Isingeniso Ekuhlukanisweni Kwama-Alloys Asekelwe Ku-Nickel
Ama-alloy asekelwe ku-nickel ayiqembu lezinto ezihlanganisa i-nickel nezinye izinto ezifana ne-chromium, i-iron, i-cobalt, ne-molybdenum, phakathi kwezinye. Asetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yezakhiwo zawo ezinhle kakhulu zemishini, ukumelana nokugqwala, kanye nokusebenza kahle kwezinga lokushisa eliphezulu.
Ukuhlukaniswa kwama-alloy asekelwe ku-nickel kusekelwe ekwakhiweni kwawo, izakhiwo zawo, kanye nokusetshenziswa kwawo. Nazi ezinye zezinhlobo ezivame kakhulu:
I-Monel iyiqembu lama-alloy e-nickel-copper aziwa kakhulu ngokumelana kwawo nokugqwala kanye namandla okushisa aphezulu. I-Monel 400, isibonelo, iyi-alloy esetshenziswa kabanzi ekusetshenzisweni kwasolwandle ngenxa yokumelana kwayo nokugqwala kwamanzi olwandle.
I-Inconel umndeni wama-alloy akhiwe ngokuyinhloko yi-nickel, i-chromium, ne-iron. Ama-alloy e-Inconel anikeza ukumelana okuhle kakhulu ezindaweni ezishisa kakhulu futhi asetshenziswa kabanzi embonini yezindiza kanye nokucubungula amakhemikhali.
I-Hastelloy iyiqembu lama-alloy e-nickel-molybdenum-chromium amelana kakhulu nokugqwala ezindaweni eziningi ezahlukene, kufaka phakathi ama-acid, izisekelo, namanzi olwandle. Ama-alloy e-Hastelloy avame ukusetshenziswa ekucubungulweni kwamakhemikhali kanye nasekukhiqizweni kwe-pulp nephepha.
I-Waspaloy iyi-superalloy esekelwe ku-nickel enikeza amandla amahle kakhulu okushisa okuphezulu kanye nokumelana nokugqwala. Ivame ukusetshenziswa ezingxenyeni zenjini yezindiza nakwezinye izinhlelo zokusebenza ezicindezela kakhulu.
Ama-alloy e-Rene ayiqembu lama-superalloy asekelwe ku-nickel aziwa ngamandla awo okushisa okuphezulu kanye nokumelana nokukhukhuleka. Avame ukusetshenziswa ezisetshenziswayo zezindiza njengezinsimbi ze-turbine kanye nezinhlelo zokukhipha umoya ezishisa kakhulu.
Ekuphetheni, ama-alloy asekelwe ku-nickel awumndeni wezinto eziguquguqukayo ezibonisa izakhiwo ezihlukile zemishini kanye nokumelana nokugqwala. Ukukhetha ukuthi iyiphi i-alloy ozoyisebenzisa kuzoncika ekusetshenzisweni okuthile kanye nezakhiwo zemishini namakhemikhali ezidingekayo.
