ʻIke o nā pahi tungsten carbide

Nā pahi ʻokiʻoki Tungsten Carbide
Me ke koho ʻana i ka papa kūpono loa, hiki ke hoʻoʻoi ʻia nā pahi tungsten carbide submicron nui i kahi lihi razor me ka ʻole o ka brittleness kūlohelohe e pili pinepine ʻia me ka carbide maʻamau. ʻOiai ʻaʻole i like ka pale ʻana i ka haʻalulu e like me ke kila, he kūpaʻa loa ka carbide i ka ʻaʻahu ʻana, me ka paʻakikī e like me Rc 75-80. Hiki ke manaʻo ʻia ke ola o ka pahi o ka liʻiliʻi he 50X mau kila pahi maʻamau inā pale ʻia ka chipping a me ka haki ʻana.

E like me ke koho ʻana i ke kila, ʻo ke koho ʻana i ka papa kūpono o ka tungsten carbide (WC) he hana paʻakikī e pili ana i nā koho i hoʻopilikia ʻia ma waena o ke kūpaʻa ʻana i ka ʻaʻahu a me ke kūpaʻa/kūʻē haʻalulu. Hana ʻia ka tungsten carbide i hoʻopaʻa ʻia ma ka sintering (ma ke ana wela kiʻekiʻe) kahi hui pū ʻana o ka pauka tungsten carbide me ka cobalt pauka (Co), kahi metala ductile e lawelawe ana ma ke ʻano he "mea hoʻopaʻa" no nā ʻāpana tungsten carbide paʻakikī loa. ʻAʻole pili ka wela o ke kaʻina hana sintering i ka hopena o nā ʻāpana 2, akā naʻe ke kumu o ka cobalt e hiki i kahi mokuʻāina kokoke i ka wai a lilo e like me kahi matrix glue encapsulating no nā ʻāpana WC (ʻaʻole i hoʻopilikia ʻia e ka wela). ʻElua mau palena, ʻo ia hoʻi ka lakio o Cobalt i WC a me ka nui o ka ʻāpana WC, e kāohi nui i nā waiwai o ka nui o ka ʻāpana "tungsten carbide i hoʻopaʻa ʻia".
ʻO ka hoʻākāka ʻana i ka nui o nā ʻāpana WC nui a me ka pakeneka kiʻekiʻe o Cobalt e hua mai i kahi ʻāpana kūpaʻa loa i ka haʻalulu (a me ka ikaika hopena kiʻekiʻe). ʻO ka ʻoi aku ka maikaʻi o ka nui o ka palaoa WC (no laila, ʻoi aku ka nui o ka ʻili o WC e pono e uhi ʻia me Cobalt) a ʻo ka liʻiliʻi o ka Cobalt i hoʻohana ʻia, ʻoi aku ka paʻakikī a me ka pale ʻana i ke komo ʻana o ka ʻāpana hopena. No ka loaʻa ʻana o ka hana maikaʻi loa mai ka carbide ma ke ʻano he mea pahi, he mea nui e pale i nā hemahema lihi mua i hoʻokumu ʻia e ka chipping a i ʻole ka haki ʻana, ʻoiai e hōʻoiaʻiʻo ana i ke kūpaʻa komo maikaʻi loa.

Ma ke ʻano he mea pono, ʻo ka hana ʻana o nā ʻoki ʻoi loa a me ke kihi ʻoi loa e koi ana e hoʻohana ʻia kahi carbide maikaʻi i nā noi pahi (i mea e pale ai i nā nicks nui a me nā ʻaoʻao ʻino). Hāʻawi ʻia i ka hoʻohana ʻana o ka carbide nona ka nui o ka palaoa awelika o 1 micron a i ʻole ka liʻiliʻi, ka hana o ka pahi carbide; no laila, lilo ia i mea nui i ka % o Cobalt a me ke ʻano o ka ʻaoʻao i kuhikuhi ʻia. ʻOi aku ka maikaʻi o ka hana ʻana i nā noi ʻoki e pili ana i nā ukana haʻalulu waena a kiʻekiʻe ma ka wehewehe ʻana i ka 12-15 pakeneka Cobalt a me ke ʻano o ka ʻaoʻao me kahi kihi ʻaoʻao i hoʻokomo ʻia ma kahi o 40º. ʻO nā noi e pili ana i nā ukana māmā a kau i kahi premium ma ke ola lōʻihi o ka pahi he mau moho maikaʻi no ka carbide nona ka 6-9 pakeneka cobalt a he kihi ʻaoʻao i hoʻokomo ʻia ma ka laulā o 30-35º.
Ua mākaukau ʻo HUAXIN CARBIDE e kōkua iā ʻoe i ka hoʻokō ʻana i ke kaulike kūpono o nā waiwai e hiki ai iā ʻoe ke loaʻa ka hana kiʻekiʻe loa mai kāu mau pahi carbide.
Hāʻawi ʻo HUAXIN CARBIDE i kahi koho o nā pahi ʻokiʻoki carbide i mālama ʻia
