Nickel-based Alloy Yakashandiswa nePassivation
Mhando Dzakawanda dzeNickel Alloys
Nickel inosanganiswa nyore nyore nesimbi zhinji semhangura, chromium, iron, uye molybdenum.Kuwedzerwa kwe nickel kune mamwe masimbi kunoshandura maitiro eiyo alloy inoguma uye inogona kushandiswa kugadzira inodiwa hunhu seyakagadziridzwa corrosion kana oxidation kuramba, kuwedzera kwepamusoro-tembiricha kuita, kana kuderera coefficients yekuwedzera kupisa, semuenzaniso.
Zvikamu zviri pasi apa zvinopa ruzivo nezve imwe neimwe yemhando idzi dze nickel alloys.
Nickel-Iron Alloys
Nickel-iron alloys inoshanda mumashandisirwo apo chivakwa chinodiwa chiyero chakaderera chekuwedzera kwekupisa.Invar 36®, zvakare inotengeswa nemazita ekutengeserana eNilo 6® kana Pernifer 6®, inoratidza coefficient yekuwedzera kwekupisa iyo inenge 1/10 iyo yecarbon steel.Iyi dhigirii yepamusoro yekudzikama inoita kuti nickel-iron alloys inobatsira mumashandisirwo akadai semidziyo yekuyeresa chaiyo kana tambo dze thermostat.Mamwe nickel-iron alloys ane yakatonyanya kuwanda kwe nickel anoshandiswa mumashandisirwo uko akapfava magineti zvimiro zvakakosha, senge ma transformer, inductors, kana memory yekuchengetedza zvishandiso.
Nickel-Mhangura Alloys
Nickel-copper alloys inoshingirira mukuora nemvura ine munyu kana mvura yegungwa uye nekudaro inowana kushandiswa mukushandiswa kwemugungwa.Semuenzaniso, Monel 400®, zvakare inotengeswa pasi pemazita ekutengesa Nickelvac® 400 kana Nicorros® 400, inogona kuwana kushandiswa mumarine pombi systems, pombi shafts, uye mavharuvhu emvura yegungwa.Iyi alloy sehuwandu hwehuwandu hwe63% nickel uye 28-34% mhangura.
Nickel-Molybdenum Alloys
Nickel-molybdenum alloys inopa yakakwira makemikari kuramba kune yakasimba asidhi uye zvimwe zvinoderedza zvakaita sehydrochloric acid, hydrogen chloride, sulfuric acid, uye phosphoric acid.Kemikari yekugadzira alloy yemhando iyi, yakadai seAlloy B-2®, ine mutsara we molybdenum we 29-30% uye nickel concentration iri pakati pe66-74%.Zvishandiso zvinosanganisira pombi nemavharuvhu, gaskets, midziyo yekumanikidza, zvinopisa kupisa, uye zvigadzirwa zvepombi.
Nickel-Chromium Alloys
Nickel-chromium alloys anokosheswa nekukwirira kwawo kwegora, kusimba kwepamusoro-tembiricha, uye kukwirira kwemagetsi kuramba.Semuenzaniso, alloy NiCr 70/30, zvakare yakasarudzwa seNi70Cr30, Nikrothal 70, Resistohm 70, uye X30H70 ine nzvimbo yekunyunguduka ye 1380oC uye yemagetsi resistivity ye 1.18 μΩ-m.Zvinhu zvekudziyisa senge muma toaster uye mamwe magetsi anodzivirira kupisa anoshandisa nickel-chromium alloys.Kana yagadzirwa muwaya fomu dzinozivikanwa seNichrome® waya.
