Thaum nws los txog rau kev kho mob hlau, ntau tus neeg tam sim ntawd xav txog electroplating thiab painting. Tab sis hauv kev tsim khoom, muaj ib txoj hauv kev pheej yig thiab kev kho ntau yam - blackening.
Tej zaum koj yuav tsis tau hnov lub npe, tab sis koj tau pom tseeb tias nws zoo li cas. Cov matte dub screws, ntxhua khaub ncaws, springs, thiab cov txheej tiv thaiv tsaus nti ntawm cov khoom siv tshuab feem ntau yog qhov tshwm sim ntawm blackening.
Yog li cas txog "blueing"? Qee tus xav tias lawv yog tib yam, thaum lwm tus hais tias lawv yog ob txoj kev sib txawv kiag li. Hnub no, peb yuav qhia meej qhov no.

Ib txoj cai, ob qhov kub thiab txias
Blackening thiab blueing, hauv qhov tseem ceeb, ua haujlwm ntawm tib txoj cai.
Ob leeg siv tus neeg sawv cev oxidizing los tsim ib txheej ntawm hlau (II, III) oxide (Fe₃O₄) ntawm cov hlau nto. Cov zaj duab xis no yog nyias nyias, tsuas yog hais txog 0.5 txog 2.5 micrometers. Qhov ntawd txhais li cas? Nws yog thinner dua ib -fiftieth lub thickness ntawm tib neeg cov plaub hau.
Cov tshuaj oxidizing siv zoo sib xws, xws li cov tshuaj muaj zog oxidizing zoo li sodium hydroxide, sodium nitrite, thiab trisodium phosphate. Yog li dab tsi yog qhov txawv? Nws yog qhov kub thiab txias.
Blackening yog ua nyob rau hauv ib tug aqueous tov ntawm oxidizing neeg sawv cev ntawm ib ncig ntawm 130 degree. Cov khoom yog immersed nyob rau hauv cov tshuaj no rau ib lub sij hawm ntawm lub sij hawm, thiab saum npoo tig dub tsaus.
Bluing, ntawm qhov tod tes, yuav tsum muaj qhov kub ntawm ib ncig ntawm 550 degree. Cov khoom yog immersed nyob rau hauv molten oxidizing agents los yog muab tso rau hauv ib tug siab -kub qhov chaw ib puag ncig. Tom qab kev kho mob, qhov chaw zoo li dub lossis xiav tsaus. Cov xim xiav ntawd - xim dub yog lub hauv paus ntawm lub npe "bluing."

Qhov twg zoo dua? Nws nyob ntawm daim ntawv thov.
Txij li thaum bluing muaj qhov kub thiab txias dua thiab suab ntau "advanced," peb puas tuaj yeem siv bluing ncaj qha?
Tsis yog kiag li. Ob txheej txheem muaj lawv cov kev siv; tus yuam sij yog tus nqi thiab daim ntawv thov scenario.
Blackening kev kho mob yog tsawg-nqi thiab siv tau zoo, haum rau huab hwm coj- tsim cov khoom lag luam zoo tib yam. Piv txwv li, cov fasteners feem ntau (ntsia hlau, bolts, ntxhua khaub ncaws), cov khoom siv tshuab zoo tib yam, cov cuab yeej, thiab lwm yam. Nws tsis muaj qhov yuav tsum tau ua rau kev tiv thaiv xeb thiab feem ntau yog siv rau hauv qhov chaw qhuav. Cov khoom uas tau ua kom dub feem ntau yuav tsum tau coated nrog cov roj los tiv thaiv - xeb kom ntev lawv lub neej kev pab. Yog tsis muaj roj, lub peev xwm tiv thaiv xeb yog qhov tsis muaj zog.
Kev kho Bluing yog kim dua vim qhov kub thiab txias dua thiab cov txheej txheem nyuaj dua. Txawm li cas los xij, nws tsim cov yeeb yaj kiab oxide denser nrog kev tiv thaiv xeb zoo dua. Yog li ntawd, nws yog feem ntau siv nyob rau hauv cov chaw uas muaj siab dua qhov yuav tsum tau, xws li precision instruments, optical khoom, thiab riam phom tsim. Xav txog nws: rab phom thiab phom phom loj - khoom siv uas xav tau kev tiv thaiv xeb thiab qhov tseeb ntawm qhov chaw nyob hauv qhov chaw nyuaj -bluing yog qhov kev xaiv tsim nyog heev.

Cov hlau sib txawv xav tau lub sijhawm sib txawv.
Lwm qhov nthuav dav: txawm tias nrog blackening lossis bluing, kev ua haujlwm ceev sib txawv rau cov hlau sib txawv.
High - carbon steel reacts sai thiab muaj lub sijhawm ua haujlwm luv dua. Tsawg- carbon steel thiab alloy steel yuav tsum tau siv sijhawm ntev dua. Qhov no muaj feem xyuam rau cov hlau muaj pes tsawg leeg thiab microstructure. Yog li ntawd, hauv kev tsim khoom tiag tiag, cov neeg ua haujlwm yuav tsum kho cov txheej txheem tsis raws li cov khoom siv; ib qho -loj- haum- txhua txoj hauv kev tsis ua tau.
Nws puas tseem siv tau rau hauv kev tsim khoom siab heev?
Tej zaum koj yuav nug: Nrog kev nce siab ntawm kev tsim khoom ntse thiab cov khoom siv siab - kawg, puas tseem muaj qhov chaw rau " txheej txheem qub" no?
Cov lus teb yog yog.
Ntawm ib sab, blackening thiab bluing yog tshuaj oxidation txheej txheem. Cov cuab yeej siv yooj yim, kev ua haujlwm yooj yim, thiab nws tsis cia siab rau cov khoom siv hluav taws xob nyuaj lossis lub tshuab nqus tsev. Rau ntau lub chaw tsim khoom me thiab nruab nrab- qhov loj me, nws tseem yog tus nqi - xaiv tau zoo.
Ntawm qhov tod tes, nyob rau hauv qee theem ntawm kev tsim khoom siab heev, qhov nyias thiab ntom oxide zaj duab xis muaj qhov tshwj xeeb zoo. Piv txwv li, nyob rau hauv qhov kev kho deg ntawm precision qhov chaw, ib zaj duab xis uas tuab heev tuaj yeem cuam tshuam rau qhov haum; lub micron- theem tuab ntawm blackening thiab bluing yog txoj cai. Tsis tas li ntawd, nws tsis ua rau muaj kev pheej hmoo ntawm hydrogen embrittlement (ib qho teeb meem uas qee zaum tshwm sim hauv electroplating), ua rau nws ntseeg tau ntau dua hauv qee qhov siab - kawg teb.
Ntawm chav kawm, nws tsis yog tsis muaj nws drawbacks. Nws lub peev xwm tiv thaiv xeb yog txwv, thiab nws qhov hnav tsis kam yog qhov nruab nrab. Cov kev tsis txaus no tau nthuav dav hauv ib puag ncig hnyav. Yog li ntawd, cov qauv tam sim no yog: siv blackening / bluing raws li txheej txheej, ua ke nrog xeb - tiv thaiv roj los yog sealant, ntsuas tus nqi thiab kev ua haujlwm.
