Blueing

Bluing simbi - zvemakemikari muitiro kushandiswa kugadzirira pemvura esimbi zvikamu mutete inodzivirira firimu pakati oxides Fe3O4 simbi. The zita anowana kubva maitiro ruvara zvikamu pashure processing (rinokwanisa kucheneruka-dema, namarudzi), hunonziwo "blackening" kana "sinenie" zvavo, pasinei noruvara - "oxidation". The zvichiguma firimu passivates pemvura uye kudzivirira chikamu kubva mumhepo ngura uye zvimwe zvinokonzerwa kungatikanganisa vezvenhau.

Usati burnishing simbi yksityiskohta kare kugadzirira, anatswa ngura mechanically yakakweshwa, degreased uye pickled zvine acidic mhinduro. Degreasing zvinogona solvent kana doro. Etching vanofanira kubvisa pachiso zvose zvisingakoshi oxides, vachisiya pachena simbi.

Nyore nzira - burnishing mafuta simbi. Pane nzira dzakasiyana, asi zvazvinoreva nyore: asi workpiece, nhete rukoko ramafuta, ipapo anofanira neshungu kuti 300-350 ° C. Ruomba, yakagochwa kuburikidza, anosiya pamusoro pechiso oxide firimu. Kubva panguva yokutanga yunifomu unhani haina kuwana, saka muitiro inodzokororwa kusvikira zvinodiwa mugumisiro. Zvakakosha kuwana yunifomu kudziyisa, zvikasadaro firimu vachaenda mavara, uye regai overheat zvikamu, sezvo zvingaita deform kana kusunungurwa. vanhu vakawanda vachiita chikanganiso uye osiyana chinhu ari mafuta preheated, hazvina kunaka. Zvinofanira kuva chaizvo wakatarisana: kutanga, vaname, ipapo achidziya. Oil kushandisa, kubva sunflower nokupfuuridzirwa kana injini. bluing simbi kwakadaro ane pasi unhani simba. Zviri chete kushanda muna decoration uye anodzivirira zvinangwa.

Bluing simbi achishandisa simbi sulphate, ferric chloride uye nitric asidhi

Nokuti chinangwa ichi, paminiti fő mvura vaifanira kukurumidza 15 g simbi sulphate uye 30 g 10 g acid. The chigadzirwa iri akatura kupinda mhinduro chichagadzirirwa ruosteessa unhani, zvakakodzera nguva kubvisa bhurasho uye Dip mberi kusvikira zvinodiwa Ruvara oxide firimu. Zvino guta rose rinenge pane amatura anotengesa mishonga, saka kuti kwavari zviri nyore.

Bluing simbi kushandisa potassium bichromate (potassium dichromate). Nokuti chinangwa ichi, paminiti fő kwemvura rakasanganiswa 200 magiramu kuti potassium bichromate uye akabhabhatidzwa muna mhinduro kwemaminitsi 20-30 chinhu. Mushure kubviswa kubva mhinduro uye ingapwa panguva mukuru tembiricha (muchoto kana pamusoro pamazimbe). The kwacho inodzokororwa kusvikira yebhuruu-dema yunifomu ruvara. Zvadaro pukuta achangodya chinamafuta jira. Chrompick - reagent kwakajairika chaizvo, rinoshandiswa mune nedehwe indasitiri.

Nokuti bluing nepfuti emiti yakasananiswa pasi kudziyisa 1 chikamu maererano nokurema namavara akanaka trichloride pamwe 3 zvikamu mafuta. Musanganiswa akabva kureva chinhu uye kubvumirwa kumira kuti zuva. The kwacho inodzokororwa 10-12 nguva, pashure iyo dhiramu yasukwa, yaoma uye rinobwinya. Ruvara greenish mashava.

Sezvinoonekwa kubva apa, burnishing simbi kumba - zvikuru noitika uye nyore muitiro. Inogona kushandawo kune zvivezwa zvakagadzirwa simbi mune zviitiko apo dzimwe nzira ngura nedziviriro, akadai pendi, havasi zvinoshanda.
