Ụdị Nickel Alloys ndị a na-ahụkarị
Nickel ga-adị mfe na ọtụtụ ọla dị ka ọla kọpa, chromium, iron, na molybdenum.Mgbakwunye nke nickel na ọla ndị ọzọ na-agbanwe njirimara nke alloy na-esi na ya pụta na enwere ike iji ya mepụta àgwà ndị a chọrọ dị ka mma corrosion ma ọ bụ nkwụsị oxidation, mmụba dị elu na-arụ ọrụ okpomọkụ, ma ọ bụ ọnụ ọgụgụ dị ala nke mgbasawanye ọkụ, dịka ọmụmaatụ.
Akụkụ ndị dị n'okpuru na-enye ozi gbasara nke ọ bụla n'ime ụdị nickel alloys ndị a.
Nickel-Iron Alloys
Nickel-iron alloys na-arụ ọrụ na ngwa ebe ihe onwunwe chọrọ bụ ọnụ ọgụgụ dị ala nke mgbasawanye ọkụ.Invar 36®, nke a na-erekwa ya na aha ahia nke Nilo 6® ma ọ bụ Pernifer 6®, na-egosipụta ọnụọgụ nke mgbasawanye thermal nke dị ihe dịka 1/10 nke ígwè carbon.Nkwụsi ike nke akụkụ a dị elu na-eme ka alloys nickel-iron bara uru na ngwa dị ka ngwa nha nkenke ma ọ bụ mkpanaka okpomọkụ.A na-eji alloys nickel-iron ndị ọzọ nwere nnukwu mkpokọta nickel na ngwa ebe akụrụngwa magnetik dị nro dị mkpa, dị ka ihe ngbanwe, inductor, ma ọ bụ ngwaọrụ nchekwa ebe nchekwa.
Nickel-ọla kọpa Alloys
Nickel-ọla kọpa alloys na-eguzogide ọgwụ corrosion site na mmiri nnu ma ọ bụ mmiri mmiri ma si otú ahụ chọta ngwa na ngwa mmiri.Dịka ọmụmaatụ, Monel 400®, nke a na-erekwa n'okpuru aha azụmaahịa Nickelvac® 400 ma ọ bụ Nicorros® 400, nwere ike ịchọta ngwa na sistemu ọkpọkọ mmiri, ogwe mgbapụta, na valvụ mmiri mmiri.Alloy a dị ka ihe kacha nta nke 63% nickel na 28-34% ọla kọpa.
Nickel-Molybdenum Alloys
Nickel-molybdenum alloys na-enye nnukwu nguzogide kemịkalụ na acid siri ike na ndị na-ebelata ihe ndị ọzọ dị ka hydrochloric acid, hydrogen chloride, sulfuric acid na phosphoric acid.Ngwakọta kemịkalụ maka alloy nke ụdị a, dị ka Alloy B-2®, nwere mkpokọta molybdenum nke 29-30% yana ntinye nickel dị n'etiti 66-74%.Ngwa gụnyere nfuli na valvụ, gaskets, arịa nrụgide, ndị na-agbanwe ọkụ, na ngwaahịa ọkpọkọ.
Nickel-Chromium Alloys
Nickel-chromium alloys bụ ihe dị oké ọnụ ahịa maka nguzogide corrosion ha dị elu, ike okpomọkụ dị elu, na elu ọkụ eletrik.Dịka ọmụmaatụ, alloy NiCr 70/30, nke a na-akpọkwa dị ka Ni70Cr30, Nikrothal 70, Resistohm 70, na X30H70 nwere ebe mgbaze nke 1380oC na ihe mgbochi eletrik nke 1.18 μΩ-m.Ihe ndị na-ekpo ọkụ dị ka na toasters na ọkụ ọkụ eletrik ndị ọzọ na-eji nickel-chromium alloys.Mgbe emepụtara ya n'ụdị waya, a na-akpọ ha Nichrome® waya.
