ʻO ke kaʻina hana o ka tungsten copper alloy

Ke kaʻina hana otungsten keleawe huila:
Hoʻohana ʻia ke kaʻina hana ʻenehana no ka hoʻomākaukau ʻana i ka tungsten-copper alloy e ka pauka metallurgy method no ka hui ʻana, ka palena, ka hana ʻana, ka sintering, ka hoʻoheheʻe ʻana, ka infiltration a me ka hana anuanu o nā mea pauka.Hoʻopili ʻia ka pauka Tungsten-copper a i ʻole molybdenum-copper i hui ʻia i loko o ka wai wai ma 1300-1500 ° ma hope o ka hoʻoheheʻe ʻia ʻana.ʻO ka mea i hoʻomākaukau ʻia e kēia ʻano ʻano like ʻole, nui nā wahi i pani ʻia, a ʻoi aku ka haʻahaʻa o ka haʻahaʻa ma mua o 98%.Hiki iā ia ke hoʻomaikaʻi i ka hana sintering a hoʻomaikaʻi i ka maikaʻi o ka tungsten-copper a me ka molybdenum-copper alloys.Eia nō naʻe, ʻo ka hoʻoulu ʻana i ka nickel a me ka sintering e hoʻemi nui i ka conductivity uila a me ka wela o ka mea, a ʻo ka hoʻokomo ʻana i nā haumia i loko o ka hoʻohui ʻana mechanical e hoʻemi i ka conductivity o ka mea;ʻO ke kaʻina hana hoʻihoʻi hou o ka oxide e hoʻomākaukau ai i nā pauka he hana ʻenehana paʻakikī a me ka mana hana haʻahaʻa, he mea paʻakikī ke kaʻina hana.
1. Hana ʻia ke ʻano hana hoʻoheheʻe kiʻekiʻe kiʻekiʻe ma ke ʻano o ka hoʻoheheʻe ʻana.ʻO kāna hana hana ʻo ka hui ʻana i ka pauka nickel, ka pauka tungsten keleawe a i ʻole ka pauka hao me ka nui o ka nui o ka 15 microns, ka pauka tungsten me ka nui o ka 0.52 microns a me ka pauka tungsten o 515 microns, a laila hui pū me 25% 30% mea hoʻopili organik (e like me ka wax keʻokeʻo a i ʻole polymethacrylate) a me ka hoʻomaʻemaʻe ʻana i ka hoʻomaʻemaʻe kiʻekiʻe. wahi tungsten huila.
2. Copper oxide pauda ala Copper oxide pauda (hui a wili no ka hoihoi 'ana i ke keleawe) ma kahi o ka metala keleawe pauda, ​​copper alloy hana i ka matrix mau i loko o ka sintered compact, a me ka tungsten hoʻohana 'ia ma ke ano hooikaika.Hoʻopili ʻia ka ʻāpana pehu kiʻekiʻe e ka ʻāpana lua a puni, a ua hoʻopaʻa ʻia ka pauka i ka haʻahaʻa haʻahaʻa haʻahaʻa.ʻO ke koho ʻana i ka pauka maikaʻi loa hiki ke hoʻomaikaʻi i ka hana sintering a me ka densification, ʻoi aku ia ma mua o 99%.
3. 'O ka tungsten a me ka molybdenum skeleton infiltration method e ho'opa'a mua i ka pauka tungsten a i 'ole ka pauka molybdenum e ho'olike ai, a ho'okomo i loko o ka iwi tungsten a me ka molybdenum me kekahi porosity, a laila komo i ke keleawe.He kūpono kēia ʻano no nā huahana keleawe tungsten a me nā huahana keleawe molybdenum me ka haʻahaʻa haʻahaʻa keleawe.Ke hoʻohālikelike ʻia me ka keleawe tungsten, loaʻa ka molybdenum copper i nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, ka hana maʻalahi, ka hoʻonui laina laina, ka conductivity thermal a me kekahi mau waiwai mechanical a me ka keleawe tungsten.ʻOiai ʻaʻole ʻoi aku ka maikaʻi o ka hana pale wela e like me ke keleawe tungsten, ʻoi aku ka maikaʻi ma mua o kekahi mau mea wela, no laila ʻoi aku ka maikaʻi o ka hoʻohana.No ka mea, ʻoi aku ka maikaʻi o ka wettability o ka molybdenum-copper ma mua o ka tungsten-copper, ʻoi aku ka maikaʻi i ka wā e hoʻomākaukau ai i ka molybdenum-copper me ka haʻahaʻa keleawe keleawe haʻahaʻa, ʻoi aku ka haʻahaʻa o ka mea ma hope o ka infiltration, ka hopena o ka ea o ka mea, conductivity uila, a me ka thermal conductivity ʻaʻole hiki ke hoʻokō i nā koi.Kāohi ʻia kona hoʻohana ʻana.
