INCONEL 625, Ingxubevange 625

N06625 tubing, Ingxubevange 625 amapuleti

I-INCONEL nickel-chromium 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). Ukwakheka kukhonjisiwe kuThebula elingezansi.

Amandla e-INCONEL 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-INCONEL 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 okuqinile, kanye nokumelana nokuqhekeka kwe-chloride-ion stress-corrosion. Isetshenziswa njengentambo yocingo yokubopha izintambo, izinsimbi zophephela ezikebheni ezihamba ngaphansi kolwandle, izinjini ezisiza umkhumbi-ngwenya, izixhumo zokunqamula ngokushesha, imigudu yokukhipha umoya ezikebheni ezisetshenziswa yiNavy, kanye nokushelela izintambo zokuxhumana ngaphansi kolwandle, izilawuli ezishintshashintshayo ezihamba ngaphansi kolwandle, kanye nezivunguvungu zentambo yomusi. . Izinhlelo ezingase zisetshenziselwe iziphethu, ama-seal, izivunguvungu zezilawuli ezingaphansi kwamanzi, izixhumi zamakhebula kagesi, izixhumi, amadivaysi e-flexure, nezingxenye zethuluzi le-oceanographic.

Ukuqina okuphezulu, ukukhasa, kanye namandla okuphuka; ukukhathala okuvelele namandla okushisa-ukukhathala; ukumelana ne-oxidation; kanye nekhono elihle kakhulu lokushisela kanye nekhono le-braze yizici ze-INCONEL alloy 625 ezenza ithakaseleke emkhakheni we-aerospace. Isetshenziswa ezintweni ezinjengamasistimu okudonsa indiza, amasistimu e-exhaust yenjini, ama-thrust-reverser, izakhiwo zekhekheba lezinyosi ezikwazi ukumelana nokulawula injini yezindlu, uphethiloli kanye namashubhu olayini osebenza ngogesi, izinsimbi zokufutha, izivunguvungu, izindandatho zendwangu yomshini wokushisa, namashubhu okushintshanisa ukushisa. ezinhlelweni zokulawula imvelo. Ilungele futhi amalayini okushintsha amasistimu omlilo, ama-turbine seal, ama-compressor vanes, kanye namashubhu e-thrust-chamber amarokhethi.

Ukumelana nokugqwala okuvelele nokuguquguqukayo kwe-INCONEL alloy 625 ngaphansi kwebanga elibanzi lokushisa nezingcindezi kuyisizathu esiyinhloko sokwamukelwa kwayo okubanzi emkhakheni wokucubungula amakhemikhali. Ngenxa yokulula kwayo ukwenza, yenziwa izingxenye ezihlukahlukene zemishini yezitshalo. Amandla ayo aphezulu enza ukuthi isetshenziswe, isibonelo, emikhunjini enezindonga ezincane noma amashubhu kunokuba kungenzeka ngezinye izinto, ngaleyo ndlela kuthuthukiswe ukudluliswa kokushisa nokulondoloza isisindo. Ezinye izinhlelo zokusebenza ezidinga inhlanganisela yamandla nokumelana nokugqwala okunikezwa yi-INCONEL alloy 625 amakepisi amabhamuza, amashubhu, imikhumbi yokusabela, amakholomu okukhipha isisu, izishintshisi zokushisa, amapayipi okudlulisa, namavalvu.

Emkhakheni we-nuclear, i-INCONEL alloy 625 ingase isetshenziselwe izingxenye ze-reactor-core kanye ne-control-rod kuma-reactors amanzi enuzi. Impahla ingakhethwa ngenxa yamandla ayo aphezulu, ukumelana okuhle kakhulu kokugqwala okufanayo, ukumelana nokuqhekeka kwengcindezi nokumelana nokugoba okuhle kakhulu ku-500 ° -600 ° F (260-316 ° C) emanzini. I-alloy 625 nayo iyacatshangelwa emicabangweni ye-reactor ethuthukisiwe ngenxa yamandla ayo okuklama aphezulu avunyelwe emazingeni okushisa aphakeme, ikakhulukazi phakathi kuka-1200°-1400°F (649-760°C).

Izakhiwo ezinikezwe kulo mbiko, imiphumela yokuhlolwa okubanzi, zifana nengxubevange kodwa akufanele zisetshenziselwe izinjongo zokucaciswa. Ukucaciswa okusebenzayo kuvela esigabeni sokugcina salokhu kushicilelwa.
