Blueing

steel Bluing - inqubo yamakhemikhali esetshenziswa ukulungiselela ebusweni izingxenye steel phezu mncane ifilimu zokuzivikela ka oxides Fe3O4 yensimbi. Igama sivela isici umbala izingxenye ngemva kokucubungula (bluish-emnyama, amagwababa), owaziwa ngokuthi "blackening" noma "sinenie" ngokuvamile, kungakhathaliseki umbala - "namachibi". Le filimu okuholela passivates kwamanzi futhi ukuvikela ingxenye kusuka ukugqwala emkhathini futhi imiphumela abezindaba ezonakalisayo.

Ngaphambi kokwenza burnishing steel ngokuningiliziwe ngaphambilini walungisa, wahlanza kusuka ukugqwala athutha emihle, degreased futhi zicwiliswe e ikhambi ene-asidi. Degreasing kungaba kuphela noma utshwala. Etching udinga ukususa ebusweni bonke oxides engadingekile, kusale metal elingenalutho.

Indlela elula - burnishing uwoyela steel. Kukhona amasu ahlukene, kodwa incazelo ilula: workpiece, ungqimba ezondile uwoyela, khona-ke kufanele ukufuthelana 300-350 ° C. Ibhotela, ngosile ngokusebenzisa, eshiya phezu ifilimu oxide. Kusukela okokuqala enamathela iyunifomu akuyona etholwe, ngakho inqubo iyaphindwa kuze elamukelekile. Kubalulekile ukufeza Ukushisa umfaniswano, kungenjalo ifilimu ngizoya izindawo, futhi musa overheat izingxenye, njengoba kungase deform noma akhululwe. Abantu abaningi bavame ukwenza iphutha bese uphonsa into uwoyela osuke usushisa kakade, akulungile. Kufanele kube yizinhlamvu okuphambene: kuqala, ukufezekisa ke ukufudumala. Amafutha ukusebenzisa noma isiphi, kusukela sunflower nokudlulisela noma injini. steel okunjalo bluing has a amandla ongaphakeme enamathela. Kuyinto esebenzayo kuphela zokuhlobisa futhi uyavikela.

Bluing steel usebenzisa yensimbi sulphate, ferric chloride futhi nitric acid

Ngenxa yale njongo, ilitha lamanzi ngalinye kwakudingeka ukuncibilikisa 15 g yensimbi sulphate no-30 g 10 g we acid. Umkhiqizo lehliselwa singene ikhambi uzobe kwakhiwa enamathela ibuthuntu, kubalulekile ukususa ngezikhathi shayela futhi cwilisa uqhubeke kuze kube umbala wayefisa ifilimu oxide. Manje, cishe njalo edolobheni kukhona esitolo ukuthi uthengisa amakhemikhali, ngakho ukuze uzenze kulula.

Bluing steel usebenzisa potassium bichromate (potassium dichromate). Ngenxa yale njongo, ilitha lamanzi buhlanjululwe 200 amagremu potassium bichromate ngayinye futhi ebhapathizwa isixazululo imizuzu 20-30 lento. Ngemva ukususwa kusukela isixazululo bese omisiwe ngamazinga ashisa kakhulu (kuhhavini noma phezu kwamalahle). Le nqubo ibizwa eziphindaphindiwe kuze iyunifomu nombala oluhlaza njengesibhakabhaka-black. Khona-ke ukusula indwangu ezinamafutha akahle. Chrompick - reagent kuvamile, isetshenziswa embonini lesikhumba.

Ukuze bluing isibhamu imiphongolo axutshwa ngaphansi Ukushisa 1 okuyingxenye ngesisindo sezinti trichloride antimony nge izingxenye 3 omnqumo uwoyela. Ingxube lase ke ukusetshenziswa entweni futhi avunyelwe ukuba amele ngosuku. Le nqubo ibizwa liphindwe izikhathi 10-12, ngemva kwalokho umgqomo is wageza, omisiwe futhi iphucuziwe. Umbala kuyinto brown ogqamile.

Njengoba ungase ubone ngenhla, steel burnishing ekhaya - ngempela okusebenzayo futhi inqubo elula. It singasetshenziswa iyiphi imikhiqizo ezenziwe ngensimbi ezimweni lapho ezinye izindlela yokuvikela ukugqwala, ezifana upende, akuzona osebenzayo.
