I-Inconel 600 Nickel-based Alloy The Supreme High{2}}Champion Resistant Temperature in Harsh Environments

I-Inconel 600, njenge-nickel yakudala-i-chromium{2}}i-iron-esekelwe kusixazululo esiqinile esiqiniswe{4}}ne-temperature alloy ephezulu, ibilokhu itholakala kusukela maphakathi-nonyaka wama-20. Ngenxa yokuqina kwayo okusezingeni eliphezulu{8}}kwezinga lokushisa okuvelele kanye nokumelana nokugqwala okuhle kakhulu, isiphenduke into esemqoka ebalulekile emikhakheni yezimboni esezingeni eliphezulu njenge-aerospace, amakhemikhali kaphethiloli, amandla enuzi, nogesi.

I-Inconel 600 (UNS N06600/W.Nr.2.4816) ingummeleli ojwayelekile we-nickel-i-chromium-i-iron-esekelwe kusixazululo esiqinile esiqiniswe{7}}ama-alloys aphezulu. Yasungulwa futhi yathengiswa yi-International Nickel Company (INCO) ngeminyaka yawo-1940s futhi inomlando wokusebenzisa iminyaka engaphezu kwengama-80. Njengenye yezinto zokuqala ezithuthukisiwe ze-nickel{12}ezisekelwe{13}}ezisezingeni eliphezulu, i-Inconel 600 yahlangabezana nesidingo esiphuthumayo somkhakha wezimboni sezinto ezimbili{15}}ezinamandla okushisa aphezulu kanye nokumelana nokugqwala ngaleso sikhathi, okwabeka isisekelo sokuthuthukiswa kwamasistimu esimanjemanje{16} okushisa aphezulu. Le alloy igcina indawo engenakubuyiseleka kwezinye izinhlelo zokusebenza eziningi-zezinga lokushisa{19}}ezimelana nezifo ngenxa yokusebenza kwayo okulinganiselwe kanye nezindleko ezimaphakathi. Ngisho nokuvela okuqhubekayo kwezinto ezintsha, isidingo saso sonyaka emhlabeni wonke siyaqhubeka nokubonisa inkambiso yokukhula ezinzile.

Inzuzo eyinhloko ye-Inconel 600 ilele ekuhlanganiseni kwayo okuyingqayizivele kokusebenza: ngakolunye uhlangothi, okuqukethwe kwe-nickel engu-72% kuyinikeza ukumelana okuhle kakhulu nokugqwala ngokunciphisa ama-ejenti; ngakolunye uhlangothi, okuqukethwe kwe-chromium kwe-14-17% kunikeza ukumelana okuhle kwe-oxidation nokumelana nokuqhekeka kwe-chloride yokucindezeleka kokugqwala. Lesi silinganiso sokwakheka esilinganiselwe senza ingxubevange isebenze kahle ezindaweni zokugqwala eziyinkimbinkimbi ezishintshana phakathi kwe-oxidation nokunciphisa, okuyenza ibe enye yezinto ezimbalwa zensimbi ezikwazi ukumelana negesi ye-chlorine eyomile nokugqwala kwe-hydrogen chloride, nezinga lokushisa elifinyelela ku-650℃. Ngesikhathi esifanayo, okuqukethwe kwe-iron 6-10% akunciphisi nje kuphela izindleko kodwa futhi kuthuthukisa ukusebenza kwe-alloy, okwenza kube lula ukwakheka okushisayo nokushisela.
