I-alloy 625 amashubhu ahlanganisiwe

I-alloy 625 (UNS N06625/W.Nr. 2.4856) isetshenziselwa amandla ayo aphezulu, ukwakheka okuhle kakhulu (okubandakanya ukujoyina), kanye nokumelana nokugqwala okuvelele.Amazinga okushisa esevisi asukela ku-cryogenic kuya ku-1800°F (982°C).Amandla e-alloy 625 asuselwa kumphumela wokuqina we-molybdenum ne-niobium ku-matrix yayo ye-nickel-chromium;ngakho-ke imithi yokuqinisa imvula ayidingeki.Le nhlanganisela yezakhi iphinde ibe nesibopho sokumelana okuphakeme nenhlobonhlobo yezindawo ezibolayo ezinobunzima obungavamile kanye nemiphumela yokushisa ephezulu efana ne-oxidation kanye ne-carburization.Izakhiwo ze-alloy 625 ezikwenza kube ukukhetha okuhle kakhulu ekusetshenzisweni kwamanzi olwandle ukukhululeka ekuhlaselweni kwendawo (i-pitting kanye ne-crevice corrosion), amandla aphezulu okugqwala-ukukhathala, amandla aphezulu okuqina, kanye nokumelana nokuqhekeka kwe-chloride-ion stress-corrosion.Isetshenziswa njengentambo yocingo yezintambo zokubophela, izinsimbi zophephela ezikebheni ezigada izimoto, izinjini ezisiza umkhumbi-ngwenya, izixhumi zokunqamula ngokushesha, imigudu yokukhipha umoya ezikebheni zeNavy, izintambo zokuxhumana ngaphansi kolwandle, izilawuli ezishintshashintshayo ezihamba ngaphansi kolwandle, kanye nezivunguvungu zolayini.Izinhlelo ezingase zisetshenziswe iziphethu, ama-seal, izivunguvungu zezilawuli ezingaphansi kwamanzi, izixhumi zamakhebula kagesi, izixhumi, amadivaysi e-flexure, nezingxenye zamathuluzi e-oceanographic.Ukuqina okuphezulu, ukukhasa, kanye namandla okuphuka;ukukhathala okuvelele namandla okushisa-ukukhathala;ukumelana ne-oxidation;kanye nokushisela okuhle kakhulu kanye ne-brazeability yizici ze-alloy 625 ezenza kuthakazelise emkhakheni we-aerospace.Isetshenziswa ezinhlelweni ezinjengamasistimu okudonsa indiza, amasistimu e-exhaust yenjini, ama-thrust-reverser, izakhiwo zekhekheba lezinyosi ezishibhile zokulawula injini yezindlu, uphethiloli kanye namashubhu olayini osebenza ngogesi, imigoqo yokufafaza, izivunguvungu, izindandatho ze-turbine shroud, namashubhu okushintsha ukushisa ngaphakathi. izinhlelo zokulawula imvelo.Ilungele futhi amalayini okushintsha amasistimu omlilo, ama-turbine seal, ama-compressor vanes, namashubhu e-thrust-chamber for rocket.

IZICI

Ingxubevange 625 inamandla amahle kakhulu emazingeni okushisa afinyelela ku-816 ℃.Emazingeni okushisa aphakeme, amandla ayo ngokuvamile aphansi kunalawo amanye ama-alloys aqinisiwe esixazululo esiqinile.Ingxubevange 625 inokumelana okuhle kwe-oxidation emazingeni okushisa afinyelela ku-980 ℃ futhi ikhombisa ukumelana kahle nokugqwala okune-aqueous, kodwa imaphakathi uma iqhathaniswa namanye ama-alloy akwazi ukumelana nokugqwala.

IZICELO

Imboni yenqubo yamakhemikhali kanye nokusetshenziswa kwamanzi olwandle.I-alloy 625 isetshenziswa esikhathini esifushane emazingeni okushisa afinyelela ku-816 ℃.Ensizakalweni yesikhathi eside, ikhawulelwe kubukhulu obungu-593C, ngoba ukuchayeka isikhathi eside ngaphezu kuka-593℃ kuzoholela ekubambeni okukhulu.
