ʻO Tungsten Carbide-Nickel He Magnetic a ʻAʻole Magnetic?

ʻO Tungsten carbide, i kapa ʻia ʻo carbide cemented, i haku ʻia me ka pauka tungsten carbide a me ka pauka binder. Hiki i ka pauka hoʻopaʻa ʻia ke pauka cobalt a i ʻole ka pauka nickel. Ke hoʻohana nei mākou i ka pauka cobalt ma ke ʻano he mea hoʻopaʻa i ka hana ʻana i nā huahana tungsten carbide, e loaʻa iā mākou kahi hoʻāʻo kobalt magnetic e nānā i ka nui o ka cobalt i ka tungsten carbide. No laila ʻoiaʻiʻo he magnetic ka tungsten carbide-cobalt. Eia naʻe, ʻaʻole magnetic ka tungsten carbide-nickel.

Manaʻo paha ʻoe he mea hiki ʻole ke hilinaʻi i ka hoʻomaka. Aka, he oiaio. ʻO Tungsten carbide-nickel kahi ʻano mea non-magnetic me ke kūpaʻa hopena maikaʻi. Ma kēia ʻatikala, makemake wau e wehewehe i kēia iā ʻoe.

E like me nā metala i hoʻomaʻemaʻe ʻia, ʻo ka cobalt a me ka nickel he magnetic. Ma hope o ka hui ʻana, kaomi ʻana, a me ka sintering me ka pauka tungsten carbide, paʻa mau ka tungsten carbide-cobalt, akā ʻaʻole ka tungsten carbide-nickel. ʻO kēia no ka mea e komo nā ʻātoma tungsten i ka lattice o ka nickel a hoʻololi i nā milo electron o nickel. A laila hiki ke hoʻopau ʻia nā wili electron o ka tungsten carbide. No laila, ʻaʻole hiki ke huki ʻia ka tungsten carbide-nickel e kahi magnet. I ko mākou ola i kēlā me kēia lā, pili pū ke kila kila i kēia kumu.

He aha ka electron spin? ʻO ka milo uila kekahi o nā ʻano waiwai ʻekolu o nā electrons. ʻO nā waiwai ʻē aʻe ʻelua ka nuipa a me ka uku o ka electron.

ʻO ka hapa nui o nā mea i haku ʻia me nā molekala, nā molekala i nā ʻātoma, a me nā ʻātoma i haku ʻia me nā nuclei a me nā electrons. I loko o nā ʻātoma, ke wili mau nei nā electrons a puni ka nucleus. Hiki i kēia mau neʻe o nā electrons ke hana i ka magnetism. I kekahi mau mea, neʻe nā electrons i nā ʻaoʻao like ʻole, a hiki i nā hopena magnetic ke hoʻopau i ka mea i ʻole kēia mau mea ma lalo o nā kūlana maʻamau.

Eia naʻe, ʻokoʻa kekahi mau mea ferromagnetic e like me ka hao, cobalt, nickel, a i ʻole ferrite. Hiki ke hoʻonohonoho ʻia kā lākou mau wili electron ma kahi liʻiliʻi e hana i kahi domain magnetic. ʻO ia ke kumu i hoʻomaʻemaʻe ʻia ai ka cobalt a me ka nickel a hiki ke huki ʻia e kahi magnet.

I ka tungsten carbide-nickel, pili ka tungsten atoms i ka electron spins of nickel, no laila ʻaʻole magnetic hou ka tungsten carbide-nickel.

Wahi a nā hopena ʻepekema he nui, ʻoi aku ka kiʻekiʻe o ka tungsten carbide-nickel i ke kūpaʻa corrosion a me ke kūpaʻa oxidation ma mua o ka tungsten carbide-cobalt. I ka sintering, hiki i ka nickel ke hana i kahi wai wai maʻalahi, hiki ke hāʻawi i ka hiki ke hoʻomaʻemaʻe maikaʻi ma luna o ka tungsten carbide surfaces. ʻO ka mea hou aku, ʻoi aku ka haʻahaʻa o ka nickel ma mua o ka cobalt.

Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
