NiCu 400 NiCu Alloy

ʻO NiCu 400 kahi huila nickel-copper (e pili ana i 67% Ni - 23% Cu) i kū i ka wai kai a me ka mahu ma nā wela kiʻekiʻe a me ka paʻakai a me nā hopena caustic. ʻO Alloy 400 kahi mea hoʻoheheʻe paʻa paʻa i hiki ke paʻakikī wale i ka hana anu. Hōʻike kēia nickel alloy i nā hiʻohiʻona e like me ke kūpaʻa corrosion maikaʻi, maikaʻi weld-hiki a me ka ikaika kiʻekiʻe. ʻO ka haʻahaʻa haʻahaʻa i loko o ke kahe wikiwiki ʻana i ka brackish a i ʻole ka wai kai i hui pū ʻia me ke kūpaʻa maikaʻi loa i ka pohā ʻana o ke koʻikoʻi-corrosion i ka nui o ka wai maʻemaʻe, a ʻo kona kūʻē ʻana i nā ʻano ʻino like ʻole i alakaʻi i kona hoʻohana ākea i nā noi kai a me nā mea hoʻonā chloride non-oxidizing ʻē aʻe. ʻO kēia nickel alloy he mea kūʻokoʻa i ka hydro-chloric a me ka hydro-fluoric acid i ka wā e hoʻopau ʻia ai. E like me ka mea i manaʻo ʻia mai kona ʻike keleawe kiʻekiʻe, ua hoʻouka koke ʻia ka alloy 400 e ka nitric acid a me nā ʻōnaehana amonia.

NiCu 400 mea nui mechanical waiwai ma subzero wela, hiki ke hoʻohana 'ia i loko o ka mahana a hiki i 1000 ° F, a me kona hehee ana o 2370-2460° F. Eia naʻe, Alloy 400 mea haʻahaʻa i ka ikaika i loko o ka annealed kūlana no laila, he ano o ka huhu. hiki ke hoʻohana ʻia e hoʻonui i ka ikaika.

Nā hiʻohiʻona o NiCu 400

  • Kūleʻa i ka wai kai a me ka mahu i nā wela kiʻekiʻe
  • Kūleʻa maikaʻi loa i ka wai paʻakai a i ʻole ka wai kai
  • Kūleʻa maikaʻi i ke koʻikoʻi i ka pohā ʻana i ka wai maʻemaʻe
  • Kūʻē kūʻē i ka hydro-chloric a me ka hydro-fluoric acid ke hoʻopau ʻia lākou
  • Kūʻē maikaʻi i ka paʻakai kūʻokoʻa a me ka paʻakai alkaline a me ke kūpaʻa kiʻekiʻe i ka alkali
  • Ke kū'ē i ka chloride i hoʻoulu ʻia i ke koʻikoʻi ʻinoʻino
  • ʻO nā waiwai mechanical maikaʻi mai nā mahana sub-zero a hiki i 1020° F
  • Hāʻawi i kahi kū'ē i ka hydro-chloric a me ka sulfuric acids i nā mahana haʻahaʻa a me nā ʻike, akā kakaikahi ka mea i koho ʻia no kēia mau ʻakika.

He moʻolelo lōʻihi kēia o ka hoʻohana ʻana ma ke ʻano he mea pale i ka corrosion, mai ka hoʻomaka ʻana o ke kenekulia 20 i ka wā i hoʻomohala ʻia ai ma ke ʻano he hoʻāʻo e hoʻohana i ka ʻohe nickel maʻiʻo keleawe kiʻekiʻe. ʻO ka nickel a me ke keleawe ma loko o ka ʻohe i loko o ka ratio kokoke i hōʻike mua ʻia i kēia manawa no ka alloy.

ʻO NiCu 400 ke kūpale ʻana

NiCu Alloy 400ʻaneʻane pale ʻole i ka chloride ion stress corrosion ma nā kaiapuni maʻamau. ʻO ka maʻamau, ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion i ka hōʻemi ʻana i nā kaiapuni, akā ʻilihune i nā kūlana oxidizing. ʻAʻole pono ia i ka hoʻokahe ʻana i nā waikawa, e like me ka waikawa nitric a me ka nitrous. Eia nō naʻe, kūpaʻa ia i ka hapa nui o nā alkalis, nā paʻakai, nā wai, nā huahana meaʻai, nā mea kūlohelohe a me nā kūlana o ka lewa i nā mahana maʻamau a kiʻekiʻe.

Hoʻouka ʻia kēia huila nickel i nā kinoea lawe sulfur ma luna o 700° F a hoʻouka ʻia ka sulfur hoʻoheheʻe ʻia i ka alloy ma nā mahana ma kahi o 500° F.

Hāʻawi ʻo NiCu 400 e pili ana i ke kūpaʻa corrosion e like me ka nickel akā me ke kiʻekiʻe kiʻekiʻe o ka hana ʻana a me nā mahana a me ke kumu kūʻai haʻahaʻa ma muli o kona hiki ke hana ʻia.

Hana NiCu 400

Hiki ke hoʻopili maʻalahi ʻia ʻo NiCu Alloy 400 e ke kinoea-tungsten arc, gas metala arc a i ʻole nā ​​​​kaʻina hana pale metala me ka hoʻohana ʻana i nā metala hoʻopiha kūpono. ʻAʻohe pono no ka mālama ʻana i ka wela ma hope o ka weld, akā naʻe, ʻo ka hoʻomaʻemaʻe ʻana ma hope o ka wili ʻana he mea koʻikoʻi ia no ka pale ʻana i ka corrosion maikaʻi loa, inā ʻaʻole, aia ka pilikia o ka haumia a me ka embrittlement.

Hiki ke hana ʻia nā mea hana i hoʻopau ʻia i ka nui o nā ʻano mīkini i ka wā e hoʻomalu pono ʻia ai ka nui o ka hana wela a i ʻole ke anu a me ke koho ʻana i nā lāʻau wela kūpono.

E like me ka hapa nui o nā nickel alloys, ʻo NiCu 400 ka mea paʻakikī i ka mīkini a e hana paʻakikī. Eia naʻe, hiki ke loaʻa nā hopena maikaʻi loa inā hana ʻoe i nā koho kūpono no ka mea hana a me ka mīkini.
