ʻO Carbide he metala paʻakikī loa, ʻelua wale nō i ka daimana ma ka paʻakikī a ʻoi aku ka paʻakikī ma mua o ka hao a me ke kila kila.I ka manawa like, ua like ke kaumaha me ke gula a ʻoi aku ka paʻakikī o ka hao.Eia kekahi, loaʻa iā ia ka ikaika maikaʻi a me ka elasticity, hiki ke mālama i ka paʻakikī i nā mahana kiʻekiʻe, a ʻaʻole maʻalahi ke komo.No laila, hoʻohana pinepine ʻia nā mea carbide i nā māla hana ʻoihana e like me nā mea hana metala a me nā mold.

Mahele ʻEkahi: He aha nā mea carbide?
Hana ʻia ka carbide cemented me ka tungsten carbide a me ka cobalt.ʻO Tungsten carbide kahi mea me kahi kiʻekiʻe heheʻe.Pono e hoʻoheheʻe ʻia i ka pauka a laila hana ʻia e ka wela wela a me ka paʻa, a hoʻohui ʻia ka cobalt ma ke ʻano he mea paʻa.Hele mai ʻo Tungsten mai Kina, Rūsia a me South Korea, aʻo ka cobalt mai Finland, Kanada, Australia a me Kongo.No laila, ka hana ʻana i nā alloys superhard e koi i ka hui honua e hoʻopili i kēia mea kupanaha i nā ʻano ʻano like ʻole. titanium-cobalt (niobium).ʻO ka mea i hoʻohana nui ʻia i ka hana ʻana he tungsten-cobalt a me tungsten-titanium-cobalt cemented carbide.
I mea e hana ai i ka paʻakikī paʻakikī, pono ia e wili i ka tungsten carbide a me ka cobalt i loko o ka pauka maikaʻi, a puhi a paʻa i ka wela kiʻekiʻe (1300 ° C a 1500 ° C) e hoʻopaʻa i ka mea.Hoʻohui ʻia ʻo Cobalt ma ke ʻano he mea hoʻopaʻa e kōkua i nā ʻāpana tungsten carbide e pili kekahi i kekahi.ʻO ka hopena he metala paʻa loa me kahi helu heheʻe o 2900 ° C, e hana ana i ke kūpaʻa i nā wela kiʻekiʻe a kūpono no nā noi wela kiʻekiʻe.
Mahele ʻElua: He aha ka hoʻohana ʻana i nā mea carbide?
Loaʻa i ka carbide Cemented ka laulā o nā noi.Ma ke kahua o ka hana ʻoihana, hoʻohana nui ʻia i ka hana ʻana i nā mea ʻokiʻoki no ka hana metala e like me nā mea hoʻoheheʻe CNC, nā mīkini milling CNC, a me nā lathes CNC.Eia kekahi, hiki ke hoʻohana ʻia e hana i nā ʻāpana no nā kini alumini e like me ke kofe canned a me nā mea inu, nā ʻāpana hoʻoheheʻe pauka no nā ʻāpana mīkini kaʻa (sintered parts), a me nā ʻāpana no nā mea uila e like me nā kelepona paʻa.
Ma ke ʻano o ka hana ʻana a me ka hoʻoili ʻana, ʻike ʻia ke koʻikoʻi o ka alloy super hard.Ma muli o kona paʻakikī maikaʻi loa a me ka ikaika, hoʻohana nui ʻia nā alloys superhard i nā mea mīkini e like me nā mea ʻoki metala, nā mea hana wili, nā mīkini wili a me nā lathe.Eia kekahi, hiki ke hoʻohana ʻia e hana i ka alumini hiki ke hoʻoheheʻe ʻia no ke kofe canned a me nā mea inu, ka pauka hoʻoheheʻe ʻia no nā ʻāpana ʻenekini kaʻa (sintered parts), a me nā ʻāpana no nā mea uila e like me nā kelepona paʻalima, etc.
Eia nō naʻe, ʻaʻole i kaupalena ʻia nā alloys superhard i ke kahua o ka hana metala a me ka hana ʻana.Hiki ke hoʻohana ʻia no ka ʻoki ʻana i nā pōhaku paʻakikī, e like me ke kūkulu ʻana i nā tunnels pale, a me ka ʻoki ʻana i nā alanui asphalt a me nā māla ʻē aʻe.Eia kekahi, ma muli o kāna mau hiʻohiʻona maikaʻi loa, hiki ke hoʻohana nui ʻia nā alloys superhard i nā kula ʻē aʻe no ka mīkini CNC.No ka laʻana, nā mea hana ʻokiʻoki i hoʻohana ʻia i ka lāʻau lapaʻau, nā pōkā a me nā poʻo kaua i ke kahua kaua, nā ʻāpana ʻenekini a me nā lau turbine mokulele i ke kahua aerospace, etc.
Ma waho aʻe o ka hoʻohana ʻana i ka ʻoihana, pāʻani pū kekahi i nā alloys paʻakikī loa ma ke kahua o ka noiʻi ʻepekema.No ka laʻana, hiki ke hoʻohana ʻia e hana i nā lāʻau diffraction i ka X-ray a me ka noiʻi optical, a ma ke ʻano he catalyst i ke aʻo ʻana i nā hopena kemika.
Mahele ʻEkolu: He aha ka paʻakikī o ka mīkini ʻāpana carbide?
ʻAʻole maʻalahi ka hana ʻana o ka carbide cemented a he nui nā pilikia.ʻO ka mea mua, ma muli o kona paʻakikī kiʻekiʻe a me ka brittleness, paʻakikī pinepine nā ʻano hana hana kuʻuna e hoʻokō i nā koi a hiki ke alakaʻi maʻalahi i nā hemahema e like me nā māwae a me ka deformation o ka huahana.ʻO ka lua, hoʻohana ʻia ka carbide cemented i nā kula kiʻekiʻe, no laila kiʻekiʻe loa nā koi no ka pololei machining.I ka wā o ke kaʻina hana, pono e noʻonoʻo ʻia nā mea he nui, e like me ka ʻoki ʻana i nā mea hana, nā mea paʻa, nā ʻāpana kaʻina hana, etc., e hōʻoia i ka pololei o ka huahana.ʻO ka mea hope loa, ʻoi aku ka kiʻekiʻe o nā koi o ka ʻili o ka carbide cemented.Ma muli o kona brittleness ʻoi aku ka maʻalahi o ka ʻili, no laila pono e hoʻohana ʻia nā ʻano hana a me nā mea hana kūikawā (e like me ka ultra-precision grinders, electrolytic polishers, etc.) e hōʻoia i ka maikaʻi o ka ʻili.
I ka pōkole, ua hoʻohana nui ʻia ka carbide cemented i ka mīkini CNC, e pāʻani ana i kahi kuleana nui i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka hana a me ka maikaʻi o ka huahana i nā mīkini, uila, kemika, aerospace a me nā ʻoihana ʻē aʻe. .ʻO kahi ʻōnaehana mana koʻikoʻi koʻikoʻi i ka wā o ke kaʻina hana e hōʻoia i kēlā me kēia ʻāpana e hoʻokō i nā koi o nā mea kūʻai aku a me nā kūlana.
