Ibyuma by'agaciro byerekeza cyane cyane kuri Au, Ag, PD, Pt nibindi bikoresho, bifite imiyoboro myiza, ubushyuhe bwumuriro, kurwanya ruswa hamwe nubushyuhe bwo hejuru.Zikoreshwa cyane mubikoresho byamashanyarazi mugukora ibice byumuzingi bifunze kandi bifunze.
. ibiranga ibikoresho byitumanaho nibikoresho byamashanyarazi yibigize.Kubera ko aho abantu bahurira ari ntarengwa, kugurisha birenze ntibyemewe, kandi ibipimo byo gushakisha bigomba kugenzurwa cyane.
Uburyo bwinshi bwo gushyushya burashobora gukoreshwa mugukata ibyuma byagaciro hamwe nibyuma byabigenewe.Flame brazing ikoreshwa kenshi mubice binini byo guhuza;Induction brazing irakwiriye kubyara umusaruro.Kurwanya inzitizi birashobora gukorwa hamwe nimashini isanzwe yo gusudira, ariko hagomba gutoranywa igihe gito nigihe kirekire cyo gushakisha.Guhagarika karubone birashobora gukoreshwa nka electrode.Mugihe bibaye ngombwa guhagarika umubare munini wibice byitumanaho icyarimwe cyangwa ugahuza imibonano myinshi kumurongo umwe, gutwika itanura birashobora gukoreshwa.Iyo ibyuma byiza byashizwemo nuburyo busanzwe mukirere, ubwiza bwingingo buba bubi, mugihe gukata vacuum bishobora kubona ingingo zujuje ubuziranenge, kandi imiterere yibikoresho ubwabyo ntibizagira ingaruka.
.Ifeza ishingiye ku muringa hamwe n’umuringa wuzuza ibyuma bikoreshwa cyane cyane muguhuza, ntabwo byemeza gusa ubworoherane bwikomatanya, ariko kandi biroroshye.Niba ibisabwa byujuje ubuziranenge bishobora kuzuzwa, ibyuma byuzuza ibyuma birimo Ni, PD, Pt nibindi bintu birashobora gukoreshwa, kandi ibyuma byuzuza ibyuma hamwe na nikel ya brazing, diyama ya diyama hamwe no kurwanya okiside nziza nabyo birashobora gukoreshwa.Niba Ag Cu Ti brazing yuzuza icyuma cyatoranijwe, ubushyuhe bwa brazing ntibushobora kuba hejuru ya 1000 ℃
Okiside ya feza ikozwe hejuru yifeza ntabwo ihagaze neza kandi byoroshye kuyishakisha.Kugurisha ifeza birashobora gukoresha amabati yuzuza ibyuma hamwe na zinc chloride yumuti wamazi cyangwa rosin nka flux.Iyo gukata, ibyuma byuzuza feza bikunze gukoreshwa, na borax, aside boric cyangwa imvange yabyo ikoreshwa nka brazing flux.Iyo vacuum ifata ifeza na feza ivanze, ifeza ishingiye kumuringa wuzuza ibyuma ikoreshwa cyane cyane nka b-ag61culn, b-ag59cu5n, b-ag72cu, nibindi.
Kubireba palladium ihuza, zahabu ishingiye hamwe na nikel igurisha byoroshye gukora ibisubizo bikomeye, cyangwa ifeza ishingiye kumuringa, umuringa ushingiye cyangwa manganese igurisha irashobora gukoreshwa.Ifeza fatizo ikoreshwa cyane mugushakisha platine na platine ivanze.Umuringa ushingiye, zahabu ishingiye cyangwa palladium ugurisha.Guhitamo b-an70pt30 gushakisha ibyuma byuzuza ntibishobora gusa guhindura ibara rya platine, ahubwo birashobora no kuzamura neza ubushyuhe bwo guhinduranya ubushyuhe bwo gufatana hamwe no kongera imbaraga nubukomezi bwo gufatana hamwe.Niba umubonano wa platine ugomba gutondekwa neza kuri kovar alloy, b-ti49cu49be2 ugurisha arashobora gutoranywa.Kubijyanye na platine hamwe nubushyuhe bwakazi butarenga 400 ℃ muburyo butangirika, ogisijeni yubusa yumuringa ugurisha hamwe nigiciro gito kandi imikorere myiza igomba guhitamo.
(3) Mbere yo gushakisha, gusudira, cyane cyane inteko ihuza, bigomba kugenzurwa.Guhuza gukubiswe ku isahani yoroheje cyangwa gukata kumurongo ntibishobora guhinduka kubera gukubita no gukata.Ubuso bwa brazing yubusabane bwakozwe no kubabaza, gukanda neza no guhimba bigomba kuba bigororotse kugirango habeho imikoranire myiza nubuso buringaniye bwinkunga.Ubuso bugoramye bwigice cyo gusudwa cyangwa hejuru ya radiyo iyo ari yo yose bigomba kuba bihamye kugirango habeho ingaruka nziza ya capillary mugihe cyo gushakisha.
Mbere yo gushakisha amakuru atandukanye, firime ya oxyde hejuru yubudodo igomba gukurwaho hakoreshejwe uburyo bwa shimi cyangwa ubukanishi, kandi ubuso bwo gusudira bugomba guhanagurwa neza na lisansi cyangwa inzoga kugirango bikureho amavuta, amavuta, umukungugu numwanda bibuza gutose. no gutemba.
Ku gusudira duto, ibifatika bizakoreshwa mbere yo guhagarara kugirango harebwe niba bitazahinduka mugihe cyo gutunganya itanura no kuzuza ibyuma byuzuza, kandi ibiti byakoreshejwe ntibishobora kwangiza brazing.Kubisudira binini cyangwa guhuza bidasanzwe, guterana no guhagarara bigomba kuba binyuze muburyo bwa shobuja cyangwa igikoni kugirango gusudira muburyo butajegajega.
Bitewe nubushyuhe bwiza bwibikoresho byicyuma, igipimo cyo gushyuha kigomba kugenwa ukurikije ubwoko bwibikoresho.Mugihe cyo gukonjesha, igipimo kigomba kugenzurwa neza kugirango impagarara zifatika zifatanye;Uburyo bwo gushyushya bugomba gutuma ibice byasudutse bigera ku bushyuhe bwumuriro icyarimwe.Kubintu bito by'agaciro bihuza, ubushyuhe butaziguye bugomba kwirindwa kandi ibindi bice birashobora gukoreshwa mubushuhe.Umuvuduko runaka ugomba gukoreshwa kubitumanaho kugirango itumanaho rihamye mugihe ugurisha ashonga kandi atemba.Kugirango ugumane ubukana bwinkunga cyangwa inkunga, twirinda annealing.Ubushuhe burashobora kugarukira gusa hejuru yubuso, nko guhindura umwanya mugihe cyo gutwika umuriro, gushiramo induction cyangwa kurwanira kurwanya.Byongeye kandi, mu rwego rwo gukumira uwagurishije gushonga ibyuma byagaciro, ingamba nko kugenzura ingano y’umugurisha, kwirinda gushyuha cyane, kugabanya igihe cyo gutwika ku bushyuhe bukabije, no gutuma ubushyuhe bukwirakwizwa buringaniye burashobora gufatwa.
