ya magneti akunze gukoreshwa ya SmCo ntabwo irenga 350 ° C. Nkuko bigaragara ku gishushanyo cya 2, ibintu byiza bya magneti ya 32H ya magneti kuri 20 ° C ni Br≥11.3kGs, Hcj≥28kOe, Hk≥21kOe, na BHmax≥30.5kOe. Nyamara, coefficente yubushyuhe β (20-350 ° C) yububasha bwayo bwimbere Hcj ni 0.042%, kandi umurongo wa BH uracyagoye gukomeza umurongo ugororotse rwose muri quadrant ya kabiri kuri 350 ° C.

Igishushanyo 2, ubushyuhe bwubushyuhe bwa 32H.

Hangzhou Magnet Power Co.Ltd yashyizeho urukurikirane rwinshi rwinshi rwihanganira SmCo rukuruzi (T seri) kuva 350 ° C kugeza 550 ° C. Nkuko bigaragara ku gishushanyo cya 3, izo magneti ziva kuri T350 hamwe na Tmax ya 350 ° C kugeza kuri T550 hamwe na Tmax ya 550 ° C. Kubikorwa byihariye, nyamuneka reba kurubugahttps://www.magnetpower-tech.com/t-series-sm2co17-smco-magnet-supplier-product/.Ibikoresho bikwiranye nubushyuhe bwo hejuru nkinganda zimiti, turbine nibindi.
