Ndeipi inogumira tembiricha yesamarium cobalt magineti?

Iyo Samarium cobalt magineti (SmCo) yaiwanzo shandiswa senge sarudzo kune yakanyanyisa nharaunda nekuda kwayo kwepamusoro-tembiricha kuramba.Asi chii chinogumira tembiricha yesamarium cobalt?Uyu mubvunzo unowedzera kukosha sezvo huwandu hwenzvimbo dzekushandisa zvakanyanya hunowedzera.Iyo Curie tembiricha yeferromagnetic zvinhu kazhinji ndiyo yekumusoro muganho wekushisa kwekushandisa.Pamusoro pe tembiricha iyi, magineti anochinja kubva pa ferromagnetic state kuenda pa paramagnetic state, uye haasisina simba remagineti maitiro.Semuenzaniso, tembiricha yeCurie ye2:17 SmCo ingangoita 820°C, uye iyo ye1:5 SmCo inenge 750°C.Kuumbwa uye chimiro chemagineti chinogara chakasiyana, tembiricha yeCurie yakati siyanei, asi kazhinji iri mumhando iyi.Sezvakaratidzwa Mufananidzo 1.

Mufananidzo 1. Curie tembiricha yezvakasiyana zvisingaperi magineti zvinhu

Nekudaro, mumashandisirwo chaiwo, magineti eSmCo anowanzo kurasikirwa nemagineti isingachinjike kana tembiricha yakadzikira kupfuura tembiricha yeCurie.Iyo yakanyanya tembiricha (Tmax) yeSmCo inoganhurwa neiyo tembiricha coefficient ye coercivity uye nzvimbo yekushanda inokonzerwa nemhando dzakasiyana dzemagineti.Kana iyo BH curve muchikamu chechipiri ichishandiswa semutsetse wakatwasuka seyero yekutonga (Chen, JAP, 2000), iyo Tmax yeanowanzo shandiswa SmCo magineti haipfuure 350 ° C.Sezvinoratidzwa mumufananidzo 2, iyo yakanakisa magineti maitiro e32H magineti pa20 °C ndeye Br≥11.3kGs, Hcj≥28kOe, Hk≥21kOe, uye BHmax≥30.5kOe.Zvakadaro, tembiricha coefficient β (20-350 °C) yemukati yekumanikidza kwayo Hcj ndeye 0.042%, uye yayo BH curve ichiri kunetsa kuchengetedza mhedziso yakatwasuka muchikamu chechipiri pa350 °C.

Mufananidzo 2, tembiricha curve ye32H.

Hangzhou Magnet Power Co.Ltd yakagadzira nhevedzano yepamusoro tembiricha inodzivirira SmCo magineti (T akatevedzana) kubva pa350 °C kusvika 550 °C.Sezvinoratidzwa muMufananidzo 3, magineti aya anobva paT350 ane Tmax ye350 °C kusvika paT550 ine Tmax ye550 °C.Nekuita kwakananga, ndapota tarisa kune webhusaiti linkhttps://www.magnetpower-tech.com/t-series-sm2co17-smco-magnet-supplier-product/.Ichi chinyorwa chinokodzera kushandiswa kwekushisa kwakanyanya semakemikari indasitiri, turbine nezvimwe zvakadaro.
