Gutera ibyuma bikora

1. Ibikoresho byo gutwika

(1) Titanium n'ibyuma byayo by'ibanze ntibikunze gushyirwaho icyuma gikozwe mu buryo bworoshye. Ibyuma bikoreshwa mu gushushanya birimo cyane cyane icyuma gikozwe mu ifeza, icyuma gikozwe muri aluminiyumu, icyuma gikozwe muri titanium cyangwa icyuma gikozwe muri zirconium.

Solder ishingiye ku ifeza ikoreshwa cyane cyane ku bice bifite ubushyuhe buri munsi ya 540 ℃. Impande zikoresha solder ya feza nziza zifite imbaraga nke, zoroshye gucikamo ibice, kandi ntizirwanya ingese kandi ntizirwanya ogisijeni. Ubushyuhe bwo gukamura bwa solder ya Ag Cu ni buke ugereranyije n'ubwa feza, ariko ubushobozi bwo gukamura bugabanuka uko ingano ya Cu yiyongera. Solder ya Ag Cu irimo Li nke ishobora kongera ubushobozi bwo gukamura no guteranya hagati ya solder n'icyuma cy'ibanze. Solder ya Ag Li ifite imiterere yo gushonga ku rugero ruto kandi igabanuka cyane. Ikwiriye gukamura titanium na titanium alloys mu kirere kirinda. Ariko, icyuma gifunga kidakoresha umwuka kizahumanya itanura bitewe n'umwuka wa Li. Ag-5al- (0.5 ~ 1.0) Mn filler metal ni cyo cyuma gikunzwe cyane ku bice bya titanium bifite inkuta nto. Impande ifite ogisijeni nziza kandi irwanya ingese. Ingufu zo gukamura titanium na titanium alloy ...

Imbonerahamwe ya 12 Ibipimo by'imikorere yo gufunga hamwe n'imbaraga z'ingingo za titaniyumu na titaniyumu

Ubushyuhe bwo gufunga icyuma gikozwe muri aluminiyumu buri hasi, ibyo bikaba bitazatuma habaho impinduka mu gice cya titaniyumu alloy β, bigabanya ibisabwa mu guhitamo ibikoresho n'imiterere ya brazing. Imikoranire hagati y'icyuma gifunga icyuma n'icyuma cy'ibanze ni mike, kandi gushonga no gukwirakwira ntibigaragara, ariko imiterere y'icyuma gifunga icyuma ni myiza, kandi biroroshye kuzingira icyuma gifunga icyuma n'icyuma cy'ibanze, bityo ikaba ikwiriye cyane gukoreshwa mu gufunga radiator ya titaniyumu alloy, imiterere y'ubuki n'imiterere ya laminate.

Uduce duto tw’amashanyarazi dushingiye kuri titanium cyangwa titanium zirconium muri rusange tuba dufite Cu, Ni n’ibindi bintu, bishobora gukwirakwira vuba muri matrix no gukorana na titanium mu gihe cyo gucura, bigatuma matrix ihinduka no kurema urwego rworoshye. Kubwibyo, ubushyuhe bwo gucura n’igihe cyo gufata bigomba kugenzurwa cyane mu gihe cyo gucura, kandi ntibigomba gukoreshwa mu gucura inkuta nto uko bishoboka kose. B-ti48zr48be ni solder isanzwe ya Ti Zr. Ifite ubushobozi bwo kumena neza kuri titanium, kandi icyuma cyo hasi ntigikunda gukura mu gihe cyo gucura.

(2) Ibyuma byo gushyiramo ibyuma bikoreshwa mu gusya zirconium na aloi z'ibanze. Gusya zirconium na aloi z'ibanze ahanini birimo b-zr50ag50, b-zr76sn24, b-zr95be5, nibindi, bikoreshwa cyane mu gusya imiyoboro ya zirconium aloi y'ingufu za kirimbuzi.

(3) Uburyo bwo gukurura umwuka n'ikirere kirinda titanium, zirconium na alloys z'ibanze bishobora gutanga umusaruro ushimishije mu mwuka udafite umwuka n'umwuka utagira umwuka (helium na argon). Argon ifite ubuziranenge bwinshi igomba gukoreshwa mu gukurura umwuka urinda argon, kandi ikigero cy'ikime kigomba kuba -54 ℃ cyangwa munsi yayo. Uburyo bwihariye bwo gukurura umwuka burimo fluoride na chloride by'icyuma Na, K na Li bigomba gukoreshwa mu gukurura umuriro.

2. Ikoranabuhanga ryo gushushanya

Mbere yo gusukamo icyuma, ubuso bugomba gusukurwa neza, gukurwamo amavuta no gukuraho agapira ka ogisijeni. Agapira ka ogisijeni gakomeye kagomba gukurwaho hakoreshejwe uburyo bwa mekanike, uburyo bwo guturika umucanga cyangwa uburyo bwo koga umunyu ushongeshejwe. Agapira ka ogisijeni gashobora gukurwamo mu gisubizo kirimo aside nitrike ya 20% ~ 40% na aside hydrofluoric ya 2%.

Ti, Zr n'ibyuma byazo ntibyemewe gukora ku buso bw'ingingo n'umwuka mu gihe cyo gushyushya icyuma. Gushyushya icyuma bishobora gukorwa hifashishijwe umwuka uvamo umwuka cyangwa umwuka udafite umwuka. Gushyushya icyuma cyangwa gushyushya icyuma mu buryo bworoshye bishobora gukoreshwa. Gushyushya icyuma ni bwo buryo bwiza ku bice bito bingana, mu gihe gushyushya icyuma mu itanura bigira akamaro cyane ku bice binini kandi bigoye.

Ni Cr, W, Mo, Ta n'ibindi bikoresho bigomba gutoranywa nk'ibintu bishyushya Ti, Zr n'ibindi bikoresho byabyo. Ibikoresho bifite grafiti yagaragaye nk'ibintu bishyushya ntibigomba gukoreshwa mu kwirinda ihumana rya karuboni. Igikoresho cyo gushyushya kigomba gukorwa mu bikoresho bifite imbaraga nziza z'ubushyuhe bwinshi, ingano y'ubushyuhe bwa Ti cyangwa Zr, kandi imikorere yayo ikaba mike hakoreshejwe icyuma gishingiyeho.
