Momwe mungathanirane ndi blackening ya stee

Pansi pa chilengedwe, filimu ya 10-20A oxide idzapangidwa pamwamba pazitsulo zazitsulo chifukwa cha kukhudzana ndi mpweya mumlengalenga.Panthawi yopanga filimu yachilengedwe, malingana ndi momwe chitsulocho chimapangidwira, mawonekedwe a pamwamba ndi makutidwe ndi okosijeni, mafilimu ena a oxide omwe amapangidwa amakhala ochepa thupi, ena amakhala owundana komanso athunthu, ndipo ena ndi otayirira komanso osakwanira.Nthawi zambiri, filimu yachilengedwe ya oxide yomwe imapangidwa silingalepheretse zitsulo kuti zisawonongeke.
Pali njira zambiri zochizira makutidwe ndi okosijeni pazitsulo, kuphatikiza makutidwe ndi okosijeni amchere, okosijeni wopanda mchere wamchere, kutentha kwambiri kwa gasi oxidation ndi electrochemical oxidation.Pakali pano, njira ya alkaline chemical oxidation imagwiritsidwa ntchito kwambiri m'makampani.(Komanso njira ya asidi oxidation)
Makhalidwe a filimu ya okusayidi: mtundu wokongola, palibe embrittlement wa haidrojeni, elasticity, filimu yopyapyala (0.5-1.5um), palibe zotsatira zazikulu pa kukula ndi kulondola kwa zigawozo, komanso zimakhala ndi zotsatirapo zake pochotsa kupsinjika komwe kumachitika pambuyo pa kutentha. chithandizo.
Chithandizo chakuda ndi mtundu wa njira yochizira makutidwe ndi okosijeni pamtunda.Zigawo zachitsulo zimayikidwa mu njira yowonongeka kwambiri ya alkali ndi okosijeni, kutentha ndi okosijeni pa kutentha kwina, kotero kuti wosanjikiza wa yunifolomu ndi wandiweyani wachitsulo amapangidwa ndikumangirizidwa mwamphamvu kuzitsulo zapansi.Njira ya ferric oxide film imatchedwa blackening.Chifukwa cha kukhudzidwa kwa zinthu zosiyanasiyana zomwe zikugwira ntchito, mtundu wa filimuyi ndi wakuda, wakuda, wofiira, wofiira, wofiira, ndi zina zotero.
Cholinga cha chithandizo chakuda chimakhala ndi mfundo zitatu izi:
1. Anti-dzimbiri zotsatira pa zitsulo pamwamba.
2. Wonjezerani kukongola ndi kuwala kwa zitsulo pamwamba.
3. Kuwotcha pa nthawi yakuda kumathandiza kuchepetsa nkhawa mu workpiece.
Chifukwa chithandizo chakuda chimakhala ndi zotsatira zomwe tazitchula pamwambapa, mtengo wake ndi wochepa, ndipo khalidweli ndi lokwera, limagwiritsidwa ntchito kwambiri pazitsulo zazitsulo komanso kupewa dzimbiri pakati pa njira.
