Ii-alloy ezisekelwe kwi-nickel ziintsimbi ezenziwe ngobunjineli eziqulethe i-nickel njengento ephambili, zihlala zidlula i-50% ngobunzima. Ulwakhiwo lwazo oluncinci luvumela amandla angaqhelekanga oomatshini, ukumelana nokuqhekeka, kunye nokuzinza kwe-oxidation ukuya kuthi ga kwi-800°C. Ezi mpawu zenza ii-alloy ezisekelwe kwi-nickel zibe yimfuneko kwiinjini zejethi, ii-turbine zegesi, izityalo zamandla enyukliya, kunye nee-reactors zeekhemikhali apho kukho ubushushu obugqithisileyo kunye neendawo ezibolayo. Kwi-aerospace, ii-superalloy ezifana ne-Inconel kunye ne-Nimonic zibonelela ngokumelana nokudinwa ngexesha lokujikeleza kobushushu ngokukhawuleza. Kwi-chemical processing, ii-alloy zigcina ukusebenza kwi-media ene-acid eninzi okanye i-chlorine.

Indima ye-Alloying Elements: I-Iron, i-Nickel, i-Chromium, kunye neNgaphaya kwayo
Izongezo zezinto ezisisiseko zichaphazela ngokuthe ngqo ukusebenza kwezinto kunye nokumelana nokugqwala. Umxholo weChromium oqala kwi-19% ukuya kwi-23% uvumela ukwakheka komaleko we-oxide okhuselayo oqhubekayo, onyusa kakhulu ukumelana nezinto ezigqwala kwaye uphucula ubomi obude kwintsimbi engagqwaliyo kunye nee-superalloys. I-Nickel izinzisa isakhiwo sekristale kwaye yonyusa ukumelana nobushushu, ngakumbi kwiinkqubo ze-iron-nickel-chromium alloy. Ukongezwa kweMolybdenum, kumanqanaba afikelela kwi-9%, kwandisa ngakumbi ukumelana nokugqwala kwemigodi kunye ne-cravice okuxhaphakileyo emanzini olwandle nakwiindawo ezinoburhalarhume beekhemikhali. I-iron inegalelo kuzinzo loomatshini ngokuqinisa isisombululo kwaye ibonelela ngempumelelo yeendleko kwiindidi ezininzi.
Ukubaluleka kokuQinisekiswa koBume obuchanekileyo beZinto ezisisiseko
Ukusebenza, Ukuthobela, kunye Nokuphila Ixesha Elide
Idatha echanekileyo yokwakheka kwezinto ezisisiseko iqinisekisa ukuba ii-alloys ezisekelwe kwi-nickel ziyahlangabezana nemigangatho yoomatshini kunye nokhuseleko kwi-aerospace kunye nokuveliswa kwamandla. Umlinganiselo wentsimbi, i-nickel, kunye ne-chromium olawulwa ngokuqinileyo (umz., 60–75% Ni, 19–23% Cr) uchaphazela ngokuthe ngqo amandla okutsalwa kunye nokumelana nokuqhekeka kwi-700–1100°C. Uhlalutyo olungachanekanga lunokubangela ukuqhekeka okungalindelekanga, ukulahleka kobungqingqwa bobushushu obuphezulu, okanye ukusilela okukhulu kokugqwala kwimidiya enamandla. Ukuqinisekiswa komgangatho kunye nokulandeleka kuxhomekeke ekuqinisekisweni okuchanekileyo kwezinto ezisisiseko ukuze kuthotyelwe imithetho kunye nokuqinisekiswa kwewaranti.
Umxholo weChromium kunye nokumelana nokugqwala
I-Chromium kwi-19–23% yenza ifilimu ye-Cr₂O₃ oxide eqhubekayo, ebalulekileyo ekumelaneni nee-asidi, ii-caustics, kunye ne-oxidation yobushushu obuphezulu. Ukumelana nokugqwala kwentsimbi engagqwaliyo kufuna ipesenti encinci ye-chromium: ngaphantsi kwe-19% kwandisa kakhulu i-pitting kunye nohlaselo lwe-intergranular. Kwii-alloys ze-nickel-chromium-iron ezisetyenziswa kwizityalo zeekhemikhali, ukulahleka kwe-chromium eyi-2% kunciphisa ubomi benkonzo ngama-40%, okukhokelela ekwandeni kokugcinwa kunye nokucima okungacwangciswanga.
Imingeni ephambili kuHlalutyo lweZinto eziSekwe kwiNickel
I-iron, i-nickel, kunye ne-chromium zine-fluorescence peaks ezidibanayo, nto leyo eyenza kube nzima ukulinganisa i-XRF okanye i-spectroscopic. Ii-matrices ze-multi-element ezine-trace molybdenum okanye i-niobium zifuna ukulinganiswa okuzinzileyo kunye nokuchaneka. Iimpazamo ezivela kwiziphumo ze-matrix okanye i-calibration drift zikhokelela ekuhleleni i-alloy ngendlela engalunganga, kwiingozi zokuthembeka, okanye ukwaphulwa kwezivumelwano zobugcisa, kunye namabango ewaranti kunye nokuvezwa koxanduva.
Indlela yokusebenzisa uHlalutyo lwe-XRF kwiZiko lakho
Ukulungiselela iSampulu kunye neMikhwa eBalaseleyo
Iindawo ezicocekileyo zesampulu zibalulekile; susa ioyile, ii-oxide, okanye iinxalenye. Iimilo ezithe tyaba nezifanayo ziphucula ukuchaneka, kodwa iLonnmeter XRF iyaziqhelanisa neemo ezingaqhelekanga.
Ukudibanisa i-XRF kwiMigqaliselo yoQinisekiso loMgangatho

Idatha yohlalutyo ingathunyelwa ngaphandle ukuze kulandelelwe kwaye kuthotyelwe uphicotho.
Imibuzo ebuzwa rhoqo
Zithini ii-alloys ezisekelwe kwi-nickel kwaye kutheni zibalulekile?
Ii-alloy ezisekelwe kwi-nickel zizinto zesinyithi ezine-nickel njengeyona nto iphambili, edla ngokuxutywa nentsimbi kunye ne-chromium. Ezi alloy zibonisa amandla abalaseleyo obushushu obuphezulu, ukumelana nokugqwala, kunye nozinzo kwiindawo zokusebenza ezinobundlongondlongo.
Kutheni umxholo we-chromium ubalulekile kwii-alloys ezisekelwe kwi-nickel?
I-Chromium yenza ngokuzenzekelayo umaleko we-Cr₂O₃ passivation kwiindawo ze-alloy ezingaphezulu kwe-12% yomxholo. Ii-alloys ezine-19–23% ye-chromium zibonisa ukhuseleko oluphezulu, zithintela ukusasazeka kwe-oxygen kunye ne-halides ngaphakathi.
