ʻO Ferro Tungsten Magnetic?

Hiki paha i nā tungsten alloys ke hōʻike i ka magnetism e pili ana i ka metala i hoʻohui ʻia iā lākou. Hoʻohui ʻia kēia mau ʻāpana me kahi metala nui me nā ʻano mea like ʻole.

ʻO ka ʻoiaʻiʻo, hiki ke hoʻohana ʻia ka tungsten e hana i nā ʻāpana he nui i loaʻa i nā ʻano magnetic like ʻole.

No ka laʻana, ʻo ke kila tungsten ka magnetic no ka mea he kila i loko o ka hao ferromagnetic. Loaʻa i kēia ka nui o ka vanadium a me ka molybdenum me ka liʻiliʻi o 8% tungsten.

Hiki i ka tungsten carbide ke hōʻike i ka magnetism, ma muli o nā metala ʻē aʻe i hoʻohana ʻia i ke kaʻina hana. Pono ʻo Tungsten carbide i kahi metala paʻa e hui pono a ʻo ke koho ʻana o ka metala e pili ana i kona mau waiwai magnetic. Inā hoʻokomo ʻia ka cobalt a i ʻole ka hao i loko o ka alloy a laila e lilo ia i magnetic, ma ka ʻaoʻao ʻē aʻe inā hoʻohana ʻia ka nickel a laila e lilo ia i magnetic.

Nui nā mea e pili ana i nā waiwai magnetic o tungsten. Aia kēia mau kumu:

Mahana:Ke hilinaʻi nei kēia kumu i ke kānāwai o Curie e ʻōlelo ana ʻo ka hoʻohālikelike ʻana o ka mea paramagnetic i hoʻohālikelike ʻia me ka mahana. ʻO ka piʻi ʻana o ka mahana e hōʻemi i ka maʻalahi o ka magnetic, kahi e hoʻemi ai i ka pane magnetic. Loaʻa i nā haʻahaʻa haʻahaʻa ka hopena kū'ē a hoʻonui i nā waiwai magnetic o tungsten.
Hoʻohana ʻia ke kahua magnetic:Hoʻopili ke kahua magnetic i ka orientation o nā electrons ma tungsten. Hiki i ke kahua mākia ikaika ke loaʻa i nā mana magnetic nāwaliwali i ka wā e wehe ʻia ai ke kahua magnetic.
Maʻiʻo paʻa:No nā ʻāpana tungsten, hoʻohana ʻia nā mea binder e hoʻoheheʻe i nā mea like ʻole. No ka laʻana, ʻike ʻia ka cobalt i ka hoʻomaikaʻi ʻana i kēia mau waiwai, ʻoiai ka nickel i kaohi i ka hopena i kaupalena ʻia, e hoʻolilo i ka element non-magnetic.
Huina:Hoʻopili pololei ke ʻano o kēia mea i nā waiwai magnetic o ka tungsten me ka helu o nā electrons unpaired a me ke alo o nā dipoles a me kā lākou hoʻonohonoho.

Ma ke ʻano he mea metala koʻikoʻi,tungstenloaʻa i ka laulā o nā noi a me nā mea koʻikoʻi ma nā kahua o ka ʻoihana a me ka ʻepekema a me ka ʻenehana. Eia nā mea nui a me nā mea nui o ka tungsten:


1. Kiʻekiʻe-mahana alloy manufacturing
Loaʻa i ka Tungsten kahi helu heheʻe kiʻekiʻe a me nā waiwai ikaika kiʻekiʻe, e lilo ia i mea koʻikoʻi i ka hana ʻana i nā alloys kiʻekiʻe. Hoʻohana pinepine ʻia kēia mau mea wela wela i ka aerospace, aeroengines, nuklea ikehu a me nā ʻoihana kemika, a hiki ke kū i ke kiʻekiʻe kiʻekiʻe kiʻekiʻe a me ke kaomi.

2. ʻO nā mea hana ʻoki a me nā mea abrasive
Ma muli o ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana o ka tungsten, hoʻohana pinepine ʻia nā tungsten alloys i ka hana ʻana i nā mea hana ʻoki, drills, abrasives a me nā mea wili. He mea koʻikoʻi kēia mau mea hana i ka hana metala, ka mining a me nā ʻoihana ʻoihana ʻē aʻe.

3. ʻOihana uila
Hoʻohana nui ʻia ʻo Tungsten i ka ʻoihana uila e hana i nā electrodes, nā ʻūhā vacuum, nā mea uila a me nā mea semiconductor. ʻO kona wahi hoʻoheheʻe kiʻekiʻe a me kona kūpaʻa e lilo ia i mea kūpono no nā mea uila.

4. Kahua lapaʻau
Hoʻohana ʻia nā tungsten alloys e hana i nā mea lapaʻau, nā mea pale radiation a me nā lako radiotherapy. ʻO kona kiʻekiʻe kiʻekiʻe a me nā waiwai pale radiation e lilo ia i mea noi nui i ka lāʻau lapaʻau.

5. kahua ikehu nukelea
Hoʻohana nui ʻia ʻo Tungsten ma ke kahua o ka ikehu nuklea e hana i nā mea hoʻokele hopena no nā reactor nuklea a me nā mea hana nuklea ʻē aʻe. ʻO kona kiʻekiʻe kiʻekiʻe a me ka helu heheʻe e lilo ia i koho kūpono no nā mea ikehu nuklea.

6. Nā noi ʻē aʻe
Hoʻohana pū ʻia ʻo Tungsten no ka hana ʻana i nā alloys kiʻekiʻe, nā mea aerospace, nā lens optical, nā ʻāpana kaʻa, a me nā mea ʻē aʻe.


I ka pōkole, ʻo tungsten, ma ke ʻano he mea ʻenehana koʻikoʻi, loaʻa nā ʻano kino kino a me nā kemika, kahi e hana ai i kahi kuleana nui i nā kula he nui. ʻO kona paʻakikī kiʻekiʻe, wahi hoʻoheheʻe kiʻekiʻe, kūpaʻa i ka corrosion a me ke kūpaʻa dimensional e lilo ia i mea pono loa i nā ʻano ʻenehana a me nā ʻano ʻepekema. Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, e hoʻomau ka hoʻonui ʻana o ka māhele noiʻi o tungsten a hāʻawi i nā kōkua nui i ka holomua a me ka hoʻomohala ʻana o ke kaiāulu kanaka.
