Blueing

steel baluuga ah - habka kiimikaad ee loo isticmaalo si ay u diyaariyaan dusha sare ee qaybaha steel ku khafiif ah film difaaca ee oxides birta Fe3O4. Magaca waxuu ka yimid meelaha midabka caan ka dib markii baaraandegidda (buluug-madow, oo tuke ah), sidoo kale loo yaqaan "blackening" ama "sinenie" guud ahaan, iyadoo aan loo eegin midabka - "qayilo". Filimku wuxuu keentay passivates dusha iyo ilaalinta qayb ka daxalka Hawada iyo saameynta kale ee warbaahinta xoqe.

Ka hor inta burnishing faahfaahsan steel hore loo diyaariyey, daahirisay miridhku mashiin safeeyey, degreased iyo pickled in xal acidic. Maaddooyinka noqon kartaa dareeraha ama khamriga. Iagu u baahan tahay inaad ka dusha ka saar oo dhan oxides aan loo baahnayn, tegaayo biraha dhashay.

Habka ugu fudud - burnishing saliid steel. Waxaa jira farsamooyin kala duwan, laakiin macnaha waa mid fudud: workpiece ah, lakabka khafiif ah oo saliid ah, ka dibna waa in la kululeeyo si 300-350 ° C. Subag, dubay marayo, ka baxo on dusha sare ee filimka xabagta ku. Laga soo bilaabo markii ugu horeysay ee daahan direyska waxaa ma aydin helin, sidaa darteed habka lagu celceliyo ilaa natiijada la rabay. Waxaa muhiim ah in la gaaro kululaynta uniform, haddii kale filimka tegi doonaa dhibco, iyo ma kululaado qaybo, sida waxaa laga yaabaa in deform ama lagu sii daayo. Dad badan ayaa ka dhigi qalad ah oo da'a item ee saliid ah preheated, waa khalad. Waa in si sax ah soo horjeeda: marka hore, si ay u marisaa, ka dibna dabka kulaalaya. Oil isticmaalin, ka gabbaldayaha si gudbinta ama engine. steel baluuga noocan oo kale ah waxay leedahay xoog u daahan hooseeyo. Waxaa keliya oo aan dhicin in ujeedooyinka madaxtooyada iyo difaaca.

Baluuga ah steel isticmaalaya sulphate birta, ferric chloride iyo nitric acid

Ujeedada this, halkii litir oo biyo ah loo baahan yahay si ay u milmaan 15 g of sulphate birta iyo 30 g of 10 g of acid. Shayga waa la hoos geliyey xalka la abuuri doonaa daahan daxalaystay, waxaa lagama maarmaan ah in ay xilliyo ka saarto burush iyo maquufin sii ilaa midabka doonayo ee film xabagta ku. Hadda dhowaad magaalo kasta waxaa jira dukaan lagu iibiyo kiimikooyinka, si aad u hesho iyaga waa mid fudud.

Baluuga ah steel isticmaalaya bichromate potassium (dichromate potassium). Ujeedada this, halkii litir oo biyo ah qasi jiray 200 garaam oo bichromate potassium, oo waxaa lagu Hawiyaha ee xalka loogu talagalay wax 20-30 daqiiqo. Ka dib markii laga saaray xal ka dibna la qalajiyey at heerkulka sare (foornada ama ka badan dhuxul). Geedi socodka lagu celceliyo ilaa midabka direyska buluug-madow. Markaas ka tirtiri piece of maro moofo saliid. Chrompick - reagent waa mid caadi ah, waxaa loo adeegsanayaa in industry maqaar.

Waayo, baluuga ah foosto qoriga lagu qaso hoos kululaynta 1 qayb by miisaanka of trichloride midabyo leh 3 qaybood oo saytuun ah oo saliid. Isku dar ah ayaa waxaa markaas codsatay in ay wax ka iyo oggol yahay in ay maalin taagan. Geedi socodka lagu celceliyo 10-12 jeer, ka dib markii taas oo foosto laga maydho dabadeed, qalajiyey iyo loo qoray. Color waa brown cagaaran.

Sida laga arki kor ku xusan, birta burnishing guriga - ilaa xad macquul ah iyo habka fudud. Waxaa lagu saleyn karaa alaabta wax sameeyey bir xaaladaha halkaas oo hababka kale ee ilaalinta daxalka, sida rinjiga, ma ku habboon yihiin.
