Kovar huila 4j29

ʻIke ʻia ʻo 4J29 alloy he Kovar alloy. ʻO ka huila he laina hoʻonui laina like me ke aniani paʻakikī borosilicate ma 20 ~ 450 ℃, kahi kiʻekiʻe Curie a me ka paʻa microstructure haʻahaʻa haʻahaʻa. ʻO ke kiʻiʻoniʻoni oxide o ka alloy he paʻa a hiki ke hoʻopili maikaʻi ʻia e ke aniani. ʻAʻole pili pū me ka mercury, kūpono no ka hoʻohana ʻana i ka mea hana me ka hoʻokuʻu mercury. ʻO ia ka mea hoʻokumu hoʻopaʻa hoʻopaʻa nui o ka mea uila uila. Hoʻohana ʻia ia e hana i ka Fe-Ni-Co alloy strip, bar, plate a me ka paipu me ke aniani paʻakikī / sealing pili like, hoʻohana nui ʻia i nā uila uila, nā uila uila a me nā ʻoihana ʻē aʻe.
4J29 Ka nānā ʻana o ka noi a me nā koi kūikawā
ʻO ka huila he Fe-Ni-Co maʻamau i hoʻohana ʻia ma ke ao holoʻokoʻa. Ua hoʻohana ʻia e ka hale hana mokulele no ka manawa lōʻihi a paʻa kāna hana. Hoʻohana nui ʻia ia no ka hoʻopaʻa ʻana i ke aniani o nā ʻāpana uila e like me ka emission tube, oscillation tube, ignition tube, magnetron, transistor, sealing plug, relay, integrated circuit lead line, chassis, shell, bracket, etc. pono e hoʻolikelike ʻia ka helu hoʻonui o ke aniani i koho ʻia a me ka huila. ʻO ka haʻahaʻa haʻahaʻa o ka ʻiʻo paʻa i hoʻāʻo ʻia e like me ka mahana hoʻohana. Pono e hoʻokō ʻia ka hoʻomaʻamaʻa wela kūpono i ke kaʻina hana e hōʻoia i ka maikaʻi o ka hana kiʻi hohonu. I ka hoʻohana ʻana i nā mea forging, pono e nānā pono ʻia kona paʻa ʻana o ka ea.
ʻO ka huila Covar ma muli o ka ʻike cobalt, ʻano kūʻokoʻa ka huahana.
Hiki ke hoʻopaʻa maʻalahi ʻia me ke aniani pūʻulu molybdenum, a ʻo ka ʻili maʻamau o ka mea hana e pono ai i ka uhi gula.
4J29 Hiki ke hana:
Loaʻa i ka alloy nā waiwai hana anu a me ka wela, a hiki ke hana ʻia i nā ʻano paʻakikī o nā ʻāpana. Eia nō naʻe, pono e pale ʻia ka hoʻomehana ʻana i nā ea i loko o ka sulfur. I ka ʻōwili anu, ke ʻoi aku ka nui o ke kahe anu o ka ʻōpala ma mua o 70%, e hoʻoulu ʻia ka anisotropy plastik ma hope o ka hoʻopili ʻana. I ka manawa o ka 10% ~ 15%, e ulu koke ka palaoa ma hope o ka annealing, a e hana pū ʻia ka anisotropy plastic o ka alloy. ʻO ka anisotropy plastic ka liʻiliʻi loa inā ʻo 60% ~ 65% ka nui o ke kānana hope a ʻo ka nui o ka palaoa ʻo 7 ~ 8.5.
4J29 mau waiwai wiliwili:
Hiki ke hoʻopaʻa ʻia ka huila me ke keleawe, ke kila, ka nickel a me nā metala ʻē aʻe e ka brazing, fusion welding, resistance welding, a me nā mea ʻē aʻe. ka māwae weld. Ma mua o ka hoʻopaʻa ʻia ʻana o ke aniani me ke aniani, pono e hoʻomaʻemaʻe ʻia, a ukali ʻia e ka mālama ʻana i ka hydrogen pulu wai a me ka mālama pre-oxidation.
4J29 Kaʻina hana lapaʻau ʻili: Hiki ke hoʻomaʻamaʻa i ka ʻili i ke one, polishing, pickling.
Ma hope o ka hoʻopaʻa ʻia ʻana o nā ʻāpana me ke aniani, pono e hoʻoneʻe ʻia ke kiʻi oxide i hana ʻia i ka wā e hoʻopaʻa ʻia ai no ka hoʻopili maʻalahi. Hiki ke hoʻomehana ʻia nā ʻāpana ma kahi o 70 ℃ i kahi hopena wai o 10% hydrochloric acid + 10% nitric acid, a pickled no 2 ~ 5min.
He maikaʻi ka hana electroplating o ka alloy, a hiki ke hoʻopaʻa ʻia i ke gula, kālā, nickel, chromium a me nā metala ʻē aʻe. I mea e maʻalahi ai i ka hoʻopaʻa ʻana a i ʻole ka hoʻopaʻa ʻana i ka wela ma waena o nā ʻāpana, ua uhi pinepine ʻia me ke keleawe, nickel, gula a me ka tin. I mea e hoʻomaikaʻi ai i ka conductivity o ke alapine kiʻekiʻe o kēia manawa a hōʻemi i ke kūpaʻa pili e hōʻoia i nā hiʻohiʻona cathode emission maʻamau, ua uhi pinepine ʻia ke gula a me ke kālā. I mea e hoʻomaikaʻi ai i ke kūpaʻa corrosion o ka hāmeʻa, hiki ke uhi ʻia ka nickel a i ʻole ke gula.
4J29 Hana ʻoki a wili ʻia:
ʻO nā hiʻohiʻona ʻokiʻoki o ka mea hoʻohui e like me nā mea o ka austenitic stainless steel. Ke hoʻohana ʻana i ka hoʻohana ʻana i ke kila kiʻekiʻe a i ʻole ka mea hana carbide, haʻahaʻa haʻahaʻa e ʻoki ʻoki. Hiki ke hoʻohana ʻia ka mea hoʻoluʻu i ka wā e ʻoki ai. He maikaʻi ka hana wili ʻana o ka alloy.
4J29 Nā kikoʻī nui:
4J29 paipu ʻole, 4J29 pā kila, 4J29 kila poepoe, 4J29 forgings, 4J29 flange, 4J29 apo, 4J29 paipu wiliwili, 4J29 paipu kila, 4J29 pahu pololei, 4J29 uea a me ka like me ka wiliwili mea, 4J29 poepoe keke, 4J29 poepoe keke, he 4J29 poepoe. pā, 4J29 nui poʻo, 4J29 kuʻekuʻe, 4J29 tee, 4J29 4J29 ʻāpana, 4J29 bolts a me nā nati, 4J29 mea hoʻopaʻa, etc.
