Blueing

Bluing steel - inkqubo imichiza lisetyenziselwe ukulungiselela kumphezulu iinxalenye zentsimbi kwi ezicekethekileyo yokhuselo umboniso of oxides Fe3O4 yentsimbi. Igama sivela ezingontsini umbala uphawu emva phambili (bamantshontsho emnyama, ihlungulu), eyaziwa ngokuba yi "blackening" okanye "sinenie" ngokubanzi, kungakhathaliseki ibala - "igcwala". Lo mboniso ngenxa passivates komhlaba kunye nokukhusela inxalenye ukusuka ngokudleka esesibhakabhakeni kunye nezinye iimpembelelo zosasazo entsimbini.

Phambi kokwenza burnishing iinkcukacha sentsimbi elungiselelwe ngaphambili, nyulu ukusuka irusi zoomatshini olubengezela kakuhle, degreased zifakwa kwi isisombululo asidi. Bamafutha inokuba kwisinyibilkisi okanye utywala. Nosipho kufuneka asuse onke oxides ngokungeyomfuneko ukusuka kumphezulu, eshiya metal engazali.

Indlela elula - burnishing ioli ngentsimbi. Kukho iindlela ezahlukeneyo, kodwa intsingiselo ilula: i workpiece, kukho umaleko obhityileyo yeoli, ngoko ke kufuneka lashushu 300-350 ° C. Ibhotolo, yosiwe nge, amagqabi phezu komhlaba ifilimu oxide. Ukususela kwixesha lokuqala yayisoma efanayo akukho bakufumana, ngoko ke le nkqubo iphindiwe de kwisiphumo oyifunayo. Kubalulekile ukuba kuzuzwe zokufudumeza uniform, kungenjalo mboniso kuhamba amabala, yaye musa shushu ngokugqithisileyo iindawo, njengoko ukugqabhuza, okanye akhululwe. Abantu abaninzi benza impazamo kwaye umyeke umba oli osuke, kuphosakele. Kufuneka ibe nto ichazwe kule vesi: okokuqala, ukunyhibhela, ngoko esotha. Oil ukusebenzisa nayiphi na, ukusuka kajongilanga yokudlulisa okanye injini. Ezo steel bluing i KHTML ngeso lenyama. Kuyinto sisebenza kuphela iinjongo zokuhombisa kunye zokhuselo.

Bluing steel usebenzisa sulphate intsimbi, ferric chloride kunye ne-nitric acid

Ukulungiselela le njongo, ilitha yamanzi nganye kufuneka liyichithe 15 g sulphate zentsimbi kunye-30 g ye-10 g ye acid. Le mveliso uvikivwa isicombululo iya kuyilwa ukutyabeka umhlwa, kuyimfuneko ukuba ixesha ukususa i ibhrashi kunye nkxu kuqhubeka de umbala wacela ifilimu oxide. Ngoku phantse yonke mzi kukho ivenkile ethengisa iikhemikhali, ngoko ukuze nabo kulula kakhulu.

Bluing steel usebenzisa potassium bichromate (potassium dichromate). Ukulungiselela le njongo, ilitha yamanzi bungxengwe 200 grams potassium bichromate nganye kwaye sokuvalwa isisombululo imizuzu 20-30 nto. Emva kokuba ukususwa evela isisombululo uze ome kwiqondo lobushushu eliphezulu (kwi-oveni okanye phezu kwamalahle). Le nkqubo iphindwe kude kube umbala efanayo oluhlaza-emnyama. Emva koko bekude isiziba somchako amafutha. Chrompick - reagent kuqhelekile kakhulu, lisetyenziswa kwishishini yesikhumba.

Kuba bluing iznto umpu zixubene phantsi ukufudumeza 1 inxalenye ngokobunzima trichloride kwistibhiya necandelo 3 yeminquma ioli. Lo mxube ngoko isicelo nomba kwaye avunyelwe ukuba eme ngeenyawo xa ngemini. Le nkqubo phindwa amaxesha 10-12, emva koko le bhafu kokuhlanjwa, womile kwaye olugudisiweyo. Umbala omdaka oluhlaza.

Njengoko kubonakala ngentla apha, burnishing intsimbi ekhaya - kakhulu kunokwenzeka kunye nenkqubo elula. It linokusetyenziswa naziphi iimveliso ezenziwe ngesinyithi kwiimeko apho ezinye iindlela zokukhusela umhlwa, ezifana ipeyinti, ayisayi kusebenza.
