ʻO ka ʻokoʻa ma waena o nā ʻōwili tungsten carbide a me nā ʻōwili seramika

Mai ka hiʻohiʻona o ka haku mele ʻana, ua hoʻomākaukau nui ʻia nā ʻōwili carbide cemented e ke kaʻina hana pauka e ka pauka metallurgy kaʻina me ka hoʻohana ʻana i nā pūhui metala refractory (e like me ka tungsten carbide WC, titanium carbide TiC, etc.) e like me ka matrix, a me nā metala hoʻololi (e like me cobalt Co, nickel Ni, etc.) ma ke ʻano he mea hoʻopili. ʻO kēia hui kūikawā o nā mea e hāʻawi ai i ka tungsten carbide rolls i kahi kiʻekiʻe o ka paʻakikī, ke kūpaʻa a me ka pale ʻana i ka luhi wela, e hiki ai iā lākou ke pale i ka ʻaʻahu ikaika a me ka waimaka o nā kaʻina hana kiʻekiʻe, kiʻekiʻe a me ka wikiwiki. Hoʻokumuʻia ka'ōwili ceramic ma luna o ka mea seramika a hanaʻia e kahi hana kūikawā. ʻO ka mea keramika ponoʻī he kiʻekiʻe loa ka paʻakikī a me ke kūpaʻa corrosion maikaʻi loa, kahi e hana maikaʻi ai ka ʻōwili ceramic i ke kaʻina o ka ʻōwili, ʻoi aku ka nui o nā koi kiʻekiʻe no ka hoʻopau ʻana i ka ʻili a me ke kūpaʻa corrosion o ka ʻōwili.

Ma nā ʻōlelo o nā hiʻohiʻona hana, ʻike ʻia nā ʻōwili tungsten carbide no ko lākou pale ʻana a me ke kūpaʻa luhi wela. Loaʻa iā ia ka paʻakikī kiʻekiʻe a me ke kūpaʻa wela maikaʻi, a hiki ke holo paʻa no ka manawa lōʻihi i kahi kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa holo kaiapuni, kahi e hoʻomaikaʻi nui ai i ka hana pono o ka wili wili. Eia kekahi, ʻo ka tungsten carbide rolls ka maikaʻi o ka conductivity thermal, hiki ke hoʻopau koke i ka wela i hana ʻia i ka wā o ka ʻōwili ʻana, e hoʻemi i ka wela o ka ʻili o nā ʻōwili, a hoʻemi i ka pōʻino o ke kaumaha wela i nā ʻōwili. ʻO nā ʻōwili seramika, ma ka ʻaoʻao ʻē aʻe, ua ʻike ʻia e ko lākou paʻakikī kiʻekiʻe, ke kūpaʻa corrosion a me ke kūpaʻa wela kiʻekiʻe. ʻO nā mea kūikawā o nā mea seramika e hana i nā'ōwili seramikaʻaʻole i maʻalahi e hoʻopauʻia e nā kemika i ka wā o ka'ōwili, a hiki ke mālama i ka hopena a me ka pololei o ka'ōwili'ōwili no ka manawa lōʻihi. I ka manawa like, hiki i nā ʻōwili ceramic ke mālama i ka hana paʻa i nā kaiapuni kiʻekiʻe, ʻaʻole e hoʻoheheʻe a palupalu paha ma muli o ka piʻi ʻana o ka mahana.

Ma ke ʻano o ka noi, hoʻohana nui ʻia nā ʻōwili carbide cemented i ka hana ʻōwili ʻana o ke kila, nā metala non-ferrous, nā mea hao a me nā ʻoihana ʻē aʻe no ko lākou mau waiwai maikaʻi. ʻOi aku ma nā wahi ʻōwili ikaika kiʻekiʻe e like me ke kiʻekiʻe-wikiwiki uea koʻokoʻo wili wili a me ka hoʻopau ʻana i nā wili wili, cemented carbide rolls play a irreplaceable role. Hoʻohana nui ʻia nā ʻōwili seramika i nā laina hana ʻōwili wela a me ke anuanu i ka ʻoihana kila, ka hana seramika, ka hana aniani a me ka ʻoihana uila ma muli o ko lākou paʻakikī kiʻekiʻe, ke kūpaʻa corrosion a me ke kūpaʻa wela kiʻekiʻe.
