Ma alloy opangidwa ndi nickel ndi zitsulo zopangidwa ndi nickel zomwe zimakhala ndi nickel ngati chinthu chachikulu, nthawi zambiri zimaposa 50% kulemera kwake. Kapangidwe kake kakang'ono kamapangitsa mphamvu yamakina yapadera, kukana kugwedezeka, komanso kukhazikika kwa okosijeni mpaka 800°C. Zinthu izi zimapangitsa kuti ma alloy opangidwa ndi nickel akhale ofunikira mu injini za jet, ma turbine a gasi, malo opangira mphamvu za nyukiliya, ndi ma reactor a mankhwala komwe kuli kutentha kwambiri ndi malo owononga. Mumlengalenga, ma superalloy monga Inconel ndi Nimonic amapereka kukana kutopa panthawi yothamanga kwambiri. Pakukonza mankhwala, ma alloy amasunga magwiridwe antchito m'malo okhala ndi acidic yambiri kapena chlorine.

Udindo wa Zinthu Zopangira Alloying: Iron, Nickel, Chromium, ndi Beyond
Zowonjezera zinthu zimakhudza mwachindunji magwiridwe antchito a zinthu komanso kukana dzimbiri. Kuchuluka kwa chromium kuyambira 19% mpaka 23% kumathandiza kupanga wosanjikiza woteteza wa oxide, womwe umawonjezera kukana kwa zinthu zowononga komanso umawonjezera moyo wautali mu chitsulo chosapanga dzimbiri ndi ma superalloys. Nickel imalimbitsa kapangidwe ka kristalo ndikuwonjezera kukana kutentha, makamaka mumakina a aloyi achitsulo-nickel-chromium. Kuwonjezera kwa molybdenum, pamlingo wofika 9%, kumawonjezera kukana kwa dzimbiri la dzenje ndi ming'alu yomwe imapezeka m'madzi a m'nyanja komanso m'malo okhala ndi mankhwala oopsa. Iron imathandizira kukhazikika kwa makina kudzera mu kulimbitsa yankho ndipo imapereka ndalama zogwirira ntchito m'magiredi ambiri.
Kufunika kwa Kutsimikiza Kulondola kwa Zinthu Zoyambira
Kugwira Ntchito, Kutsatira Malamulo, ndi Kukhala ndi Moyo Wautali
Deta yolondola ya kapangidwe ka zinthu za elementi imaonetsetsa kuti zinthu zopangidwa ndi nickel zikugwirizana ndi miyezo yamakina ndi chitetezo mumlengalenga ndi kupanga magetsi. Chiŵerengero cha chitsulo, nickel, ndi chromium cholamulidwa bwino (monga, 60–75% Ni, 19–23% Cr) chimakhudza mwachindunji mphamvu yokoka ndi kukana kukwera pa 700–1100°C. Kusanthula kolakwika kungayambitse ming'alu yosayembekezereka, kutayika kwa umphumphu wa kutentha kwambiri, kapena kulephera kwa dzimbiri kwakukulu m'malo olumikizirana mwamphamvu. Kutsimikiza kwa khalidwe ndi kutsata kumadalira kutsimikizika kolondola kwa elementi kuti zitsatire malamulo ndi chitsimikizo chotsimikizika.
Kuchuluka kwa Chromium ndi Kukana Kudzimbiri
Chromium pa 19–23% imapanga filimu yosalekeza ya Cr₂O₃ oxide, yofunika kwambiri polimbana ndi ma acid, ma caustics, ndi ma oxidation otentha kwambiri. Kukana dzimbiri kwa chitsulo chosapanga dzimbiri kumafuna chromium peresenti yochepa: pansi pa 19% kumawonjezera kwambiri kuukira kwa ma pitting ndi ma granular. Mu nickel-chromium-iron alloys zomwe zimagwiritsidwa ntchito m'mafakitale a mankhwala, kutayika kwa chromium 2% kumachepetsa moyo wa ntchito ndi 40%, zomwe zimapangitsa kuti pakhale kukonza kwakukulu komanso kuzima kwa madzi kosayembekezereka.
Mavuto Ofunika Kwambiri Pakusanthula Kwazinthu Zachilengedwe pa Ma Alloys Ochokera ku Nickel
Chitsulo, nickel, ndi chromium zili ndi ma fluorescence peaks ofanana, zomwe zimapangitsa kuti XRF kapena spectroscopic quantification zikhale zovuta. Ma multi-element matrices okhala ndi trace molybdenum kapena niobium amafuna stable calibration ndi precision. Zolakwika zochokera ku matrix effects kapena calibration drift zimapangitsa kuti alloy sorting isachitike bwino, chiopsezo cha umphumphu, kapena kuswa mapangano aukadaulo, ndi chitsimikizo cha chitsimikizo ndi kuwonekera kwa udindo.
Momwe Mungagwiritsire Ntchito Kusanthula kwa XRF mu Malo Anu
Kukonzekera Zitsanzo ndi Njira Zabwino Kwambiri
Malo oyera a zitsanzo ndi ofunikira; chotsani mafuta, ma oxide, kapena tinthu tating'onoting'ono. Mawonekedwe athyathyathya, ofanana amawongolera kulondola, koma Lonnmeter XRF imasintha kukhala mawonekedwe osakhazikika.
Kuphatikiza XRF mu Njira Zotsimikizira Ubwino
Gwiritsani ntchito XRF kuti mutsimikizire zinthu zonse, kuyang'anira zinthu zomwe zikubwera, komanso QC yotuluka. Tsatirani zotsatira zowunikira kuti muwonetsetse kuti zinthuzo zikugwirizana kuyambira pachiyambi mpaka kumapeto.
Kusamalira ndi Kutsata Deta
Sungani zolemba za muyeso pa digito kuti ziwunikidwe ndi malamulo komanso kuti zitsatidwe bwino. Tumizani zotsatira ku malo osungiramo zinthu kuti muyang'anire bwino zinthu.
Chowunikira cha Lonnmeter XRF chimalola kusanthula mwachangu zinthu zomwe zili mu alloy yolimba. Zotsatira za chitsulo, nickel, chromium, ndi molybdenum zimaperekedwa mumasekondi, ndipo chromium imachepa kufika pa 0.01%. Deta yowunikira imatha kutumizidwa kunja kuti itsatidwe komanso kutsatiridwa ndi ma audit.
Mafunso Ofunsidwa Kawirikawiri
Kodi ma alloys okhala ndi nickel ndi chiyani ndipo chifukwa chiyani ndi ofunikira?
Ma alloy okhala ndi nickel ndi zinthu zachitsulo zomwe nickel ndiye chinthu chachikulu chomwe chimagwiritsidwa ntchito, nthawi zambiri chimaphatikizidwa ndi chitsulo ndi chromium. Ma alloy amenewa amasonyeza mphamvu yapamwamba kwambiri kutentha, kukana dzimbiri, komanso kukhazikika m'malo ogwirira ntchito mwamphamvu.
Chifukwa chiyani kuchuluka kwa chromium ndikofunikira kwambiri mu ma alloys okhala ndi nickel?
Chromium imapanga Cr₂O₃ passivation layer pamwamba pa alloy pamwamba pa 12%. Alloys okhala ndi 19–23% chromium amakhala ndi chitetezo chapamwamba, choletsa kufalikira kwa mpweya ndi halides mkati.
