Nā hiʻohiʻona hana o nā mea hana ʻoki carbide

① ʻO ka paʻakikī kiʻekiʻe: hana ʻia ka mea hana carbide cemented me ka paʻakikī kiʻekiʻe a me ka helu heheʻe (i kapa ʻia ʻo ka pae paʻakikī) a me ka mea hoʻopaʻa metala (i kapa ʻia ʻo ka hoʻopaʻa ʻana) ma ke ʻano metallurgy pauka, hiki i kona paʻakikī i 89 ~ 93HRA, ʻoi aku ka kiʻekiʻe ma mua o ke kila kiʻekiʻe. ma 5400C, hiki i ka paʻakikī ke hiki i 82 ~ 87HRA, a me ka paʻakikī kila kiʻekiʻe ma ka lumi wela (83 ~ 86HRA) like.ʻOkoʻa ka waiwai paʻakikī o ka carbide i hoʻopaʻa ʻia me ke ʻano, ka nui, ka nui o ka ʻāpana a me ka maʻiʻo o ka pae hoʻopaʻa metala, a e emi maʻamau me ka piʻi ʻana o ka maʻiʻo o ka pae metala paʻa.ʻOi aku ka ʻoi aku o ka paʻakikī o ka alloy YT ma mua o ko YG alloy inā like ka ʻike o ka pae hoʻopaʻa, a ʻoi aku ka paʻakikī o ka paʻa me TaC(NbC).

② ʻO ka ikaika kulou a me ka paʻakikī: ʻo ka ikaika kulou o ka carbide cemented maʻamau i ka laulā o 900 ~ 1500MPa.ʻO ke kiʻekiʻe o ka maʻiʻo o ka pae hoʻopaʻa metala, ʻoi aku ka kiʻekiʻe o ka ikaika kulou.Ke like ka maʻiʻo o ka adhesive, ʻoi aku ka ikaika o ka YG (WC-Co) alloy ma mua o ka YT (WC-TiC-Co), a emi ka ikaika me ka piʻi ʻana o ka ʻike TiC.ʻO Tungsten carbide kahi mea palupalu, a ʻo kona ʻano paʻakikī i ka lumi wela he 1/30 a 1/8 wale nō o ke kila kiʻekiʻe.

(3) Hoʻohana maʻamau ka mea hana carbide

Hoʻohana nui ʻia nā alloy YG no ka hoʻoili ʻana i ka hao, nā metala non-ferrous a me nā mea non-metallic.ʻO ka carbide palaoa maikaʻi (e like me YG3X, YG6X) i ka nui like o ka cobalt ma mua o ka paʻakikī o ka palaoa a ʻoi aku ka maikaʻi o ka pale ʻana, kūpono no ka hana ʻana i kekahi hao paʻakikī kūikawā, austenitic stainless steel, heat-resistant alloy, titanium alloy, keleawe paʻakikī. a me nā mea hoʻoheheʻe hiki ke ʻaʻahu.

ʻO nā pōmaikaʻi koʻikoʻi o ka YT class cemented carbide he paʻakikī kiʻekiʻe, ke kūpaʻa wela maikaʻi, ka paʻakikī kiʻekiʻe a me ka ikaika compressive ma mua o ka papa YG, maikaʻi ke kūpaʻa oxidation.No laila, i ka wā e koi ʻia ai ka pahi e ʻoi aku ka kiʻekiʻe o ke kūpaʻa wela a me ke kūpaʻa ʻana, pono ke koho ʻia ka brand me ka TiC kiʻekiʻe.Kūpono ka YT alloy no ka hana ʻana i nā mea plastik e like me ke kila, akā ʻaʻole kūpono no ka hana ʻana i ka titanium alloy, silicon alumini alloy.

Loaʻa nā ʻāpana YW i nā ʻāpana YG a me YT, a loaʻa nā waiwai piha maikaʻi.Hiki ke hoʻohana ʻia no ka hana ʻana i ke kila, ka hao a me nā metala non-ferrous.ʻO ia mau mea hoʻohui, inā hoʻonui pono ʻia ka cobalt content, hiki ke ikaika loa a hiki ke hoʻohana ʻia no ka mīkini paʻakikī a me ka ʻoki ʻana o nā mea paʻakikī like ʻole.
