Sinterlenmi\u015f NdFeB, en eski haz\u0131rlama prosesi ve evrensel olarak en yayg\u0131n olarak uygulanabilirli\u011fi sayesinde nadir toprak kal\u0131c\u0131 m\u0131knat\u0131s malzemelerinin h\u0131zla geli\u015fmesini sa\u011flam\u0131\u015ft\u0131r. G\u00fc\u00e7l\u00fc manyetik anizotropisi ve d\u00fc\u015f\u00fck maliyetli hammadde girdisi ile sinterlenmi\u015f NdFeB, bir\u00e7ok \u00fclke i\u00e7in bir ara\u015ft\u0131rma hedefi haline gelmi\u015ftir. Sinterlenmi\u015f NdFeB kal\u0131c\u0131 m\u0131knat\u0131s malzemeleri, toz metalurjisinden yararlan\u0131r. Eritilmi\u015f ala\u015f\u0131m toz haline getirilir ve manyetik alanda s\u0131k\u0131\u015ft\u0131r\u0131lm\u0131\u015f bir yap\u0131ya preslenir. S\u0131k\u0131\u015ft\u0131r\u0131lm\u0131\u015f yap\u0131 daha sonra yo\u011funla\u015ft\u0131rma sa\u011flamak i\u00e7in inert gaz veya vakumda sinterlenir. Ayr\u0131ca, m\u0131knat\u0131s\u0131n koersivitesini art\u0131rmak i\u00e7in genellikle ya\u015fland\u0131rma \u0131s\u0131l i\u015flemi gerekir. \u0130\u015flem ak\u0131\u015f\u0131 \u015fu \u015fekildedir: hammadde haz\u0131rlama \u2192 eritme \u2192 toz haz\u0131rlama \u2192 presleme \u2192 sinterleme ve temperleme \u2192 manyetik test \u2192 ta\u015flama \u2192 i\u015fleme \u2192 elektrokaplama \u2192 bitmi\u015f \u00fcr\u00fcn.<\/p>\n
Sinterlenmi\u015f NdFeB’nin aksine, ba\u011fl\u0131 m\u0131knat\u0131slar\u0131n her bir toz partik\u00fcl\u00fcn\u00fcn yeterince y\u00fcksek bir s\u0131k\u0131\u015ft\u0131r\u0131lm\u0131\u015f yap\u0131ya sahip olmas\u0131 gerekir. Toz haz\u0131rlama i\u015flemi s\u0131ras\u0131nda y\u00fcksek koersivite i\u00e7in gereken \u00e7ok fazl\u0131 yap\u0131 ve mikro yap\u0131 ciddi \u015fekilde hasar g\u00f6rd\u00fc\u011f\u00fcnde, iyi ba\u011flanm\u0131\u015f m\u0131knat\u0131slar \u00fcretmek imkans\u0131z hale gelir. Bu nedenle, h\u0131zl\u0131 s\u00f6nd\u00fcren manyetik tozu eriterek d\u00f6nd\u00fcrme y\u00f6ntemi kullan\u0131larak, s\u0131cak erimi\u015f ala\u015f\u0131m \u00f6nce y\u00fcksek h\u0131zl\u0131 d\u00f6nen, su so\u011futmal\u0131 bir bak\u0131r tekerle\u011fe d\u00f6k\u00fcl\u00fcr veya p\u00fcsk\u00fcrt\u00fcl\u00fcr ve 100 \u03bcm kal\u0131nl\u0131\u011f\u0131nda ince bir \u015ferit olu\u015fturulur.<\/p>\n

A\u015f\u0131r\u0131 s\u00f6nd\u00fcrme (h\u0131zl\u0131 so\u011futma) ko\u015fullar\u0131 kullan\u0131larak daha ince taneler veya hatta amorf manyetik toz elde edilir.

Daimi M\u0131knat\u0131sl\u0131 Motorlar<\/p>\n
Daimi m\u0131knat\u0131sl\u0131 motorlarda, uyarma i\u00e7in kal\u0131c\u0131 m\u0131knat\u0131slar\u0131n kullan\u0131lmas\u0131 yaln\u0131zca g\u00fc\u00e7 t\u00fcketimini azalt\u0131p enerji tasarrufu sa\u011flamakla kalmaz, ayn\u0131 zamanda motor performans\u0131n\u0131 da art\u0131r\u0131r.<\/p>\n
Manyetik Makineler<\/p>\n
Manyetik makineler, m\u0131knat\u0131slardaki benzer kutuplar\u0131n itme kuvvetini veya farkl\u0131 kutuplar\u0131n \u00e7ekme kuvvetini kullanarak \u00e7al\u0131\u015f\u0131r. Bu, y\u00fcksek kal\u0131c\u0131 m\u0131knat\u0131slanma ve y\u00fcksek i\u00e7sel zorlay\u0131c\u0131l\u0131\u011fa sahip kal\u0131c\u0131 m\u0131knat\u0131slar gerektirir. Ayr\u0131ca, farkl\u0131 kutuplar aras\u0131ndaki \u00e7ekim prensibi sayesinde, temass\u0131z iletim kullan\u0131larak manyetik s\u00fcr\u00fcc\u00fcler \u00fcretilebilir ve s\u00fcrt\u00fcnme ve g\u00fcr\u00fclt\u00fc gibi avantajlar sunar. Bu nedenle, y\u00fcksek performansl\u0131 Nd-Fe-B m\u0131knat\u0131slar, madencilik makinelerinin tahrik bile\u015fenlerinde, uydu ve uzay ara\u00e7lar\u0131ndaki jiroskop ve t\u00fcrbinlerdeki manyetik yataklarda ve t\u0131bbi ekipmanlarda kalp fonksiyonunu desteklemek i\u00e7in santrif\u00fcj pompalardaki rotor yataklar\u0131nda yayg\u0131n olarak kullan\u0131lmaktad\u0131r.<\/p>\n

Nadir toprak kal\u0131c\u0131 m\u0131knat\u0131s malzemeleri, roket f\u0131rlatmalar\u0131, uydu konumland\u0131rma ve ileti\u015fim teknolojileri i\u00e7in vazge\u00e7ilmezdir. Y\u00fcksek performansl\u0131 sinterlenmi\u015f Nd-Fe-B, \u00f6zellikle radar i\u00e7in mikrodalga verici\/al\u0131c\u0131 sistemlerinde kullan\u0131\u015fl\u0131d\u0131r. Sabit bir manyetik alan ve alternatif bir mikrodalga manyetik alan\u0131n\u0131n birle\u015fik etkisinden yararlan\u0131larak ferromanyetik rezonans olu\u015fur ve bu da mikrodalga sirk\u00fclat\u00f6rleri, izolat\u00f6rler vb. \u00fcretimine olanak tan\u0131r. T\u00fcketici Elektroni\u011fi<\/p>\n
3C t\u00fcketici elektroni\u011fi, sinterlenmi\u015f NdFeB i\u00e7in her zaman \u00f6nemli bir alt sekt\u00f6r olmu\u015ftur. Sinterlenmi\u015f NdFeB, 3C t\u00fcketici elektroni\u011fi \u00fcr\u00fcnlerindeki minyat\u00fcrle\u015ftirme, hafifletme ve inceltme trendleriyle uyumlu y\u00fcksek manyetik enerjili \u00fcr\u00fcn gibi \u00f6zelliklere sahiptir. VCM’ler, cep telefonu lineer motorlar\u0131, kameralar, kulakl\u0131klar, hoparl\u00f6rler ve mil tahrikli motorlar gibi elektronik bile\u015fenlerde yayg\u0131n olarak kullan\u0131l\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
