Esikhathini esingokwesisekelo sokwenza ugesi kanye nokusatshalaliswa kwamandla, ukukhetha kwezinto ezibalulekile ze-transformers kanye ne-inductors kudlala indima ebalulekile ekunqumeni ukusebenza kahle nokusebenza kwemishini. Izinketho ezimbili ezithandwayo zezinto ezibalulekile ziyi-AmocRous Core kanye ne-Nanocrystalline Core, ngamunye unikeza izakhiwo ezihlukile nezinzuzo. Kulesi sihloko, sizokwelulela ezimqondweni ze-amorphous Core ne-Nanocrystalline Core, futhi sihlole umehluko phakathi kwalokhu okubili.
Uyini umnyombo omnandi?
An I-Amorphous CoreUhlobo lwezinto ezibalulekile ze-magnetic ezibonakala ngesakhiwo sayo se-athomu esingeyona eye-crystalline. Lokhu kuhlelwa kwe-athomu okuhlukile kunikeza ama-amorphous cores izakhiwo zawo ezihlukile, kufaka phakathi ukulahleka okuyisisekelo okuphansi, okuphezulu okuphezulu, nezindawo ezinhle kakhulu zezinkambu. Izinto ezivame kakhulu ezisetshenziselwa ama-amorphoous Core ziyi-alloy esekwe kwinsimbi, eziqukethe izinto ezifana nensimbi, uBoron, uSiliman, ne-phosphorus.
Imvelo engeyona eye-crystalline yama-amorphous cores iphumela ekuhlelweni okungahleliwe kwama-athomu, avimbela ukwakheka kwezizinda zamabuthe futhi anciphise ukulahleka kwamanje. Lokhu kwenza ama-cores we-amorphoous asebenze kahle ngezicelo lapho ukulahlekelwa amandla aphansi kanye nokudla okuphezulu kakhulu kubalulekile, njengakumandla okusabalalisa ama-transformers kanye nama-inducmoen afudumele.
Ama-Amorphous Cores akhiqizwa kusetshenziswa inqubo esheshayo yokuqina, lapho i-alloy ebilisiwe icinywe ngesilinganiso esiphakeme kakhulu ukuvikela ukwakheka kwezinhlaka ze-crystalline. Le nqubo iholela esakhiweni se-athomu esingenayo i-oda elide, elinikeza impahla yalo eyingqayizivele.
Yini umnyombo we-nanocrystalline?
Ngakolunye uhlangothi, i-nanocrystalline Core uhlobo lwezinto ezibucayi ezibalulekile eziqukethe okusanhlamvu kwe-nanometer-sises crystalline okuhlanganisiwe ku-matrix ye-amorphous. Lesi sakhiwo sesigaba esimbaxambili sihlanganisa izinzuzo zazo zombili izinto ze-crystalline neze-amorphous, okuholela ezizameni ezinhle kakhulu zamazibuthe kanye nokugcwala okukhulu kwe-flux.
Ama-nanocrystalline coresImvamisa yenziwa ngokuhlanganiswa kwensimbi, i-nickel, kanye ne-cobalt, kanye nokungezwa okuncane kwezinye izinto ezinjengethusi ne-molybdenum. Isakhiwo se-nanocrystalline sinikezela ngentengo ephezulu kazibuthe, ukusebenzela okuphansi, kanye nokuqina okuphezulu okushisayo, okwenza kulungele izinhlelo zokusebenza ezinamandla amakhulu kanye nabaguquli abaphezulu.
Umehluko phakathi kwe-amorphous Core ne-Nanocrystalline Core
Umehluko oyinhloko phakathi kwama-amorphoous core nama-nanocrystalline cores alele ekwakhekeni kwawo kwe-athomu kanye nezakhiwo zasolwandle eziphumela. Ngenkathi ama-amorphoous cores anesakhiwo esingewona ama-crystalline ngokuphelele, ama-nanocrystalline cores abonisa isakhiwo sesigaba esimbaxambili esihlanganisa okusanhlamvu kwe-nanometer-sises ku-matrix ye-amorphous.
Ngokuya ngezakhiwo zamabuthe,ama-amorphous coresZaziwa ngokulahleka kwabo okuphansi okuphansi kanye nokubhekelwa okuphezulu, okwenza balungele izinhlelo zokusebenza lapho ukusebenza kahle kwamandla kubaluleke kakhulu. Ngakolunye uhlangothi, ama-nanocrystalline cores anikela ngokugcwala okuphezulu kwe-flux kanye nokuqina okuphezulu okushisayo, okwenza balungele izinhlelo zokusebenza ezinamandla amakhulu kanye nezicelo ezivame kakhulu.
Omunye umehluko okhiye inqubo yokukhiqiza. Ama-Amorphous Cores akhiqizwa ngokuqina okusheshayo, okubandakanya ukuqeda i-alloy ebilisiwe ngesilinganiso esiphakeme ukuvikela ukwakheka kwe-crystalline. Ngokuphambene nalokho, ama-nanocrystalline cores akhiqizwa ngokujwayelekile ngokufakwa kwe-annealing kanye nokulawulwa kwe-crystallization of izimbambo ze-amorphous, okuholela ekwakhekeni kwe-nanometer-usayizi we-crystalline okusanhlamvu ngaphakathi kokuqukethwe.
Ukucatshangelwa kohlelo lokusebenza
Lapho ukhetha phakathi kwama-amorphous cores nama-nanocrystalline cores ukuthola isicelo esithile, izici eziningana ezidinga ukubhekwa. Ngezinhlelo zokusebenza ezibeka phambili ukulahleka kwamandla okuphansi kanye nokusebenza kahle kwamandla aphezulu, njengokusetshenziswa kwamandla okusabalalisa kwamandla kanye nama-inductors afudumele aphezulu, ama-amorphoous cores avame ukukhetha okukhethwayo. Ukulahleka kwabo okuphansi okuphansi kanye nokubhekelwa okuphezulu kubenza balungele kahle lezi zinhlelo zokusebenza, zifaka isandla kulokho okulondolozwa kwamandla nokusebenza okuthuthukile.
Ngakolunye uhlangothi, ngezicelo ezidinga ukugcwala okukhulu kwe-flux, ukuqina okuphezulu okushisayo, namandla okuphatha amandla aphezulu, ama-nanocrystalline cores afaneleke kakhulu. Lezi zakhiwo zenza ama-nanocrystalline cores alungele abaguquli abanamandla amakhulu, izinhlelo ze-inverter, kanye nokuhlinzekwa kwamandla afudumele aphezulu, lapho amandla okuphatha aphezulu abucayi futhi agcine ukuqina ngaphansi kwezimo zokusebenza ezahlukene zibalulekile.
Sengiphetha, zombili ama-corephous cores nama-nanocrystalline cores anikela ngezinzuzo ezihlukile futhi ahambisana nezidingo ezithile zesicelo. Ukuqonda umehluko ngesakhiwo sabo se-athomu, izakhiwo zamabuthe, nezinqubo zokukhiqiza kubalulekile ekwenzeni izinqumo ezinolwazi lapho ukhetha izinto ezibalulekile ze-transformers kanye ne-inductor. Ngokufaka izici ezihlukile zento ngayinye, onjiniyela kanye nabaqambi bakwazi ukwandisa ukusebenza kwawo kokusatshalaliswa kwamandla nezinhlelo zokuguqula, zifaka isandla entuthukweni yokusebenza kwamandla kanye nobuchwepheshe bamandla obuyisimeme.
