Alloy-ku-saleysan Nickel Lagu Codsaday Passivation
Noocyada Caadiga ah ee Alloys Nickel
Nickelku wuxuu si fudud ugu milmayaa biraha badankooda sida naxaasta, chromium, iron, iyo molybdenum.Ku darida nikkel ee biraha kale waxay bedeshaa sifooyinka daawaha ka soo baxa waxaana loo isticmaali karaa in lagu soo saaro sifooyin la doonayo sida hagaajinta daxalka ama caabbinta oksaydhka, korodhka waxqabadka heerkulka sare, ama isugeynta hoose ee ballaarinta kulaylka, tusaale ahaan.
Qaybaha hoose waxay soo bandhigayaan macluumaadka ku saabsan mid kasta oo ka mid ah noocyadan alwaaxyada nikkel.
Nikel-Iron Alloys
Alloys-birta nickelku waxay ka shaqeeyaan codsiyada halka hantida la doonayo ay tahay heerka hoose ee ballaarinta kulaylka.Invar 36, oo sidoo kale lagu iibiyay magacyo ganacsi oo ah Nilo 6® ama Pernifer 6®, waxay soo bandhigaysaa isku-dhafka balaadhinta kulaylka oo qiyaastii 1/10 ka ah birta kaarboonka.Heerkan sare ee xasilloonida cabbirku wuxuu ka dhigayaa daawaha nikkel-birta faa'iido u leh codsiyada sida qalabka cabbirka saxda ah ama ulaha kulaylka.Alloys kale oo nikkel-iron ah oo leh xaddi badan oo nikkel ah ayaa loo isticmaalaa codsiyada halka sifooyinka magnetic jilicsan ay muhiim u yihiin, sida transformers, inductors, ama qalabka kaydinta xusuusta.
Nickel-Copper Alloys
Alloys-ka nickel-copper waxay aad ugu adkaysanayaan daxalka biyaha milixda ah ama biyaha badda oo sidaas awgeed waxay helaan codsiga codsiyada badda.Tusaale ahaan, Monel 400®, oo sidoo kale lagu iibiyo magacyada ganacsiga Nickelvac® 400 ama Nicorros® 400, waxay ka heli kartaa codsiga hababka dhuumaha badda, shaftyada bamka, iyo tubooyinka biyaha badda.Alloyskan ugu yaraan 63% nikkel iyo 28-34% naxaas ah.
Nickel-Molybdenum Alloys
Alloys-ka nickel-molybdenum waxay bixiyaan iska caabin sare oo kiimiko ah asiidh adag iyo kuwa kale ee yareeya sida hydrochloric acid, hydrogen chloride, sulfuric acid, iyo phosphoric acid.Qurxinta kiimikaad ee daawaha noocaan ah, sida Alloy B-2®, waxay leedahay uruurinta molybdenum 29-30% iyo fiirsashada nikel inta u dhaxaysa 66-74%.Codsiyada waxaa ka mid ah bambooyin iyo valves, gaskets, weelasha cadaadiska, kulaylka beddelayaasha, iyo alaabta tuubooyinka.
Nikel-Chromium Alloys
Alloys-ka nickel-chromium waxaa lagu qiimeeyaa iska caabbinta daxalka sare, xoogga heerkulka sare, iyo iska caabbinta korantada sare.Tusaale ahaan, Alloy NiCr 70/30, oo sidoo kale loo qoondeeyay sida Ni70Cr30, Nikrothal 70, Resistohm 70, iyo X30H70 waxay leedahay bar dhalaalaysa 1380oC iyo iska caabin koronto oo ah 1.18 μΩ-m.Walxaha kuleyliyaha sida toasters-ka iyo kuleyliyeyaasha kale ee iska caabbinta korantada ayaa isticmaala aloysyada nikkel-chromium.Marka lagu soo saaro qaab silig ah waxaa loo yaqaan silig Nichrome®.
