I ka ʻokiʻoki metala, ua kapa mau ʻia ka mea ʻokiʻoki i nā niho o ka hana ʻoihana, a ʻo ka hana ʻoki ʻana o ka mea hana ʻoki ʻoki kekahi o nā kumu nui e hoʻoholo ai i kona pono hana, ke kumukūʻai hana a me ka maikaʻi o ka hana. No laila, he mea koʻikoʻi ke koho pololei ʻana i nā mea hana ʻoki.
ʻO ka mea paahana e pili ana i ka mea o ka ʻāpana ʻoki o ka mea hana.
ʻO ka mea kikoʻī, ʻo ke koho kūpono o nā mea hana e pili ana i kēia mau ʻano:
ʻO ka huahana mīkini, ka lōʻihi o ka mea hana, ka hoʻohana ʻana i nā mea hana a me nā kumukūʻai mīkini, ka pololei o ka mīkini a me ka maikaʻi o ka ʻili.
Ke manaʻoʻiʻo ʻia ʻo nā mea paahana e pili ana i ke kila kila kila, ke kila kila kila, ke kila kiʻekiʻe, ka paʻa paʻa, nā ceramics, cermets, daimana, cubic boron nitride, etc.
ʻO Cermet kahi mea i hui pū ʻia
Cermet
ʻO ka huaʻōlelo Pelekania ʻo cermet a i ʻole ka ceramet ka mea i haku ʻia me ka ceramic (ceramic) a me ka metala (metala). ʻO Cermet kahi ʻano mea hoʻohuihui, a ʻokoʻa iki kona wehewehe ʻana i nā manawa like ʻole.
(1) Ua wehewehe ʻia kekahi ma ke ʻano he mea i haku ʻia me nā seramika a me nā metala, a i ʻole he mea i hui pū ʻia me nā seramika a me nā metala i hana ʻia e ka pauda metallurgy.
ʻO ke Kōmike Hoʻonaʻauao ʻAmelika ʻAmelika Hui Pū ʻIa e wehewehe iā ia e like me: he mea heterogeneous composite i haku ʻia me ka metala a i ʻole nā mea hoʻoheheʻe a hoʻokahi a ʻoi aku ka nui o nā ʻāpana seramika, ʻo ia ka mea ma kahi o 15% a hiki i 85% hapa hapa leo, a ma ka mahana hoʻomākaukau, ʻO ka solubility ma waena o ka ʻoi aku ka liʻiliʻi o nā pae metala a me ka ceramic.
ʻO nā mea i hana ʻia me ka metala a me ka ceramic maka he mau mea maikaʻi o nā metala a me nā seramika, e like me ka paʻakikī a me ke kūlou ʻana o ka mua, a me ke kūpaʻa wela kiʻekiʻe, ka ikaika kiʻekiʻe a me ke kūpaʻa oxidation o ka hope.
(2) ʻO Cermet kahi carbide i hoʻopaʻa ʻia me ka titanium-based particle paʻakikī e like me ke kino nui. ʻO ka inoa Pelekane o cermet, cermet, he hui pū ʻia o nā huaʻōlelo ʻelua ceramic (ceramic) a me metala (metala). Hoʻonui ʻo Ti(C,N) i ke kūpaʻa ʻaʻahu o ka papa, ʻo ka lua o ka paʻakikī e hoʻonui i ke kūʻē i ka deformation plastic, a ʻo ka ʻike cobalt e hoʻomalu i ka paʻakikī. Hoʻonui nā Cermets i ka pale ʻana a hoʻemi i ka manaʻo e pili i ka mea hana i hoʻohālikelike ʻia me ka carbide sintered.
Ma ka ʻaoʻao ʻē aʻe, loaʻa iā ia ka ikaika compressive haʻahaʻa a me ke kūpaʻa haʻahaʻa haʻahaʻa haʻahaʻa. He ʻokoʻa nā Cermets mai nā alloys paʻakikī no ka mea ʻo kā lākou mau mea paʻakikī no ka ʻōnaehana WC. Hoʻokumu nui ʻia nā Cermets i nā carbide a me nā nitrides i hoʻokumu ʻia ʻo Ti, a ua kapa ʻia hoʻi ʻo Ti-based cemented carbide.
ʻO nā cermets maʻamau pū kekahi me nā mea hoʻohuihui refractory, nā mea paʻa paʻa, a me nā mea hana daimana i hoʻopaʻa ʻia. ʻO ka māhele keramika i loko o nā cermets he oxide a refractory pūhui me ka helu heheʻe kiʻekiʻe a me ka paʻakikī kiʻekiʻe, a ʻo ka pae metala ka nui o nā mea hoʻololi a me kā lākou mau ala.
ʻO Cermet kahi ʻano mea hoʻohuihui, a ʻokoʻa iki kona wehewehe ʻana i nā manawa like ʻole.
ʻO Cermets nā mea hana ʻoki metala
mea nui
Ke hoʻomaikaʻi ʻia nei nā Cermets
Ke manaʻoʻiʻo ʻia ʻo nā mea paahana e pili ana i ke kila kila kila, ke kila kila kila, ke kila kiʻekiʻe, ka carbide cemented, cermet, ceramics, daimana, cubic boron nitride, etc.
I ka makahiki 1950, ua hoʻohana mua ʻia nā cermets TiC-Mo-Ni ma ke ʻano he mea paahana no ka ʻoki kiʻekiʻe o ke kila.
I ka wā mua, ua hana ʻia nā cermets mai TiC a me nickel. ʻOiai he kiʻekiʻe kona ikaika a me ka paʻakikī kiʻekiʻe e hoʻohālikelike ʻia me ka carbide cemented, ʻano ʻilihune kona paʻakikī.
I nā makahiki 1970, ua hoʻomohala ʻia nā cermets-based TiC-TiN, nā cermets nickel-free.
ʻO kēia cermet hou, me nā ʻāpana titanium carbonitride Ti (C, N) ma ke ʻano he mea nui, kahi liʻiliʻi o ka lua paʻakikī (Ti, Nb, W) (C, N) a me ka tungsten-cobalt-rich binder, hoʻomaikaʻi i ka metala. Ua hoʻomaikaʻi ka paʻakikī o nā seramika i kā lākou hana ʻokiʻoki, a mai ia manawa ua hoʻohana nui ʻia nā cermets i ka hoʻomohala ʻana i nā mea hana.
Me kona kūpaʻa wela maikaʻi loa, ke kūpaʻa a me ke kūpaʻa kemika, ua hōʻike nā mea hana cermet i nā mea maikaʻi ʻole ma ke kahua o ka ʻoki kiʻekiʻe a me ka ʻoki ʻana i nā mea paʻakikī i ka mīkini.
Hoʻomaikaʻi ʻo Cermet + PVD coating i ka pale ʻana i ka lole
e hiki mai ana
Ke piʻi nei ka hoʻohana ʻana i nā pahi cermet ma nā ʻano like ʻole i kēlā me kēia lā, a ʻaʻohe kānalua e hoʻomohala hou ʻia ka ʻoihana cermet.
Hiki ke uhi ʻia nā Cermets me ka PVD no ka hoʻomaikaʻi ʻana i ke kūpaʻa lole.
