ʻO ka Papa Foundry Reality
E kamaʻilio kāua. Me huila cobalt, ʻoi aku ka nui o nā māka kiʻekiʻe i ka chromium a me ka tungsten e like me Stellite 6 a i ʻole 21, ʻo ka wela wela he hula ma ka ʻaoʻao o ka pahi. He ʻoluʻolu loa, a loaʻa iā ʻoe nā pani anu a hoʻopiha piha ʻole i nā ʻāpana lahilahi. Wela loa, a pilikia ʻoe i ka ulu ʻana o ka palaoa a me ka hoʻokaʻawale ʻana i ka carbide, e hoʻopau loa i nā waiwai ʻaʻahu āu e uku nei. Ua ʻike au i ka puka ʻana mai o nā ʻāpana mai loko mai o ka ʻeleʻele me ka maikaʻi loa, ʻaʻole naʻe i hāʻule mua i ka lawelawe ʻana no ka mea ua pau ka hana hoʻoheheʻe ʻana i kekahi mau degere a ʻaʻole i mālama ʻia ka helu hoʻomaha. He mea ia e hoʻopaʻi i ka manaʻo.
ʻO kēia kahi e pili ai ka moʻopuna o ka hale hana. ʻO kahi hale kūʻai i ninini ʻia i ka hao hao e hakakā. Pono ʻoe i ka hoʻoheheʻe ʻana o ka lewa, pinepine i ka argon a i ʻole vacuum, i mea e pale ai i ka oxidation o nā mea reactive e like me ka chromium. Hoʻomanaʻo wau i kahi papahana i nā makahiki i hala aku nei kahi i loaʻa ai iā mākou kekahi poʻe cast huila cobalt nā sila turbine mai kahi mea hoʻokumu generalist. Ua hoʻokō ʻia nā kikoʻī dimensional, akā i ka hoʻāʻo ʻana, hōʻike lākou i ka oxidation catastrophic i ka mahana. ʻO ka mea hewa? ʻO nā ʻāpana o ka ʻohi ʻana o ka oxygen i ka wā o ka ninini ʻana i hana ai i nā ʻokikene palupalu ma nā palena o ka palaoa. Ua hoʻolei ʻia ka ʻāpana, akā pono ʻole ka hana.
Hoʻopili kēia me nā mea āu e ʻike ai mai nā loea i noho me kēia mau mea. E lawe iā Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). ʻO kā lākou mau makahiki ʻekolu i ka nānā ʻana i ka pūpū a me ka hoʻolei kālā ʻana no nā alloys kūikawā ʻaʻole ia he laina kūʻai. No a mea hoʻohuihui kobalt, ʻo ka ʻōnaehana mold shell (pinepine i ka zirconia-based ceramic) a me nā pōʻai de-waxing a me ke kī pū ʻana he ʻāpana o ka microstructure hope loa o ka mea. ʻO ka loaʻa mau ʻana o ia mea ka ʻokoʻa ma waena o kahi ʻāpana a me kahi paona pepa. ʻO kā lākou pūnaewele, https://www.tsingtaocnc.com, kikoʻī i kā lākou hana me kēia mau mea hao, a ʻo ka hōʻiliʻili ʻana o ia ʻike kikoʻī kaʻina hana e wehewehe i ka hiki, ʻaʻole ka papa inoa o nā inoa waiwai.
Mīkini: Kahi e hui ai ʻo Theory i ka mea hana
Inā he hānau maʻalahi ka hoʻolei ʻana, he kaua hoʻomalu ʻia ka mīkini. ʻO ka manaʻo paʻakikī o nā mea he nui nā huila cobalt he kaao. ʻAʻole hiki iā ʻoe ke hoʻokokoke iā ia e like me ka mīkini kila. ʻO kahi mea hana pohihihi, kahi helu hānai hewa, a ua hoʻopaʻakikī koke ʻoe i ka papa o ka ʻili, i hiki ʻole ai ke ala aʻe a hiki ke ʻoki i kāu hoʻokomo carbide. Pono e hemo ka swarf ma ke ʻano he puʻupuʻu wela, ʻālohilohi, mau. Inā loaʻa ʻoe i ka lepo a i ʻole nā ʻāpana ʻāpana, ua nalowale ʻoe.
ʻO ka hoʻonohonoho nā mea a pau. ʻAʻole hiki ke kūkākūkā ʻia ka rigidity. ʻO kēlā me kēia kamaʻilio ʻana a i ʻole deflection e hoʻopau koke i ka hāmeʻa. Ua aʻo mākou i kēia ma ke ala paʻakikī e hoʻāʻo e wili i kahi ʻaoʻao paʻakikī ma kahi noho Stellite. Ua hoʻohana mākou i kahi papahana CNC maʻamau no ke kila, e hoʻemi wale i ka wikiwiki a me nā hānai. He pōʻino. He mau minuke ka mea paahana, a ua nahae ka pauku. ʻAʻole wale nā māmā māmā o ka hoʻonā; ʻO ka noʻonoʻo hou ʻana: nā geometries kūikawā (rake maikaʻi, nā ʻaoʻao ʻoi), ka mea hoʻoluʻu kiʻekiʻe i kuhikuhi pololei ʻia ma ka ʻoki ʻoki no ka mālama ʻana i ka wela a me ka haki ʻana i nā ʻāpana, a me nā ala wili trochoidal e hoʻomau mau i ka hoʻopili. He kaʻina hana subtractive e koi ana i ka ʻike hoʻohui.
ʻO kēia ka waiwai o nā hale kūʻai hoʻohui. ʻO kahi keʻena e hāʻawi ana i ka hoʻolei ʻana a me ka mīkini CNC ma lalo o ka hale hoʻokahi, e like me QSY, loaʻa kahi pono kūpono no huila cobalt ʻāpana. ʻAʻole ʻike ka poʻe mīkini ma laila i kahi pohihihi, paʻakikī paʻakikī loa e hiki mai ana i ko lākou puka. Hoʻopili pinepine ʻia lākou mai ka pae kumu, hoʻomaopopo i ke koena o ke koena o ka ʻāpana mai ka hoʻolei ʻana, nā ʻāpana paʻakikī i manaʻo ʻia, a me nā hoʻokomo ʻana. Hāʻawi kēia hoʻomau i ka loiloi kaʻina hana hiki ʻole ke hoʻolei ʻia a me ka mīkini. He pololei ka puka manaʻo: ʻike ka mīkini i kahi ʻāpana o ka paʻakikī i manaʻo ʻole ʻia a hiki ke hoʻi i ka hale hana e kūkākūkā ai i ka ninini ʻana a i ʻole ka mālama wela no kēlā pūʻulu.
Ka Alloy Choice Trap
ʻAʻole nā mea a pau nā huila cobalt hana ʻia like, a kuhikuhi ka palapala noi i ka māka ma nā ʻano ʻike ʻole ʻia. ʻO Stellite 6 ka mea hana no ka pale ʻana i ka lole maʻamau. Hāʻawi ʻo Stellite 12 i ka ʻikepili carbide kiʻekiʻe no ka ʻaʻahu abrasive. A laila, loaʻa iā ʻoe nā māka e like me Haynes 25 (L-605) a i ʻole 188, i hoʻolālā ʻia no ka ikaika kiʻekiʻe-mehana a me ka pale ʻana i ka oxidation i ka aerospace, me nā ʻano machining a me nā ʻano wili. ʻO ka wehewehe ʻana i ka hewa he hewa nui.
Ke hoʻomanaʻo nei au i kahi hihia kahi i koi ai ka mea kūʻai aku e hoʻohana i ka Stellite 6 no kahi noho kiʻekiʻe o ka wela wela no ka mea he waiwai kā lākou. Ua hana maikaʻi ʻole ia, e ʻeha ana i ka lole oxidative a me ka liʻiliʻi deformation. ʻAʻole ka maikaʻi o ka mea i pilikia; ʻo ka ʻohana alloy wale nō ia no kēlā hui pū ʻana o ka wela a me ka lewa. Ua hoʻololi mākou i ka nickel-based alloy me kahi alumini oxide-forming element, nāna i hoʻoponopono i ka pilikia. ʻO ka haʻawina? ʻO nā ʻāpana kobalt ʻAʻole ia he hopena monolithic no ka wela a me ka paʻakikī. ʻO kā lākou matrix (inā he kobalt-waiwai a ʻoi aku ka paʻakikī) a me ka hana carbide e wehewehe i kā lākou niche.
ʻO kēia kahi e koʻikoʻi ai ka nui o nā mea hoʻolako. He hui e papa inoa ana nā mea hoʻohuihui kobalt, nickel-based alloys, etc. e hōʻailona ana i ka hoʻomaopopo ʻana he hoʻoholo ʻenehana kumu ke koho ʻana. ʻAʻole lākou e koi wale i nā mea i loaʻa iā lākou; Ua mākaukau lākou e kamaʻilio e pili ana i ka pane kūpono ʻana o ka pahu kobalt, a inā ʻoi aku ka maikaʻi o kahi superalloy ʻē aʻe. Hānau ʻia kēlā ala kūkākūkā mai ka ʻike ʻana i nā kūleʻa a me nā hemahema ma nā noi.
Welding and Repair: The Art of the Possible
Hoʻoponopono a kūkulu hou ʻia paha huila cobalt ʻO nā ʻāpana ma o ka welding ʻo ia kona honua kūikawā. ʻO ia ke ala ʻoi loa ke kumu kūʻai e hoʻolōʻihi ai i ke ola o kahi ʻāpana nui a pipiʻi e like me ka lau turbine a i ʻole ka wili extrusion. Akā, ua piha i nā pitfalls. Ke pohā nei ka ʻenemi mua, ʻo ka pohā wela paha i ka wā paʻa a i ʻole ka pohā koʻikoʻi mai ka hoʻokomo wela o ka wahi.
ʻO ka hoʻomaʻamaʻa maʻamau ka hoʻohana ʻana i ka metala hoʻopihapiha hoʻopihapiha hoʻohālikelike, akā naʻe, ʻoi aku ka mea nui o ka pre-heat a me ka interpass temperature control. Ke hana nei ʻoe i kahi wai hoʻoheheʻe liʻiliʻi. ʻO ka wikiwiki loa, a hoʻopaʻa ʻoe i nā pilikia. Ua lohi loa, a lilo ka wahi i hoʻopilikia ʻia i ka wela, hiki ke hoʻololi i nā waiwai o ka metala kumu. Ua hoʻohana au i mau hola ma kahi wili hoʻoponopono no ka make nui ʻana, e lohe wale i ka ping weliweli o kahi māwae e puka mai ana i ka wā e maʻalili ai, no ka mea, ua lele mākou i ka mālama ʻana o ka wela ma hope o ka wela i loko o kahi pale pale.
ʻO ka hoʻoponopono kūleʻa pinepine e iho i lalo i ka ʻike ʻohana. Hoʻokumu ka poʻe welder maikaʻi i ka manaʻo no ka wai a me ke kala o ka puddle. ʻAʻole kēia he mea āu e loaʻa ai mai kahi ʻikepili. ʻO ia ke kumu e kūkulu ai nā hana lōʻihi i ia ʻike ʻoihana. Ke haʻi aku nei kahi hui e like me QSY i 30 mau makahiki i ka hoʻolei ʻana a me ka mīkini, ʻo ia ka palena manawa ua ʻike lākou a hana paha i kā lākou mahele o ka hana hoʻoponopono a me ka hana hou ʻana i kēia mau mea paʻakikī, e hōʻiliʻili ana i nā lula i kākau ʻole ʻia e hoʻokele i ka kūleʻa.
E nana ana i ka Halepalaoa
ʻO ka hope, hilinaʻi a huila cobalt 'o ia ho'i ka hilina'i i kona microstructure. ʻO ka palapala hōʻoia no ke kemika ka ʻaoʻao mua o ka moʻolelo. Ua kākau ʻia ka moʻolelo maoli i ka nui o ka palaoa, ka māhele ʻana a me ka morphology o nā carbide, a me ka nele o nā hemahema. Pono ʻoe e nānā iā ia. Hiki i kahi macro-etch ke hōʻike i nā pilikia o ka ninini ʻana, ka emi ʻana, a i ʻole ke pani anu. Hōʻike ʻo Microscopy ma 100x a i ʻole 500x iā ʻoe inā hoʻopuehu like ʻia nā carbide paʻakikī a hoʻopaʻa ʻole ʻia i loko o nā pūnaewele ʻuʻuku.
ʻO kēia ka loiloi hope loa, ʻaʻole hiki ke kūʻai ʻia. Ua hōʻole mākou i nā pūʻulu i hala i nā loiloi nui a me nā kemika no ka mea ua hōʻike ka metallography i ka hoʻokaʻawale dendritic koʻikoʻi. ʻAʻole i like ʻole ka ʻāpana a hāʻule koke. ʻO kēia pae o ka nānā ʻana he ʻāpana o ka pūʻolo ke hana ʻoe me nā mea hoʻolako koʻikoʻi. ʻO ia ka ʻokoʻa ma waena o ke kūʻai ʻana i kahi mea a me ke kūʻai ʻana i kahi hōʻoia hana. ʻO ka mānoanoa, ke kani, ka microstructure - ʻo ia nā mea i ʻike ʻia o nā kaʻina hana āpau i kamaʻilio mua ʻia.
No laila, i ka loiloi ʻana i kahi kumu, e ʻimi i nā hōʻike o kēia mana holistic. Hiki iā lākou ke hāʻawi i ka hoʻolei wale ʻana, akā i ka moʻolelo ma hope o ia? Hiki iā lākou ke kūkākūkā i nā pihi hoʻomaʻamaʻa wela, nā helu hoʻomaha, a me nā pahuhopu microstructural? ʻO ka hiki ke hana pēlā, i hānau ʻia mai nā makahiki he nui o ka nānā ʻana e like me ka ʻike ʻana me nā hui e like me Qingdao Qiangsenyuan Technology, ʻo ia ka mea e hoʻokaʻawale ai i kahi mea kūʻai ʻāpana mai kahi hoa hana maoli no ka koi ʻana. huila cobalt nā noi. ʻO ka maikaʻi wale nō ka mea e like me ke kaʻina hana, mai ka wai a hiki i kahi ʻāpana.
