Ama-alloy asekelwe ku-nickel ayizinsimbi ezakhiwe eziqukethe i-nickel njengento eyinhloko, ngokuvamile edlula u-50% ngesisindo. Isakhiwo sawo esincane senza amandla akhethekile okusebenza, ukumelana nokuqhekeka, kanye nokuqina kwe-oxidation kufike ku-800°C. Lezi zakhiwo zenza ama-alloy asekelwe ku-nickel abaluleke kakhulu ezinjinini zejethi, kuma-turbine egesi, ezitshalweni zamandla enuzi, kanye nasezikhungweni zamakhemikhali lapho kukhona khona ukushisa okukhulu kanye nezindawo ezigqwalisayo. Ezindiza, ama-superalloy anjenge-Inconel ne-Nimonic anikeza ukumelana nokukhathala ngesikhathi sokujikeleza okusheshayo kokushisa. Ekucutshungulweni kwamakhemikhali, ama-alloy agcina ukusebenza kahle ezindaweni ezine-acid noma i-chlorine ephezulu.

Indima Yezinto Zokuhlanganisa: I-Iron, i-Nickel, i-Chromium, kanye Nangaphandle Kwayo
Izengezo zezinto eziyisisekelo zithinta ngqo ukusebenza kwezinto kanye nokumelana nokugqwala. Okuqukethwe kwe-chromium okusukela ku-19% kuya ku-23% kwenza ukwakheka kwengqimba ye-oxide evikelayo eqhubekayo, okwandisa kakhulu ukumelana nezinto ezigqwala futhi kuthuthukise isikhathi eside ensimbi engagqwali kanye nama-superalloy. I-Nickel izinzisa isakhiwo sekristalu futhi ikhulisa ukumelana nokushisa, ikakhulukazi ezinhlelweni ze-iron-nickel-chromium alloy. Ukwengezwa kwe-molybdenum, emazingeni afinyelela ku-9%, kwandisa kakhulu ukumelana nokugqwala kwemigodi kanye nemifantu okuvamile emanzini olwandle nasezindaweni zamakhemikhali ezinolaka. I-iron inikela ekuzinzeni kwemishini ngokuqinisa isixazululo futhi inikeza ukusebenza kahle kwezindleko emabangeni amaningi.
Ukubaluleka Kokunqunywa Kokwakheka Okunembile Kwezinto Eziyisisekelo
Ukusebenza, Ukuthobela, kanye Nokuphila Isikhathi Eside
Idatha enembile yokwakheka kwezinto eziyisisekelo iqinisekisa ukuthi ama-alloy asekelwe ku-nickel ahlangabezana nezindinganiso zokuphepha kwezindiza kanye nokukhiqizwa kwamandla. Izilinganiso zensimbi, i-nickel, kanye ne-chromium ezilawulwa ngokuqinile (isb., 60–75% Ni, 19–23% Cr) zithinta ngqo amandla okudonseka kanye nokumelana nokuqhekeka ku-700–1100°C. Ukuhlaziywa okungalungile kungabangela ukuqhekeka okungalindelekile, ukulahlekelwa ubuqotho bokushisa okuphezulu, noma ukwehluleka okukhulu kokugqwala ezindaweni ezihlaselayo. Ukuqinisekiswa kwekhwalithi kanye nokulandelela kuncike ekuqinisekisweni okunembile kwezinto eziyisisekelo ukuze kulandelwe imithetho kanye nokuqinisekiswa kwewaranti.
Okuqukethwe kwe-Chromium kanye nokumelana nokugqwala
I-Chromium ku-19–23% yakha ifilimu ye-Cr₂O₃ oxide eqhubekayo, ebalulekile ekumelaneni nama-acid, ama-caustics, kanye ne-oxidation yokushisa okuphezulu. Ukumelana nokugqwala kwensimbi engagqwali kudinga iphesenti elincane le-chromium: ngaphansi kuka-19% kwandisa kakhulu imigodi kanye nokuhlasela kwe-intergranular. Kuma-alloy e-nickel-chromium-iron asetshenziswa ezitshalweni zamakhemikhali, ukulahlekelwa yi-chromium engu-2% kunciphisa impilo yesevisi ngo-40%, okuholela ekunakekelweni okwandisiwe kanye nokungasebenzi kahle okungahleliwe.
Izinselele Eziyinhloko Ekuhlaziyweni Kwezinto Eziyisisekelo Zama-Alloys Asekelwe Ku-Nickel
I-iron, i-nickel, ne-chromium zineziqongo ze-fluorescence ezihambisanayo, okwenza kube nzima ukulinganisa i-XRF noma i-spectroscopic. Ama-matrices e-Multi-element ane-trace molybdenum noma i-niobium adinga ukulinganiswa okuzinzile kanye nokunemba. Amaphutha avela emiphumeleni ye-matrix noma ukukhukhuleka kokulinganisa aholela ekuhlungeni okungalungile kwe-alloy, izingozi zobuqotho, noma ukwephulwa kwezinkontileka zobuchwepheshe, ngezimangalo zewaranti kanye nokuvezwa kwesibopho.
Indlela Yokusebenzisa Ukuhlaziywa kwe-XRF Esikhungweni Sakho
Ukulungiselela Isampula kanye Nemikhuba Emihle Kakhulu
Izindawo ezihlanzekile zesampula zibalulekile; susa uwoyela, ama-oxide, noma izinhlayiya. Izimo ezisicaba nezifanayo zithuthukisa ukunemba, kodwa i-Lonnmeter XRF ivumelana nezimo ezingajwayelekile.
Ukuhlanganisa i-XRF Emigudwini Yomsebenzi Wokuqinisekisa Ikhwalithi
Sebenzisa i-XRF ukuqinisekisa i-batch ejwayelekile, ukuhlolwa okungenayo, kanye ne-QC ephumayo. Landelela imiphumela yokuhlaziya ukuqinisekisa ukuhambisana komkhiqizo kusukela ekuqaleni kuze kube sekupheleni.
Ukuphathwa Kwedatha Nokulandelela
Gcina amarekhodi okulinganisa ngedijithali ukuze kuhlolwe ngokomthetho kanye nokulandelela izinqubo. Thumela imiphumela kudathabheyisi yesikhungo ukuze kuphathwe ikhwalithi ephakathi.
I-Lonnmeter XRF analyzer ivumela ukuhlaziywa okusheshayo kwezinto eziyisisekelo kumasampula e-alloy aqinile. Imiphumela yensimbi, i-nickel, i-chromium, ne-molybdenum ilethwa ngemizuzwana, kanye nokuzwela kwe-chromium kwehle kufike ku-0.01%. Idatha yokuhlaziya ingathunyelwa kwamanye amazwe ukuze kulandelelwe futhi kulandelwe ukuhlaziywa.
Imibuzo Evame Ukubuzwa
Ziyini izinsimbi ezisekelwe ku-nickel futhi kungani zibalulekile?
Ama-alloy asekelwe ku-nickel ayizinto zensimbi ezine-nickel njengesakhi esiyinhloko, ngokuvamile ezixutshwe nensimbi ne-chromium. Lawa ma-alloy abonisa amandla aphezulu okushisa, ukumelana nokugqwala, kanye nokuqina ezindaweni zokusebenza ezinolaka.
Kungani okuqukethwe kwe-chromium kubalulekile kuma-alloy asekelwe ku-nickel?
I-Chromium yakha ngokuzenzekelayo ungqimba lwe-Cr₂O₃ lokudlula ezindaweni ze-alloy ezingaphezu kuka-12% okuqukethwe. Ama-alloy ane-chromium engu-19–23% abonisa ukuvikelwa okuphezulu, evimbela ukusabalala kwangaphakathi kwe-oxygen kanye ne-halides.
