ʻO ka paʻakikī o ka tungsten carbide

(1) ʻO ka paʻakikī kiʻekiʻe, ke kūpaʻa a me ka ʻulaʻula
ʻO ka paʻakikī carbide i hoʻopaʻa ʻia i ka lumi wela hiki ke hiki i 86 ~ 93HRA, e like me 69 ~ 81HRC.ma 900 ~ 1000 ℃ hiki ke mālama i ka paʻakikī kiʻekiʻe, a me ke kūpaʻa maikaʻi loa.Ke hoʻohālikelike ʻia me ke kila mea hana kiʻekiʻe, hiki i ka wikiwiki ʻoki ke 4 a 7 mau manawa kiʻekiʻe, ola 5 a 80 mau manawa lōʻihi, hiki ke ʻoki i nā mea paʻakikī me ka paʻakikī a hiki i 50HRC.
(2) Ka ikaika, modulus kiʻekiʻe o ka elasticity
ʻO ka ikaika compressive o ka cemented carbide a hiki i 6000MPa, elastic modulus o (4 ~ 7) × 105MPa, ʻoi aku ka kiʻekiʻe ma mua o ke kila kiʻekiʻe.Eia naʻe, ʻoi aku ka haʻahaʻa o kona ikaika flexural, maʻamau 1000 a 3000 MPa.

(3) ʻO ke kūpaʻa ʻana o ka corrosion, maikaʻi ke kūpaʻa oxidation
ʻO ke kūpaʻa maikaʻi i ka corrosion o ka lewa, ka waikawa, ka alkali, a me nā mea ʻē aʻe, ʻaʻole maʻalahi i ka oxidation.
(4) Ka helu liʻiliʻi o ka hoʻonui laina
Paʻa ke ʻano a me ka nui i ka wā e hana ai.
(5) ʻAʻole hana hou ʻia nā huahana i kūkulu ʻia

Ma muli o ke kiʻekiʻe o ka paʻakikī a me ka brittleness o ka carbide cemented, ʻaʻole ʻoki hou ʻia a ʻoki ʻia paha ma hope o ka hoʻokumu ʻana o ka metallurgy pauka a me ka sintering, a inā pono e hana hou, hiki ke hoʻohana ʻia nā mīkini uila e like me EDM, ʻoki uila, electrolytic grinding a i ʻole huila wili kūikawā. .ʻO ka maʻamau, hoʻopaʻa ʻia kekahi kikoʻī o nā huahana i hana ʻia me ka carbide cemented, hoʻopaʻa ʻia a hoʻopaʻa ʻia paha ma ke kino o ka mea hana a i ʻole ka poʻi no ka hoʻohana ʻana.
