E like me ke koho ʻana i ke kila, ʻo ke koho ʻana i ka pae maikaʻi loa o ka tungsten carbide (WC) he kaʻina hana paʻakikī e pili ana i nā koho i hoʻohālikelike ʻia ma waena o ka pale ʻaʻahu a me ka paʻakikī / kūʻē haʻalulu. Hana ʻia ka tungsten carbide i hoʻopaʻa ʻia e ka sintering (ma ke kiʻekiʻe kiʻekiʻe) ka hui pū ʻana o ka pauka tungsten carbide me ka pauka cobalt (Co), he metala ductile e lawelawe ana ma ke ʻano he "binder" no nā ʻāpana tungsten carbide paʻakikī loa. ʻO ka wela o ke kaʻina hana sintering ʻaʻole ia e hoʻopili i ka hopena o nā constituents 2, akā naʻe ke kumu o ka cobalt e hiki i kahi kūlana kokoke-wai a lilo e like me kahi matrix glue encapsulating no nā ʻāpana WC (ʻaʻole i hoʻopilikia ʻia e ka wela). ʻElua mau ʻāpana, ʻo ia ka ratio o Cobalt i WC a me ka nui o ka WC particle, e hoʻomalu nui i nā waiwai waiwai nui o ka ʻāpana "cemented tungsten carbide" i hopena.
.
ʻO ka wehewehe ʻana i kahi ʻāpana WC nui a me ka pākēneka kiʻekiʻe o Cobalt e hāʻawi i kahi ʻāpana kūʻokoʻa (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 ka WC e uhi ʻia me Cobalt) a me ka hoʻohana ʻole ʻana o Cobalt, ʻoi aku ka paʻakikī a ʻoi aku ka paʻakikī o ka hopena. No ka loaʻa ʻana o ka hana maikaʻi loa mai ka carbide ma ke ʻano he mea maka, he mea nui ia e pale i ka hāʻule mua ʻana o ka ʻaoʻao i hoʻokumu ʻia e ka ʻokiʻoki a i ʻole ka haki ʻana, ʻoiai e hōʻoiaʻiʻo ana i ke kūpaʻa maikaʻi loa.
Ma ke ʻano he hana kūpono, ʻo ka hana ʻana i nā ʻoki ʻoki ʻoki ʻoki loa a me ka ʻokiʻoki ʻokiʻoki e kuhikuhi i ka hoʻohana ʻana i kahi carbide grained maikaʻi i nā noi maka (i mea e pale aku ai i nā nicks nui a me nā ʻaoʻao ʻala). Hāʻawi ʻia i ka hoʻohana ʻana i ka carbide nona ka nui o ka palaoa awelika o 1 micron a i ʻole ka liʻiliʻi, ka hana carbide blade; no laila, lilo nui i ka % o Cobalt a me ka geometry lihi i kuhikuhi ʻia. Hoʻohana maikaʻi ʻia nā noi ʻoki e pili ana i nā haʻalulu haʻahaʻa haʻahaʻa a kiʻekiʻe ma ke kuhikuhi ʻana i ka 12-15 pākēneka Cobalt a me ka geometry lihi me kahi kihi kihi i hoʻopili ʻia ma kahi o 40º. ʻO nā noi e pili ana i nā ukana māmā a kau i ka uku no ke ola lōʻihi o ka lau he mau moho maikaʻi no ka carbide i loaʻa ka 6-9 pākēneka kobalt a loaʻa kahi kihi kihi i loko o ka laulā o 30-35º.
ʻO Tungsten Carbide ka mea lōʻihi loa i loaʻa no nā noi slitting. Ua ʻike mākou ua ʻaʻahu a hiki i ka 75X ʻoi aku ka lōʻihi ma mua o nā pale kila maʻamau. Inā makemake ʻoe i kahi pahi lōʻihi, hāʻawi pinepine ʻo Tungsten Carbide iā ʻoe i ke ola ʻaʻahu āu e pono ai e hoʻonui i kāu huahana.
Hoʻohana wale ʻo Passion Tool i ka Tungsten Carbide kiʻekiʻe loa e hōʻoia i ka loaʻa ʻana o kā mākou mea kūʻai aku i ka ʻoi loa a me ka lōʻihi o ka ʻaʻahu ʻana. ʻO kā mākouNā lāʻau Carbidehana ʻia mai nā mea nona ka Sub-Micron Grain Structure a ua hele ma ke kaʻina HIP (Hot Isostatic Press) e hōʻoia i ka lole lōʻihi loa a me nā kihi ʻoi loa. Nānā pū ʻia kēlā me kēia lau ma lalo o ka hoʻonui ʻia no ka mana maikaʻi.
He hana mana ia no ka carbide raw material e hele mai ka pauka a i ka pahi ʻoihana semi-finished product, a mai ka semi-finished product to precision tool ke kaʻina hana o ke akamai. E kohoNA MEA HANA MAKEMAKE®, koho i kahi hale hana WC kiʻekiʻe, e lanakila iā ʻoe i nā mea kūʻai aku kiʻekiʻe.
