Gukata ibyuma

1. Ibikoresho byo gushakisha

. Ibisanzwe bikoreshwa mu muringa zinc brazing kuzuza ibyuma ni b-cu62znnimusir, b-cu60zusnr na b-cu58znfer. Imbaraga zingirakamaro zicyuma gishyizwe hamwe muri rusange zigera kuri 120 ~ 150MPa. Hishimikijwe umuringa wa zinc brazing wuzuza ibyuma, Mn, Ni, Sn, AI nibindi bintu byongeweho kugirango urugingo rusobekeranye rufite imbaraga zimwe nicyuma fatizo.

Ubushyuhe bwo gushonga bwa feza y'umuringa wuzuza ibyuma ni bike. Imiterere yangiza irashobora kwirindwa mugihe ucyuye ibyuma. Igice cya brazing gifite imikorere myiza, cyane cyane icyuma cyuzuza icyuma kirimo Ni, nka b-ag50cuzncdni na b-ag40cuznsnni, byongera imbaraga zo guhuza ibyuma byuzuza ibyuma hamwe nicyuma. Birakwiriye cyane cyane gusya ibyuma bya nodular bikozwe mu cyuma, bishobora gutuma urugingo rugira imbaraga zimwe nicyuma fatizo.

. Mubyongeyeho, flux igizwe na h3bo340%, li2co316%, na2co324%, naf7.4% na nac112,6% nibyiza.

Mugihe cyo gutekesha ibyuma hamwe nicyuma cyumuringa wuzuza ibyuma, fluxes nka fb101 na fb102 zirashobora gutoranywa, ni ukuvuga imvange ya borax, aside boric, fluoride potasiyumu na fluoroborate ya potasiyumu.

2. Gukoresha tekinoroji

Mbere yo gukata ibyuma, grafite, oxyde, umucanga, irangi ryamavuta hamwe nizindi sundry hejuru yubutaka bigomba gukurwaho neza. Gukoresha ibishishwa bya elegitoronike birashobora gukoreshwa mugukuraho amavuta, mugihe uburyo bwubukanishi nko guturika umucanga cyangwa guturika ibisasu, cyangwa uburyo bwa electrochemicique burashobora gukoreshwa mugukuraho grafite na okiside. Byongeye kandi, grafite irashobora gukurwaho no kuyitwika n'umuriro wa okiside.

Gukata ibyuma birashobora gushyukwa numuriro, itanura cyangwa induction. Kubera ko SiO2 yoroshye gukora hejuru yicyuma, ingaruka zo gutwika ikirere kirinda ntabwo ari nziza. Mubisanzwe, brazing flux ikoreshwa mugukata. Iyo usya ibihangano binini hamwe n'umuringa wa zinc ukonjesha icyuma cyuzuza, hagomba kubanza guterwa igice cyogejwe hejuru y’isuku, hanyuma ibihangano bigashyirwa mu itanura kugirango bishyushye cyangwa bishyushye hamwe n’itara ryo gusudira. Iyo igicapo gishyushye kigera kuri 800 ℃, ongeramo flux yinyongera, shyushya ubushyuhe bukabije, hanyuma usibe ibikoresho bya inshinge kumpera yumutwe kugirango ushongeshe uwagurishije hanyuma wuzuze icyuho. Kugirango hongerwe imbaraga imbaraga zifatanije, kuvura annealing bizakorwa kuri 700 ~ 750 ℃ ​​kuri 20min nyuma yo gushiramo, hanyuma hakorwe ubukonje buhoro.

Nyuma yo gushakisha, flux irenze nibisigara birashobora gukurwaho no koza amazi ashyushye. Niba bigoye kuyikuramo, irashobora gusukurwa hamwe na 10% ya acide sulfurike ya acide cyangwa 5% ~ 10% ya acide ya fosifori, hanyuma igasukurwa namazi meza.
