ʻO ka tungsten metala, nona ka inoa i loaʻa mai Suedena - tung (kaumaha) a me sten (pōhaku) i hoʻohana nui ʻia i ke ʻano o nā carbide tungsten cemented.ʻO nā carbide cemented a i ʻole nā metala paʻakikī e like me ka mea i kapa pinepine ʻia he papa o nā mea i hana ʻia e ka 'cementing' hua o ka tungsten carbide i loko o kahi matrix binder o ka cobalt metala ma o ke kaʻina i kapa ʻia ʻo ka wai sintering.
I kēia mau lā, ʻokoʻa ka nui o nā huaʻai tungsten carbide mai ka 0.5 microns a i ʻoi aku ma mua o 5 micron me kahi ʻike cobalt hiki ke piʻi i kahi o 30% ma ke kaumaha.Eia kekahi, hiki i ka hoʻohui ʻana i nā carbide ʻē aʻe ke hoʻololi i nā waiwai hope.
ʻO ka hopena he papa o nā mea i hōʻike ʻia e
Ka ikaika kiʻekiʻe
ʻoʻoleʻa
Paʻakiki kiʻekiʻe
Ma ka hoʻololi ʻana i ka nui o ka palaoa o ka tungsten carbide a me ka ʻike cobalt i loko o ka matrix, a me ka hoʻohui ʻana i nā mea ʻē aʻe, hiki i nā ʻenekini ke komo i kahi papa o nā mea nona nā waiwai e hiki ke hoʻohālikelike ʻia i nā ʻano hana ʻenehana.Loaʻa kēia i nā mea hana ʻenehana kiʻekiʻe, nā ʻāpana a me nā mea hana no ka ʻoihana kūkulu hale a me ka ʻaila a me ke kinoea.
ʻO nā huahana Tungsten Carbide ka hopena o kahi kaʻina metala pauka e hoʻohana mua i ka tungsten carbide a me ka pauka metala cobalt.ʻO ka mea maʻamau, ʻo ka hui ʻana o nā hui ʻana mai ka 4% cobalt a i ka 30% cobalt.
ʻO ke kumu nui o ke koho ʻana e hoʻohana i ka tungsten carbide ʻo ia ka hoʻohana ʻana i ka paʻakikī kiʻekiʻe i hōʻike ʻia e kēia mau mea e hoʻopaneʻe ai i ka nui o ka lole o kēlā me kēia mea.ʻO ka mea pōʻino, ʻo ka hoʻopaʻi e pili ana i ka paʻakikī kiʻekiʻe ka nele o ka paʻakikī a i ʻole ka ikaika.ʻO ka mea pōmaikaʻi, ma ke koho ʻana i nā haku mele me nā mea kobalt kiʻekiʻe, hiki ke loaʻa ka ikaika me ka paʻakikī.
E koho i ka maʻiʻo cobalt haʻahaʻa no nā noi kahi e manaʻo ʻole ʻia ai ka ʻāpana e ʻike i ka hopena, loaʻa ka paʻakikī kiʻekiʻe, ke kūpaʻa kiʻekiʻe.
E koho i ka maʻiʻo cobalt kiʻekiʻe inā pili ka haʻalulu a i ʻole ka hopena a loaʻa i ke kūpaʻa lole ʻoi aku ka nui ma mua o ka hapa nui o nā mea ʻē aʻe i hiki ke hāʻawi, i hui pū ʻia me ka hiki ke pale aku i ka pōʻino.
