He aha ka tungsten carbide?

ʻO ka tungsten carbideis ʻike ʻia hoʻi he carbide cemented. ʻO Tungsten carbide kahi ʻano mea hoʻoheheʻe me ka tungsten (W) mea micron pauka e like me ka mea nui, ma ke ʻano ma waena o 70% -97% o ka nui o ke kaumaha, a me Cobalt (Co), Nickel (Ni), a i ʻole Molybdenum. (Mo) ka mea hoʻopaʻa.

I keia manawa, W ma ke ano oWChoʻohana nui ʻia i ka hana ʻana i ka carbide cemented.tungstenʻO ka carbide kahi mea i hana ʻia e ka hoʻopaʻa ʻana i nā ʻāpana WC hoʻokahi paʻakikī loa i loko o kahi pahu hoʻopaʻa kobalt (Co) paʻakikī e ka sintering wai. I ka wela kiʻekiʻes, WC ua hoʻoheheʻe nui ʻia i loko o ka cobalt, a hiki i ka hoʻopili ʻana i ka cobalt wai ke hana i ka WC i ka wettability maikaʻi, e alakaʻi ana i ka compactness maikaʻi a me ka hoʻolālā non-pore i ke kaʻina o ka sintering wai-phase. No laila, loaʻa i ka tungsten carbide kahi mau waiwai maikaʻi loa, e like me:

* paakiki kiʻekiʻe:Mohs’hoʻohana nui ʻia ka paʻakikī i ka hoʻohālikelike mineral. ʻO ka unahi Morse mai1i ka 10(ʻO ka nui o ka helu, ʻoi aku ka kiʻekiʻe o ka paʻakikī).ʻO ka paʻakikī o Mohs o ka tungsten carbide9 a 9.5,Hāʻawi ʻo ia i kahi pae o ka paʻakikī lua ma mua o ke daimanahe 10 ka paakiki.

*ʻaʻahu pale: ʻO ke kiʻekiʻe o ka paʻakikī, ʻoi aku ka maikaʻi o ka pale ʻana o ka tungsten carbide

* pale wela: Ma muli o kona ikaika kiʻekiʻe ma ke kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa hoʻonui hoʻonui haʻahaʻa, ʻo ia kahi mea maka maikaʻi loa no ka ʻoki ʻana i nā mea hana e hoʻohana ʻia i kahi kiʻekiʻe kiʻekiʻe a me ka wikiwiki wikiwiki.

*Ckū'ē kū'ē: ʻO Tungsten carbide kahi mea paʻa loa, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, ʻakika hydrochloric a i ʻole sulfuric acid. Eia kekahi, ʻaʻole hiki ke hana i kahi hopena paʻa me nā ʻano mea like ʻole, a hiki iā ia ke mālama i nā hiʻohiʻona paʻa a hiki i nā wahi paʻakikī.

ʻOi aku ka paʻakikī kiʻekiʻe a me ke kūpaʻa wela, ʻaʻole i hoʻololi ʻia ma 1000 ℃. Me nā pono he nui, hiki ke hoʻohana ʻia ka tungsten carbide no ka hana ʻana i nā mea hana ʻoki, nā pahi, nā mea hana wili, a me nā ʻāpana pale ʻaʻahu, a hoʻohana nui ʻia i ka ʻoihana koa, aerospace, mechanical processing, metallurgy, petroleum drilling, mining tools, electronic kamaʻilio, kūkulu, a me nā ʻoihana ʻē aʻe. ʻO ia ke kumu i kapa ʻia ai ʻo "nā niho ʻoihana".

ʻO ka tungsten carbide he 2-3 mau manawa e like me ke kila a he ikaika koʻikoʻi ma mua o nā metala hoʻoheheʻe ʻia, hoʻolei ʻia, a hoʻopaʻa ʻia. He kūpaʻa loa ia i ka deformation a mālama i kona kūpaʻa ma nā wela wela a me ke anuanu. ʻO kona kūpaʻa hopena, paʻakikī, a me ke kū'ē i ka galling/abrasions/erosions he mea kūʻokoʻa, ʻoi aku ka lōʻihi o 100 mau manawa ma mua o ke kila ma nā kūlana koʻikoʻi. ʻoi aku ka wikiwiki o ka wela ma mua o ke kila mea hana. ʻO ka tungsten carbidehiki ke hoʻolei ʻia a hoʻopau koke ʻia e hana i kahi ʻano aniani paʻakikī loa.

Me ka hooulu ana okaʻO ka ʻoihana o lalo, ke piʻi nei ka noi o ka mākeke no ka tungsten carbide. A i ka wā e hiki mai ana, ʻo ka hana ʻana i nā mea kaua kiʻekiʻe, ka holomua o ka ʻepekema a me ka ʻenehana, a me ka hoʻomohala wikiwiki ʻana o ka ikehu nuklea e hoʻonui nui i ka noi no nā huahana carbide cemented me ka ʻenehana kiʻekiʻe a me ka kiʻekiʻe.-kūpaʻa maikaʻi.
