ʻO kahi mea hoʻohui i hanaʻia o kahi pūpū paʻakikī o kahi mea hoʻomehana a me nā mea hao binder ma o kahi kaʻina metallurgy. Ua loaʻa i kahi o ka cerbide i loaʻa i nāʻano maikaʻi loa e like me ka paʻakikī kiʻekiʻe, e nānā i ke kū'ēʻana a me ka paleʻana i keʻano kiʻekiʻe o 500 ° C. Hoʻohana nuiʻia ka Carbie i nā meaʻonaʻono, e like me nā hoʻololi kila, nā kīlele kīlepa, hāmeʻa a me nā papa kūʻai. ʻO ka wikiwiki o kaʻokiʻana o nā mea hana o nā limahana kaʻa hou i kēia manawa he mau haneli mau manawa o ke kaʻa kaʻa kaʻa.
Ke noiʻana o ka cermend carbed
(1) Nā mea hana pono
ʻO ka Carbide ka hapa nui o nā mea hana pono, hiki ke lilo ke hoʻololi i nā mea hoʻonaninani, nā mribst, nā pahu kīwī, nā mribt He kūpono ka carbide-titanium-cobade carbide no ka hoʻohanaʻana i ka loli lōʻihi o nā metala ferous e like me ke kila. Chip machining. Ma waena o nā mea hou like, ua kūpono nā mea me kaʻikepili cobat i kūpono no ka mana kīnāʻole, a me nā mea me ka maʻalahi o ka cellat me ka hoʻopauʻana. ʻO ka maʻamau maʻamau-kumu i hanaʻia i nā carbides i ke ola ma mua o ke olaʻana ma mua o nā crament'ē aʻe no nā mea paʻakikī e like me nā mea kilokilo paʻakikī.
(2) mold kumu
Ua hoʻohana nuiʻia ka cerbide i hoʻohanaʻia no ka hana anuanu e like me keʻano o ke kiʻiʻana i nā make, nā make maloʻo, a me nā makeʻana o ke anuanu.
Pono ke kīʻana i ke poʻo poʻo i ke poʻo poʻo e pono ai e loaʻa i ka hopena maikaʻi maikaʻi, ka ikaika a me ka ikaika o ka hopena o ka hopena. Hoʻohana pinepineʻia ka coblat a me ke kiʻekiʻe kiʻekiʻe a me nā kiʻekiʻe a me nā kilokilo a me nā birse
Hoʻohālikelike nuiʻia, ua kūlike ka pilina ma waena o ke pale pale a me ka paʻakikī o ka maʻa hakakā, e alakaʻiʻia ka hoʻonuiʻana i nā paleemae lole lole lole lole. No laila, ke kohoʻana i nā helu alloy
Ināʻo ka papa i kohoʻia e pili ana i ka hana mua a me ka hōʻino i ka wā e hoʻohana ai, e kohoʻia ka paʻakikī me ka paʻakikī kiʻekiʻe; Ināʻo ka helu i kohoʻia e hoʻopaʻa mua i ka lole a me ka hōʻino i ka wā e hoʻohana ai,ʻo ka papa me ka paʻakikī kiʻekiʻe e kohoʻia. . ^. Eia nā Helu Helu: YG15c, Yg18C, YG20c,ʻo YL60C,ʻo YTG22C,ʻo YG222C, a hoʻonuiʻia ka mea paʻakikī ma ke kue, he oiaio ka mea e kue ai.
(3) ke anaʻana i nā mea hana a me nā'āpana paʻa
Hoʻohanaʻia ka Carbide no nā mea e komo ai i nā mea i hoʻopaʻaʻia a me nā'āpana o nā mea hana, nā mea hana kūpono a me ke alakaʻi i nā'āpana a me nā alanui'ē aʻe.
ʻO nā mea kanu Binder meals ka maʻamau o ka huiʻana,ʻo Cobalat Cobalat lāuaʻo Nicikel.
Ke hana nei i ka hana i hanaʻia,ʻo ka nui o ka'āpana o ka pauna i kohoʻia ma waena o 1 a me 2 micrin, a kiʻekiʻe loa ka maʻemaʻe. Hoʻopiliʻia nā huahana Raw e like me keʻano hoʻohālikelike o ka mea i kuhikuhiʻia, a me ka waiʻona a iʻole nā mea'ē aʻe i hoʻohuiʻia iā lākou e hoʻopili ponoʻia a pulupulu. E hoʻomoʻi i ka hui. A laila,'ōlelo akuʻo ke kāwiliʻana, i paʻiʻia, a hoʻohikiʻia i kahi mahana kokoke i ka manile meloken. Ma hope o ka holoiʻana, ua hoʻokaʻawaleʻia nā pana paʻakikī i ka pahu i hoʻopaʻaʻia i ka mea hao a me nā mea e hoʻopiliʻia ai kekahi i kahi paʻa. ʻO ka paʻakikī o ka laweʻana i ka curnaded carbide i hilinaʻi i ka nui o nā mea i hoʻopaʻaʻia a me ka nui grain,ʻo ia hoʻi,ʻoi aku kaʻoi aku kaʻoi aku ka paʻakikī. Ua hoʻoholoʻia ka paʻakikī o ka ceneride carbide e ka mea hao binder. ʻO ka mākaʻalani kikokiloʻo Binderye mekala,ʻo ka kiʻekiʻe loa.
I ka makahiki 1923, schlerter o Germany i hoʻohuiʻia 10% a 20% corbat i ka paleʻana i ka cerbided i kahi kaʻaahi a me ka copert. ʻO ka paʻakikī ka lua wale nō e daimana. Ka mea i hana muaʻia i hanaʻia. Keʻoki nei ka mea kila me kahi mea hana i hanaʻia i kēia alloy, e kū koke kaʻaoʻaoʻoki i loko, aʻo ke kihiʻoki e hukiʻia. I ka makahiki 1929, Schwarkov i ka United States i hoʻohuiʻia i kahi nui o ka carbiden carbide a me ka hana o ka carbie carpide. ʻO kēia kahi hoʻokō'ē aʻe i ka mōʻaukala o ke kūkuluʻana i keʻano o ka cermend carbide.
Ua loaʻa i kahi o ka cerbide i loaʻa i nāʻano maikaʻi loa e like me ka paʻakikī kiʻekiʻe, e nānā i ke kū'ēʻana a me ka paleʻana i keʻano kiʻekiʻe o 500 ° C. Hoʻohana nuiʻia ka Carbie i nā meaʻonaʻono, e like me nā hoʻololi kila, nā kīlele kīlepa, hāmeʻa a me nā papa kūʻai. ʻO ka wikiwiki o kaʻokiʻana o nā mea hana o nā limahana kaʻa hou i kēia manawa he mau haneli mau manawa o ke kaʻa kaʻa kaʻa.
Hiki ke hoʻohanaʻia nā kāwele i hana i nā mea hana hoʻoikaika, nā mea hana hana, nā mea hana paʻa, nā mea hana kīwaha
Ma hope, ua puka maiʻo ia i ka pale I ka makahiki 1969, ua hana maikaʻiʻo Sweden i kahi mea hoʻokele Catanim Carbide i hanaʻia. ʻO ke kumu o ka mea hanaʻo TUNGSTEN-CANBERAUM-CERBALT CARBIDE a iʻole TungSTEN-CUBERSTEN-COPELTT CRABIDE. ʻO ka mānoanoa o ka carbide carbide carbide carbide ma luna o kaʻili, akā ua hoʻonuiʻia keʻano o nā hana hana likeʻole, a ua hoʻonuiʻia ka wikiwiki I nā makahiki 1970, heʻehā o nā mea hana i hoʻopaʻaʻia no kaʻokiʻana i nā mea hana paʻakikī-i-mīkini.
Pehea ka hanaʻana o ka carbied carbied?
ʻO ka cemented carbide he mea kilokilo i hanaʻia e nā metallitury a me nā binder metals i hoʻokahi a iʻole nā metala hou.
Mnā'āina āpau
Uaʻoi aku ma mua o 50 mau'āina ma ka honua e hana i ka carmented carbide, me ka huina o 27,000-28,000AT-. ʻO nā mea hana nui iʻAmelika,ʻo Russia, sweden, cameren,ʻo Kelemania,ʻo ka hui pūʻana,ʻoʻAmelika Hui PūʻIa , ua huhū nui ka hoʻokūkū mākeke. Ua hoʻomakaʻo China i ka hana Carbied Carbily e lawe i keʻano i ka hopena o 1950s. Mai nā makahiki 1960 a hiki i ka makahiki 1970 I nā makahiki he 190s, ka hana holoʻokoʻa o ka hana o China i ka ceren i hiki i ka curnad cened i hōʻea i ka makahiki 6000, a me nā hui holoʻokoʻa wale nō ma ka honua.
