Hāʻawi nā ʻāpana alloy Nickel 400 i ke kūpaʻa like ʻole i ka chloride stress corrosion cracking, ka lua wai kai, a me nā kaiapuni alkali caustic - nā kūlana kahi e hāʻule mālie a pōʻino nā kila kila. Ua ʻike mua mākou: ʻo ka hydraulic manifold i loko o kahi ʻōnaehana hoʻomalu o ke kai ʻĀkau i haki i 18 mau mahina-ʻaʻole mai ke kaomi, akā mai ka hoʻokomo ʻana o ka chloride lohi i ka micro-porosity i loko o kahi hale 316 maikaʻi ʻole. Ke hoʻololi nei i ka Nickel 400 alloy part geometry, me ka hoʻopaʻa paʻa ʻana a me ka hoʻomaha ʻana i ke koʻikoʻi ma hope o ka mīkini, hoʻolōʻihi ʻia ke ola lawelawe ma mua o 12 mau makahiki. ʻAʻole ia he hana theoretical. ʻO ia ka hilinaʻi i hōʻoia ʻia e ke kahua.
No ke aha e kū ʻokoʻa ai ʻo Nickel 400 i nā hoʻokūkū hoʻoweliweli honua maoli
ʻO Nickel 400 (UNS N04400, Monel 400) ʻaʻole ia he "kūpaʻa-corrosion." ʻAʻole koho. ʻO kona 67% nickel–30% copper base i hoʻolaʻa ponoʻī, adherent oxide layer e kūʻē i ka hoʻoheheʻe ʻia ʻana i loko o ka brine, hydrofluoric acid, a me ka sulfuric acid ma lalo o 70% ka hoʻopaʻa ʻana-ʻoiai ma nā mahana kiʻekiʻe. ʻAʻole like me nā kila stainless duplex, ʻaʻole ia e hōʻike i ka embrittlement sigma-phase ma hope o ka hoʻolaha lōʻihi ma luna o 500°F. ʻAʻole like me ka titanium, kūpaʻa ia i ka hoʻohaʻahaʻa ʻana i nā waikawa me ka ʻole o ka pale cathodic metala hanohano. Akā, koi ka palekana i ka pololei: porosity, intermetallic segregation, a i ʻole ke koʻikoʻi machining koena hiki ke hana i nā cell galvanic localized. ʻO ia ke kumu ʻaʻole lawa ka palapala hōʻoia maka wale nō. Pono ʻoe i ka hoʻomaʻamaʻa wela hiki ke ʻike ʻia, ke ʻano o ka palaoa i hōʻoia ʻia, a me ka pono o ka ʻili i hoʻopaʻa ʻia e Nital etch a me SEM cross-section analysis-ʻaʻole wale nā palapala wili.
Kahi i hāʻule ʻole ai ka hana maʻamau—a me nā ʻanuʻu ʻenekinia pololei
Hiki paha i kekahi ke hoʻopaʻapaʻa e hoʻonā ka pahu pahu Nickel 400 ma waho o ka papa i ka pilikia. Eia nō naʻe, ʻo ka hapa nui o nā noi paʻa kiʻekiʻe e koi ana i ka geometry hiki ʻole ke hoʻokō ma o ka huli maʻamau a wili wale paha. E noʻonoʻo i kahi hale pahu pahu piston pump no ka hoʻoheheʻe ʻana i ka ʻaila ma waho: ʻo nā kahawai hoʻoluʻu kūloko e hui ana ma nā kihi 47°, ʻokoʻa ka mānoanoa o ka pā mai 12 mm a 3.2 mm i loko o 50 mm o ka huakaʻi, a me nā wahi e hoʻopaʻa ʻia e koi ana iā Ra ≤ 0.4 µm. ʻO CNC maʻamau ma Nickel 400 i hoʻopaʻa ʻia ke kumu o ka paʻakikī o ka hana, ka hoʻohuli ʻana i ka mea hana, a me ka hoʻokaʻawale ʻana i ka wela—e alakaʻi ana i ka leakae o waho a me ka leaka sila mua. Hoʻoholo mākou i kēia ma ka hoʻohui ʻana i ka hoʻolei kālā no ke ʻano ʻupena kokoke (e hōʻemi ana i ka manawa mīkini e 65%), a ukali ʻia e ka wili like ʻole ʻelima me ka hāʻawi ʻana i ka coolant cryogenic a me ka hōʻoia CMM i ka hana i kēlā me kēia hoʻonohonoho. Ka hopena? ʻO ka paʻa ʻana o ka dimensional i loko o ± 0.015 mm ma waena o 300 mm ka lōʻihi—a ʻaʻohe hemahema i hōʻike ʻia ma nā kahua he 42 ma Norewai, UAE, a me Louisiana.
