15CrMoG umuvuduko ukabije wibyuma byujuje ubuziranenge
15CrMoG umuyoboro wibyuma nubwoko bwicyuma kidafite icyuma, kandi imikorere yacyo irarenze cyane iy'umuyoboro usanzwe udafite icyuma. Kuberako ubu bwoko bwicyuma burimo Cr nyinshi, kurwanya ubushyuhe bwayo bwinshi, kurwanya ubushyuhe buke no kurwanya ruswa ntishobora kugereranywa nindi miyoboro yicyuma idafite icyuma, bityo umuyoboro wa alloy ukoreshwa cyane muri peteroli, inganda zikora imiti, amashanyarazi, amashyiga nizindi nganda .
Ihame ryo kweza hydrogène kumuyoboro wibyuma 15CrMoG nuko iyo hydrogène igomba kwezwa yinjijwe muruhande rumwe rwumuyoboro wibyuma wa 15CrMoG kuri 300-500 ℃, hydrogène yamamajwe kurukuta rwumuyoboro wibyuma 15CrMoG. Bitewe no kubura electroni ebyiri murwego rwa 4D electron ya palladium, irashobora gukora imiti ihuza imiti idahwitse hamwe na hydrogène (reaction hagati ya palladium na hydrogène irahinduka). Mubikorwa bya palladium, hydrogène iion muri proton ifite radiyo ya 1.5 × 1015m, mugihe lattice ihoraho ya palladium ari 3.88 × 10-10m (kuri 20 ℃), irashobora kunyura mumiyoboro ya 15CrMoG. Mubikorwa bya palladium, proton ihuza na electron hanyuma igakora molekile ya hydrogène, igahunga kurundi ruhande rwumuyoboro wibyuma wa 15CrMoG. Ku buso bwa 15CrMoG ivanga ibyuma, gaze itagabanijwe ntishobora kunyura, bityo umuyoboro wibyuma wa 15CrMoG urashobora gukoreshwa kugirango ubone hydrogène ifite isuku nyinshi.
Nubwo palladium ifite uburyo budasanzwe bwo kwinjiza hydrogène, palladium yera ifite imiterere mibi yubukanishi, okiside yoroshye kubushyuhe bwo hejuru hamwe nubushyuhe buke bwa rerystallisation, byoroshye guhindura no gushiramo umuyoboro wibyuma 15CrMoG. Kubwibyo, palladium yera ntishobora gukoreshwa nka membrane permeability. Ongeramo umubare ukwiye wibintu bya IB na VIII muri palladium kugirango palladium ivanze birashobora kunoza imiterere ya palladium. 11. Umuyoboro wicyuma udafite icyerekezo cya kimwe cya kabiri cyimodoka (gb3088-82) nicyuma cyiza cya karubone cyubatswe cyiza kandi kivanze nicyuma gishyushye cyuma-cyuma kitagira icyuma cyo gukora ibinyabiziga igice cya axe hamwe no gutwara amazu ya axle. Muri palladium alloy, ifeza ihwanye na 20-30%, kandi ibikubiye mubindi bice (nka zahabu, nibindi) ntibiri munsi ya 5%.
① Imibare ibiri mugitangiriro cyicyiciro cyerekana ibyuma byerekana karubone yibyuma, bigaragazwa nkibihumbi bike byikigereranyo cya karubone, nka 40Cr.
②Ibintu nyamukuru bivanga mubyuma, usibye ibintu bya microalloyed yibintu, mubisanzwe bigaragarira mubice bike. Iyo impuzandengo y'ibicuruzwa bivanze bitarenze 1.5%, mubisanzwe gusa ikimenyetso cyibintu cyerekanwe murwego rwicyuma, ariko ibirimo ntabwo byashyizweho ikimenyetso. Ariko, niba byoroshye kwitiranya mubihe bidasanzwe, umubare "1" urashobora kandi gushyirwaho ikimenyetso nyuma yikimenyetso, nkibipimo byibyuma "12CrMoV" na "12Cr1MoV". Chromium yibiri mubyambere ni 0.4-0,6%, naho iyanyuma ni 0.9-1.2%, nibindi bice byose ni bimwe. Iyo impuzandengo y'ibintu bivanze ni ≥ 1.5%, ≥ 2.5%, ≥ 3.5% ... Ibirimo bizerekanwa nyuma yikimenyetso cyibintu, bishobora kugaragazwa nka 2, 3, 4 ... Ibikurikira, 18Cr2Ni4WA.
③Vanadium V, titanium Ti, aluminium Al, boron B, isi idasanzwe RE nibindi bintu bivangwa mubyuma ni ibintu bya microalloyed. Nubwo ibirimo biri hasi cyane, bigomba gukomeza gushyirwaho urwego rwicyuma. Kurugero, muri 20mnvb ibyuma. 0.07-0.12% kuri vanadium na 0.001-0.005% kuri boron.
④ Ibyuma byujuje ubuziranenge bigomba gushyirwaho "a" nyuma yicyiciro cyicyuma kugirango gitandukane nicyuma rusange cyiza.
⑤Kubyuma byubaka ibyuma kubwintego yihariye, urwego rwicyuma rubanzirizwa na (cyangwa umugereka) kugirango ugereranye ikimenyetso cyintego yicyuma. Kurugero, 30CrMnSi ibyuma byo kuzunguruka bigereranwa nka ml30crmnsi.
Umuyoboro wa Alloy hamwe n'umuyoboro udafite uburinganire bifite isano nibitandukaniro, kandi ntibishobora kwitiranywa. Umuyoboro wa Alloy ni ubwoko bw'umuyoboro udafite kashe. Nubwo idashobora kuvangwa, umuyoboro utagira kashe urimo umuyoboro wa alloy.
Umuyoboro wa Alloy usobanurwa nkumuyoboro wibyuma ukurikije ibikoresho (ni ukuvuga ibikoresho). Nkuko izina ribigaragaza, ni umuyoboro wakozwe mu mavuta; Umuyoboro udafite icyerekezo usobanurwa ukurikije uburyo bwo gukora umuyoboro wibyuma (seamless seam). Ibitandukanye n'umuyoboro udafite ikidodo ni umuyoboro udafite ikidodo, harimo umuyoboro usudutse ugororotse hamwe n'umuyoboro uzunguruka.
