ʻAʻole ʻae nā ʻāpana ʻoihana hana kiʻekiʻe i ka hoʻololi ʻana - ʻoi aku ka nui o ka hana ma lalo o 300 bar hydraulic pressure, 600 ° C exhaust gas exhaust, a i ʻole nā ʻaʻahu abrasive mau i ka lawelawe ʻaila. ʻO ia ke kumu i hoʻonui nui ʻia ai nā mea ʻenekinia ma Tier-1 pump OEM a me nā mea hoʻohui ʻōnaehana hydraulic i ka hana kuʻuna a huli i hale hana metala pauda metallurgy ʻAʻole ma ke ʻano he hāʻule, akā ʻo ia wale nō ke ala kūpono i ke kūpaʻa dimensional, microstructural consistency, a me ka hilinaʻi hana i nā ʻāpana cobalt-nickel e like me AMS 5387 pump houses a i ʻole T800 alloy nozzles.
No ke aha e lanakila ai ka Powder Metallurgy ma kahi e hāʻule ai ka mīkini hoʻokahi
Ua ʻike pinepine mākou: hoʻouna ka mea kūʻai aku i kahi kiʻi kiʻi waiwai GD&T no kahi plug cobalt alloy me 0.01 mm kūlana hoʻomanawanui ma nā puka makapō ʻeono-a manaʻo ʻia he ± 0.005 mm ka mana mānoanoa o ka pā ma kahi radius radius 120 mm. ʻO ka mīkini CNC mai ka billet paʻa? Hiki—akā, piʻi ka nui o nā ʻōpala ma luna o 40% ma muli o ka hoʻoikaika ʻana i ka hana, ka hoʻohuli ʻana i nā mea hana, a me ka hoʻolaha ʻana o micro-crack ma AMS 5387. ʻOi aku ka maikaʻi, akā, ʻoi aku ka maikaʻi o ka porosity i ka 100% ultrasonic screening—a ʻaʻole naʻe he hōʻoiaʻiʻo o ka hoʻopuehu carbide like ʻole.
ʻO nā alahaka o ka pauka metala i kaʻe. Ma ke kaomi ʻana i ka isostatically wela (HIP) i hoʻohui ʻia i mua o ka pauka Co-Ni-Cr-Mo, hoʻopaʻa mākou i kahi kokoke-theoretical density * ma mua o * ka mīkini hope. Ka hopena? ʻAʻohe puka o loko. ʻAʻohe ʻano like ʻole o ke kahe ʻana o ka palaoa. ʻAʻohe hoʻoheheʻe wela i ka wā mālama wela. A ʻo ka mea koʻikoʻi - ʻaʻole pono e wehe i 70% o nā mea maka e hiki ai i ke ʻano ʻupena. Ua ʻoki kekahi mea hana pauma ʻAmelika ʻĀkau i ka manawa alakaʻi e 36% a me ka huina o ke kumukūʻai no kēlā me kēia ʻāpana e 29% ma hope o ka hoʻololi ʻana mai ka hale paʻa i ka mīkini a hiki i ka HIP + hoʻopau i nā hale cylinder.
ʻEhā mau mea hiki ʻole ke kūkākūkā ʻia e pono ai ʻoe e hōʻoia
He oiaio hale hana metala pauda metallurgy ʻaʻole i wehewehe ʻia ma ka loaʻa ʻana o kahi paʻi paʻi-ua ana ʻia e ka paʻa ʻana o ka mālama ʻana i ʻehā mau kikowaena pili:
- Hiki ke ʻike ʻia nā mea maka: Pono kēlā me kēia pūʻulu o T800 a i ʻole AMS 5387 pauda e lawe i nā palapala wili piha-ʻaʻole wale i ka haku mele, akā i ka ʻike oxygen (<150 ppm), puunaue ka nui o nā ʻāpana (D50 = 15–25 µm), a me ka ʻikepili hoʻopaʻa paʻa. Hōʻole mākou i nā ʻāpana pauda me ka ʻole o nā ʻāpana HIP i hōʻoia ʻia e pili ana i kēlā me kēia helu wela.
- HIP kaʻina aʻo: ʻAʻole ʻo ke kaomi wale nō e hōʻoia i ka paʻa. Hoʻopaʻa kā mākou pōʻai HIP i 1150 ° C ma 150 MPa no 3 mau hola-a laila hoʻomaha ma ≤5 ° C / min ma lalo o argon. Wehe i ka 10°C a i ʻole 10 MPa, a pilikia ʻoe i ka hoʻopaʻa diffusion piha ʻole ma nā pilina ʻāpana.
- ʻO ka pono ma hope o ka HIP: Ua emi nā ʻāpana HIP me ka anisotropic—a hiki i ka 0.18% axially, 0.09% radial. Hoʻopiʻi kā mākou papahana CNC me ka hoʻohana ʻana i nā palapala hōʻemi i nānā ʻia e ka laser, ʻaʻole nā offsets generic. Pēlā mākou e paʻa ai ± 0.008 mm ma ka piston bore ID ma hope o ka wili hope ʻana.
- Ka hōʻoia hana ma mua o CMM: He mea ʻole ke ana hoʻonohonoho kūpono inā hāʻule ka ʻāpana i ka hoʻāʻo ʻana. Hoʻopaʻa mākou i kēlā me kēia hale pahu kaomi ma ka 1.5 × kaomi hana no 60 mau minuke-me ka hoʻopili ʻana i ka manawa maoli ma o ka hoʻopili kiʻi kiʻi kiʻi (DIC).
I ka wa e ku'i ai ka hoohehee ana-makini i ka PM maemae
Kū'ē kekahi mau ʻāpana i nā ala pauka maʻemaʻe. Pono ka wili o waho o ka pahu winch center i kahi papa waho T800-aʻe—akā, pono e hoʻopaʻa ke kumu i nā haʻawe haʻalulu me ka haki ʻole. Ma ʻaneʻi, hoʻokomo ʻia kā mākou ʻāpana kila i hoʻoheheʻe ʻia me ka hoʻoheheʻe ʻia ʻana o ka cobalt ma lalo o ka momi, a laila mālama ʻia ʻo HIP ma ke ʻano hoʻokahi. ʻOi aku ka ikaika o ka paʻa ma mua o 620 MPa—hōʻoia ʻia e ka paukū SEM/EDS. ʻO nā mea kūʻai i hoʻāʻo i ka pale ʻana i hōʻike mua i ka delamination ma hope o 4,200 pōʻai; Ua hala kā mākou ʻano hybrid i 18,500 mau pōʻai i ka hoʻāʻo luhi ʻekolu ʻaoʻao.
ʻAʻole kēia he manaʻo. ʻO ia ka mea e hiki ai iā mākou ke hoʻopuka i nā geometries maʻamau ʻole-e like me nā kumu pahū eccentrically bored me nā kahawai hoʻohuihui hoʻohui ʻia-e koi ʻia ʻelima hoʻonohonoho ʻokoʻa ma nā mea hana maʻamau. Mīkini mākou iā lākou ma nā hana ʻelua: HIP + hoʻopau ma kahi wili 5-axis me ka mea hana ola a me ka tilt B-axis.
He aha kāu e koi ai ma mua o kou hoʻokuʻu ʻana i ka PO
E nīnau i kāu mea hoʻolako i kēia mau nīnau ʻekolu-a hele aku inā ʻaʻohe kikoʻī o nā pane:
- “E hōʻike mai iaʻu i ʻekolu mau moʻolelo holo HIP hope loa no AMS 5387—e hōʻike ana i ka nui o ka pae wela, ka manawa noho, a me nā hōʻike metallography ma hope o ka pōʻai."
- "Pehea ʻoe e hōʻoia ai i ka loaʻa ʻole o ka micro-porosity ma lalo o 25 µm? ʻO X-ray CT anei, ka nānā ʻana i ka ultrasonic phase, a i ʻole ka ʻāpana luku?"
- “Inā hōʻike kaʻu kiʻi kiʻi i ka helu helu puʻe ASME B16.34 Class 900, he aha kāu protocol leak-test i hoʻopaʻa ʻia—a he aha kāu helu pass mōʻaukala?"
Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., hiki ke nānā ʻia kēlā mau lāʻau i loko o 2 mau hola. Hoʻohana kā mākou hoʻāʻo leak i ka helium mass spectrometry ma 1x design pressure no 120 kekona-pass rate: 99.87% ma luna o 14,200 mau ʻāpana i hoʻouna ʻia mai Q3 2022. Māhele mākou i nā dosiers nānā piha-ʻaʻole nā hōʻuluʻulu-me kēlā me kēia hoʻouna.
No nā ʻāpana koʻikoʻi, ʻaʻole pili ka metallurgy pauka i ka hoʻemi ʻana i ke kumukūʻai. E pili ana i ka hoʻopau ʻana i nā ʻano hemahema ma mua o ke komo ʻana i kāu laina hui. Inā koi kāu papahana hou iā AMS 5387, T800, a i ʻole nā ʻāpana kikoʻī kiʻekiʻe-alloy ʻē aʻe kahi i hiki ʻole ke kūkākūkā ʻia ka geometry, ka pono, a me ka hoʻihoʻi hou ʻana - pono ʻoe ma mua o kahi hale hana metala pauda metallurgy. Pono ʻoe e mālama i kēlā me kēia helu wela e like me ka manamana lima, kēlā me kēia pōʻai HIP e like me ke kaʻina hana, a me kēlā me kēia hōʻike CMM e like me kahi palapala kānāwai. ʻO ia ke kumu. ʻO nā mea liʻiliʻi e hōʻemi i kou manawa hana, kāu mau palapala hōʻoia, a me kou inoa.
