Iyi yendarira-nickel alloy ine zvakawanda inoshandisa
Cupronickel (inonziwo "cupernickel" kana mhangura-nickel alloy) inoreva boka remhangura-nickel alloys inoshandiswa munzvimbo dzomumunyu pamusana pemakumbo avo asingagadzirwi.
Iyo yakawanda inonyanya kukonzerwa ne cupronickel ndeyi: 90/10 Cupro-nickel (copper-nickel-iron) kana 70/30 Cupro-nickel (copper-nickel-iron)
Izvi zvinyorwa zvinoshanda zvakanaka, zvinoshandiswa nyore nyore uye zvinonzwisisika zvisingabatsiri kuora mwoyo.
Cupronickel inopesana ne biofouling, crevice corrosion, stress corrosion cracking uye hydrogen embrittlement.
Chengetedza kusiyana pakati pekudzivirira kwehurosi uye simba zvinowanzosarudza kuti ibhii yegorosi inoshandiswa pane imwe shanduro.
History of Cupronickel
Cupronickel yakagadzirwa uye yakashandiswa kwemakore anopfuura chiuru. Kushandiswa kwaro kwokutanga kuzivikanwa kwaiva kuChina munenge muna 300 BCE. Zvinyorwa zveChinese zvinotsanangura nzira yekuita "mhangura mutsvuku," iyo inosanganisira kupisa nekusanganisa mhangura, nickel, uye saltpeter.
Cupronickel yaishandiswa zvakare kuita mari yechiGiriki. Gare gare kuEurope "kuvezve" kweEurope kwekatekeriki yaisanganisira masayendisiti ekuedza.
Iyo shanduro yakashandiswa neUnited States Mint kuita zvikamu zvitatu zvezana uye zvikamu zvishanu kubva muzana munguva yeHondo yeVanhu. Mari yacho yakanga yambove yakagadzirwa nesirivha, iyo yakasara munguva yehondo. Kwemakumi emakumi apfuura, kupfeka kana kupfeka paAmerica makumi mashanu-zana, makota uye dimes zvakagadzirwa ne cupberickel.
Iko kune mari yakawanda inopararira, kana isiri kushandiswa ikozvino, iyo inoshandisa cupronickel kana yakaitwa ne cupronickel. Izvi zvinosanganisira Swiss franc, iyo 500 ne100 inopamba zvikamu muSouth Korea uye American Jefferson nickel.
Kurwisana Kurwisana kweChitronickel
Cupronickel inongorwisana nehuroti mumvura yegungwa, ichiita kuti ive senzi inokosha yekushandisa marita.
Iri jira rinokwanisa kurwisa kukora mumvura yegungwa nokuti simba rayo re electrode harisi rekurerekera munzvimbo dzakadaro. Somugumisiro, hazvizogadziri masero e electrolytic kana akaiswa pedyo pedo nedzimwe simbi mukati me electrolyte, iyo ndiyo iyo inokonzera galvaniic corrosion.
Mhangurawo inowanzoita mhepo yakadzivirira yakasviba pamusoro payo painoiswa mumvura yegungwa, iyo inodzivirira simbi kuti irege kuora.
Applications for Cupronickel
Cupronickel ine zvakawanda zvakashandiswa zvekushandisa. Mune zvimwe zviitiko, iyo inokosha nokuda kwesimba rayo uye kurwisa-kupikisa. Mune zvimwe zviitiko, inokosha nokuda kwechirairiro yechirivha uye rusina-rusina kupenya. Mimwe mienzaniso yekushandiswa kwekatekeriki inosanganisira:
- midziyo yevhenekeri yemhepo, magetsi emvura, uye evaporator inoshandiswa mumagetsi emagetsi uye zvinomera zve dealination
- mapapiro anotakura mvura yegungwa kumoto maoko, kunotonhorera zvirongwa zvemvura uye kutakura zvigadzirwa zvehutsanana
- kuputira mapuranga emapuranga
- dzimba iri pasi pemvura
- cabled cables tubes for hydraulic and pneumatic lines
- fasteners, crankshafts, hulls nedzimwe shandiswa dzegungwa zvinoshandiswa muzvikepe
- sirivha-mavara ekupararira mari
- sirivha-plated cutlery
- mishonga yemakirini
- motokari zvikamu
- zvishongo
- cylinder cores mu-high-lock locks
Cupronickel ine zvakawanda zvakasiyana siyana zvekushandiswa mu cryogenics, sezvo ine yakanaka yekutengesa kwemafuta pane zvakanyanya kutonhora.
Zvinyorwa zvakare zvaishandiswa kupfeka majekete emakumbo munguva yekupedzisira kwezana remakore rechi19, asi yakaita kuti imwe simbi inoputika mukati, uye yakasimudzwa zvakare.
