Ukwakhiwa kwe-AlNiCo
Ozibuthe be-Alnicoingenye yezinto zokuqala ezithuthukiswe unomphela uzibuthe, iyingxubevange eyakhiwe nge-aluminium, nickel, i-cobalt, insimbi nezinye izakhi zensimbi. Izinto zikazibuthe ezihlala njalo ze-Alnico zathuthukiswa ngempumelelo ngeminyaka yawo-1930s. Ngaphambi kokusungulwa kwezinto ezingavamile zikazibuthe zomhlaba ezihlala unomphela ngawo-1960, ingxubevange ye-aluminium-nickel-cobalt ibilokhu iyizinto eziqinile zikazibuthe unomphela, kodwa ngenxa yokwakheka kwezinsimbi zamasu i-cobalt ne-nickel, okuholela ezindlekweni eziphakeme, ngokufika kwe Ferrite uzibuthe unomphela kanye nomhlaba ongavamile uzibuthe unomphela, izinto ze-aluminium-nickel-cobalt ezinhlelweni eziningi zishintshwa kancane kancane. Nokho, kwezinye izicelo eliphezulu lokushisa kanyehigh magneticizidingo zokuzinza, uzibuthe usabambe isikhundla esingenakunyakaziswa.
Inqubo yokukhiqiza ye-Alnico kanye nomkhiqizo
Alnico ozibuthebabe nezinqubo ezimbili zokulingisa kanye ne-sintering, futhi inqubo yokulingisa ingacutshungulwa ngosayizi nobujamo obuhlukene; Uma kuqhathaniswa nenqubo yokuphonsa, umkhiqizo we-sintered unqunyelwe usayizi omncane, ukubekezelela usayizi wento engenalutho ekhiqizwayo kungcono kunomkhiqizo ongenalutho ongenalutho, impahla kazibuthe ingaphansi kancane kuneyomkhiqizo owenziwe, kodwa umshini kangcono.
Inqubo yokukhiqiza yokuphonsa i-aluminium nickel cobalt iyaxubha → ukuncibilika → ukusakaza → ukwelashwa kokushisa → ukuhlolwa kokusebenza → ukwenza imishini → ukuhlola → ukupakisha.
I-cobalt ye-aluminium e-sintered nickel ikhiqizwa yi-powder metallurgy, inqubo yokukhiqiza ihlanganisa → ukwenza impushana → ukucindezela → ukucwilisa → ukwelashwa kokushisa → ukuhlolwa kokusebenza → ukwenza imishini → ukuhlola → ukupakisha.
Ukusebenza kwe-AlNiCo
Ukuminyana okusalayo okuguquguqukayo kazibuthe kwalesi sihloko kuphezulu, kufika ku-1.35T, kodwa ukuphoqelelwa kwawo kwangaphakathi kuphansi kakhulu, ngokuvamile kungaphansi kuka-160 kA/m, ijika layo lokususa uzibuthe alishintshile, futhi iluphu kazibuthe ye-aluminium nickel unomphela ayihlangani. nge-demagnetization curve, ngakho-ke kufanele kuqashelwe ngokukhethekile ubunjalo bayo lapho kuklanywa futhi kwenziwa isekethe kazibuthe yedivayisi. Uzibuthe waphakade kufanele uzinze kusenesikhathi. Isibonelo sengxubevange ye-anisotropic emaphakathi ye-AlNiCo, ukwakheka kwe-Alnico-6 kungu-8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, kanti okunye kungu-Fe. I-Alnico-6 ine-BHmax engu-3.9 megagauss-oesteds (MG·Oe), ukuphoqelelwa okungu-780 oersted, izinga lokushisa elingu-Curie elingu-860 °C, kanye nezinga lokushisa eliphakeme lokusebenza elingu-525 °C. Ngokusho kokuphoqeleka okuphansi kwezinto zikazibuthe ezihlala njalo ze-Al-Ni-Co, kwenqatshelwe ngokuphelele ukuthintana nanoma iyiphi impahla ye-ferromagnetic ngesikhathi sokusetshenziswa, ukuze kungabangeli ukuwohloka kwamagnetic okungenakuhlehliswa noma ukuhlanekezelwa kwendawo.i-magnetic fluxukusatshalaliswa kokuminyana.
Ukwengeza, ukuze kuqiniswe ukumelana kwayo kwe-demagnetization, ingaphezulu lesigxobo sikazibuthe esihlala njalo se-Alnickel-cobalt sivame ukuklanywa ngamakholomu amade noma izinduku ezinde, ngoba i-alnickel-cobalt unomphela uzibuthe inamandla aphansi emishini, ubulukhuni obuphezulu kanye nokuqina, okuholela. ngokusebenza kabi, ngakho-ke ayikwazi ukuklanywa njengengxenye yesakhiwo, futhi inani elincane kuphela lokugaya noma i-EDM lingacutshungulwa, futhi lifake nokunye ukucutshungulwa komshini. ayikwazi ukusetshenziswa. I-Hangzhou Magnet Power Technology Co., Ltd. inekhono lokugaya elinembayo lalo mkhiqizo, ukunemba kokucubungula kungalawulwa ngaphakathi +/-0.005 mm, futhi inekhono lokukhiqiza nekhono lokucubungula imikhiqizo emise okukhethekile, kungakhathaliseki ukuthi imikhiqizo evamile noma imikhiqizo ekhethekile emise okukhethekile, singanikeza indlela efanele nohlelo.
Izindawo zokufaka izicelo ze-Alnico
Imikhiqizo ye-cast aluminium-nickel-cobalt isetshenziswa kakhulu ekukaleni, odonsa bezinsimbi, izingxenye zezimoto, umsindo osezingeni eliphezulu, imishini yezempi kanye ne-aerospace nezinye izinkambu. I-Sintered aluminium nickel cobalt ifaneleka ukukhiqizwa kwemikhiqizo eyinkimbinkimbi, ekhanyayo, emincane, emincane, esetshenziswa kakhulu kwezokuxhumana ngogesi, izinkomishi zikazibuthe unomphela, ukushintshwa kwe-magnetoelectric nezinzwa ezihlukahlukene Imikhiqizo eminingi yezimboni nabathengi idinga ukusebenzisa omagnethi abaqinile abangapheli, njengama-motor, ukuthwebula isiginci sikagesi, imibhobho, izipikha zezinzwa, amashubhu wegagasi ahambayo, (i-cowmagnet) nokunye. Bonke basebenzisa omazibuthe be-aluminium-nickel-cobalt. Kodwa manje, imikhiqizo eminingi iyashintsha ukuze isebenzise izibuthe zomhlaba ezingavamile, ngoba lolu hlobo lwezinto lunganikeza i-Br enamandla kanye ne-BHmax ephakeme, okuvumela ivolumu yomkhiqizo omncane.
