ʻO nā hiʻohiʻona a me nā hoʻohana ʻana o Titanium Carbide, Silicon Carbide, a me nā mea ʻona Carbide Cemented

I loko o ka "universe material" o ka hana ʻoihana, titanium carbide (TiC), silicon carbide (SiC), a me ka cemented carbide (ma muli o ka tungsten carbide - cobalt, a me nā mea ʻē aʻe) ʻekolu "nā mea hōkū". Me kā lākou mau waiwai kūʻokoʻa, pāʻani lākou i nā kuleana koʻikoʻi ma nā ʻano āpau. I kēia lā, e nānā hohonu mākou i ka ʻokoʻa o nā waiwai ma waena o kēia mau mea ʻekolu a me nā hiʻohiʻona kahi i ʻoi aku ai!

Wehewehe Waiwai:

• Titanium Carbide (TiC): Kokoke kona paakiki i ko daimana, e lilo ia i lala o ka ohana waiwai nui. ʻO kona kiʻekiʻe kiʻekiʻe e hiki ai ke hoʻonohonoho pololei i nā mea hana pono e pono ai ke "kaumaha". Eia nō naʻe, he haʻahaʻa kiʻekiʻe kona a hiki ke ʻoki ʻia ma lalo o ka hopena, no laila ʻoi aku ka maikaʻi no nā hiʻohiʻona kūʻokoʻa, haʻahaʻa - ʻokiʻoki / ʻaʻahu - kūpaʻa. Eia kekahi laʻana, hoʻohana pinepineʻia e like me ka uhiʻana i nā mea hana. ʻOi aku ka paʻakikī o ka uhi ʻana o ka TiC, e like me ke kau ʻana i ka "pale pale" ma ke kila kiʻekiʻe a me nā mea hana carbide cemented. I ka ʻoki ʻana i ke kila kila a me ke kila kila, hiki iā ia ke kū i nā wela kiʻekiʻe a hoʻemi i ka ʻaʻahu, e hoʻonui nui i ke ola mea hana. No ka laʻana, i ka uhi ʻana o ka hoʻopau ʻana i nā mea ʻoki wili, hiki iā ia ke ʻoki wikiwiki a paʻa.
• Kapili Silika (SiC): He "mea hoʻokani kiʻekiʻe ma ke kiʻekiʻe - pale wela"! Hiki iā ia ke mālama i ka hana paʻa ma luna o 1600 ℃. Ma ka moku'āina, he mea kupanaha kona kūpa'a kemika a pa'akikī 'ole ia me nā 'akika a me nā alkalis (koe wale no ka waika hydrofluoric). Eia naʻe, he pilikia maʻamau ka brittleness no nā mea seramika. Eia nō naʻe, ua hoʻomaikaʻi ka paʻakikī o ka carbide silicon crystal (e like me 4H - SiC) a ke hoʻi hou nei i nā semiconductors a me nā mea hana kiʻekiʻe. No ka laʻana, ʻo SiC - nā mea hana seramika he "haumāna kiʻekiʻe" ma waena o nā mea hana seramika. Loaʻa iā lākou ke kūpaʻa kiʻekiʻe - wela a paʻa kemika. I ka wā e ʻokiʻoki ai i nā mea hao kiʻekiʻe - ʻoi aku ka paʻakikī (e like me ka nickel-based alloys) a me nā mea palupalu (e like me ka hao hoʻolei), ʻaʻole lākou e maʻalahi i ka pipili ʻana o ka mea hana a me ka lohi. Eia nō naʻe, ma muli o ka brittleness, ʻoi aku ka maikaʻi o ka hoʻopau ʻana me ka ʻoki ʻoki liʻiliʻi a me ka pololei kiʻekiʻe.
• Carbide Sima (WC – Co): He mea hoʻokani pila ma luna o ke kahua ʻoki! Mai nā mea hana lathe a hiki i nā mea ʻoki wili CNC, mai ka wili kila a hiki i ka pōhaku wili, hiki ke loaʻa ma nā wahi āpau. ʻO ka carbide Cemented me ka maʻiʻo Co haʻahaʻa (e like me YG3X) kūpono no ka hoʻopau ʻana, ʻoiai ʻo ka mea me ka maʻiʻo Co kiʻekiʻe (e like me YG8) maikaʻi ke kūpaʻa hopena a hiki ke mālama i ka mīkini paʻakikī me ka maʻalahi. ʻO nā ʻāpana paʻakikī o ka WC ke kuleana no ka "hoʻopaʻa ʻana" i ka ʻaʻahu, a hana ka Co binder e like me "glue" e hoʻopaʻa pū i nā ʻāpana WC, e mālama i ka paʻakikī a me ka paʻakikī. ʻOiai ʻaʻole maikaʻi kona kūpaʻa kiʻekiʻe - wela e like me nā mea mua ʻelua, ʻo kāna hana kaulike holoʻokoʻa e kūpono ia no nā ʻano hiʻohiʻona nui mai ka ʻoki ʻana a hiki i nā ʻāpana pale.

II. Nā kahua noi i ka holo piha

1. Kahua Mea Hana ʻoki

• Titanium Carbide (TiC): Hoʻohana pinepine ʻia e like me ka uhi ʻana i nā mea hana! ʻO ka uhi ʻoi loa - paʻakikī a paʻa - kūpaʻa ʻo TiC e kau i ka "pale pale" ma luna o ke kila kiʻekiʻe a me nā mea hana carbide cemented. I ka ʻoki ʻana i ke kila kila a me ke kila kila, hiki iā ia ke kū i nā wela kiʻekiʻe a hoʻemi i ka ʻaʻahu, e hoʻonui nui i ke ola mea hana. No ka laʻana, i ka uhi ʻana o ka hoʻopau ʻana i nā mea ʻoki wili, hiki iā ia ke ʻoki wikiwiki a paʻa.
• Kapili Silika (SiC): He "haumāna kiʻekiʻe" ma waena o nā mea hana seramika! He kiʻekiʻe ke kūpaʻa o ka wela a me ke kūpaʻa kemika i nā mea hana seramika e pili ana i ka SiC. I ka wā e ʻokiʻoki ai i nā mea hao kiʻekiʻe - ʻoi aku ka paʻakikī (e like me ka nickel-based alloys) a me nā mea palupalu (e like me ka hao hoʻolei), ʻaʻole lākou e maʻalahi i ka pipili ʻana o ka mea hana a me ka lohi. Eia nō naʻe, ma muli o ka brittleness, ʻoi aku ka maikaʻi o ka hoʻopau ʻana me ka ʻoki ʻoki liʻiliʻi a me ka pololei kiʻekiʻe.
• Carbide Sima (WC – Co): He mea hoʻokani pila ma luna o ke kahua ʻoki! Mai nā mea hana lathe a hiki i nā mea ʻoki wili CNC, mai ka wili kila a hiki i ka pōhaku wili, hiki ke loaʻa ma nā wahi āpau. ʻO ka carbide Cemented me ka maʻiʻo Co haʻahaʻa (e like me YG3X) kūpono no ka hoʻopau ʻana, ʻoiai ʻo ka mea me ka maʻiʻo Co kiʻekiʻe (e like me YG8) maikaʻi ke kūpaʻa hopena a hiki ke mālama i ka mīkini paʻakikī me ka maʻalahi.

2. Wear - Kū'ē Component Field

• Titanium Carbide (TiC): E hana ma ke ʻano he "poʻokela kūʻokoʻa ʻaʻahu" i loko o nā mole pololei! No ka laʻana, i loko o ka pauka metallurgy molds, i ka wā e kaomi ana i ka pauka metala, ʻaʻahu ʻia nā mea hoʻokomo TiC - kūpaʻa a loaʻa ka pololei kiʻekiʻe, e hōʻoia ana i nā ʻāpana i kaomi ʻia i nā ana kūpono a me nā ʻili maikaʻi, a ʻaʻole hiki ke "malfunction" i ka wā hana nui.
• Kapili Silika (SiC): Hāʻawi ʻia me nā "palua pālua" o ke kūpaʻa ʻaʻahu a me ke kūpaʻa kiʻekiʻe - wela! ʻO nā ʻōwili a me nā bearings i nā umu wela kiʻekiʻe i hana ʻia me nā seramika SiC ʻaʻole e palupalu a ʻaʻahu paha ma luna o 1000 ℃. Eia kekahi, hiki i nā nozzles i nā lako sandblasting i hana ʻia me SiC ke kū i ka hopena o nā ʻāpana one, a ʻoi aku ka lōʻihi o ko lākou ola lawelawe ma mua o nā nozzles kila maʻamau.
• Carbide Sima (WC – Co): ʻO kahi "mākaʻikaʻi kūʻokoʻa kūʻokoʻa"! ʻO nā niho carbide i hoʻopaʻa ʻia i loko o kaʻu mau ʻāpana drill hiki ke wāwahi i nā pōhaku me ka ʻole o ka pōʻino; ʻO nā mea ʻoki carbide i hoʻopaʻa ʻia ma nā mea mīkini pale e hiki ke kū i ka lepo a me ke one, a hiki ke "mālama i ko lākou ʻoluʻolu" ʻoiai ma hope o ka hoʻoheheʻe ʻana i mau tausani mika. ʻO nā huila eccentric i loko o nā motika vibration kelepona paʻa e hilinaʻi i ka carbide cemented no ka pale ʻana e hōʻoia i ka haʻalulu paʻa.

3. Mea uila / Semiconductor Field

• Titanium Carbide (TiC): Hōʻike ʻia i loko o kekahi mau mea uila e pono ai ke kiʻekiʻe - ka wela a me ke kūpaʻa ʻaʻahu kiʻekiʻe! No ka laʻana, i loko o nā electrodes o nā paipu electron kiʻekiʻe, he kiʻekiʻe ʻo TiC - ke kūpaʻa wela, ka conductivity uila maikaʻi, a me ke kūpaʻa ʻaʻahu, e hiki ai i ka hana paʻa i nā wahi wela kiʻekiʻe a me ka hōʻoia ʻana i ka lawe ʻana i nā hōʻailona uila.
• Kapili Silika (SiC): He "punahele hou i nā semiconductor"! ʻO nā ʻenehana semiconductor SiC (e like me nā modula mana SiC) he kiʻekiʻe kiʻekiʻe - alapine, kiʻekiʻe - voltage, a me ka hana wela kiʻekiʻe. Ke hoʻohana ʻia i nā kaʻa uila a me nā inverters photovoltaic, hiki iā lākou ke hoʻomaikaʻi nui i ka pono a hoʻemi i ka leo. Eia kekahi, ʻo nā wafers SiC ka "kumu" no ka hana ʻana i nā pahu kiʻekiʻe - pinepine a kiʻekiʻe - wela, a manaʻo nui ʻia i nā kahua kahua 5G a me nā avionics.
• Carbide Sima (WC – Co): He "mea hana pololei" i ka hana uila! Hiki ke loaʻa ke anawaena e like me ka liʻiliʻi e like me ka 0.1mm a hiki ke wili pololei me ka haki ʻole. ʻO nā mea hoʻokomo carbide i hoʻopaʻa ʻia i loko o nā ʻāpana pahu chip he kiʻekiʻe a me ke kūpaʻa ʻana i ka lole, e hōʻoiaʻiʻo ana i ka hoʻopili pololei a paʻa o nā pin chip.

III. Pehea e koho ai?

• No ka paʻakikī loa a me ke kū pololei o ka ʻaʻahu→ E koho i ka titanium carbide (TiC)! No ka laʻana, i loko o nā ʻāpana poni pololei a me nā mea hana paʻakikī paʻakikī, hiki iā ia ke "kūʻai" i ka ʻaʻahu a mālama pono.
• No ka pale wela kiʻekiʻe, kūpaʻa kemika, a i ʻole ka hana ʻana ma nā mea semiconductor / kiʻekiʻe - alapine→ E koho i ka carbide silika (SiC)! He mea nui ia no nā ʻāpana umu wela kiʻekiʻe a me nā ʻāpana mana SiC.
• No ka hana holoʻokoʻa kaulike, e uhi ana i nā mea a pau mai ka ʻoki ʻana a hiki i ka ʻaʻahu - nā noi pale→ E koho i ka carbide sima (WC – Co)! He "mea pāʻani maʻamau" e uhi ana i nā mea hana, drills, a me nā ʻāpana kūʻokoʻa.
