Chithandizo chomaliza chapamwamba ndikupanga njira yosanjikiza pamwamba pa gawo lapansi, lomwe lili ndi mawotchi osiyanasiyana, thupi ndi mankhwala okhala ndi gawo lapansi.Cholinga cha chithandizo chapamwamba ndikukwaniritsa kukana kwa dzimbiri, kukana kuvala, zokongoletsera kapena zofunikira zina zapadera.
Kutengera ndikugwiritsa ntchito, njira yochizira pamwamba imatha kugawidwa m'magulu otsatirawa.
Electrochemical njira
Njira iyi ndikugwiritsa ntchito electrode reaction kuti apange zokutira pamalo ogwirira ntchito.Njira zazikulu ndi izi:
(A) Electroplating
Mu njira ya electrolyte, workpiece ndi cathode, yomwe imatha kupanga filimu yophimba pamwamba pa zochitika zakunja, zomwe zimatchedwa electroplating.
(B) Anodization
Mu njira electrolyte, workpiece ndi anode, amene akhoza kupanga wosanjikiza anodized padziko pansi zochita za kunja panopa, amene amatchedwa anodizing, monga zotayidwa aloyi anodizing.
The anodization wa zitsulo akhoza kuchitidwa ndi mankhwala kapena electrochemical njira.Mankhwala njira ndi kuika workpiece mu anodized madzi, izo kupanga anodized filimu, monga zitsulo bluing mankhwala.
Chemical njira
Njirayi ikugwiritsa ntchito kuyanjana kwamankhwala popanda panopa kupanga filimu yophimba pamwamba pa workpiece.Njira zazikulu ndi izi:
(A) mankhwala kutembenuka filimu mankhwala
Mu njira electrolyte, workpiece pakalibe kunja panopa, ndi yankho la zinthu mankhwala ndi workpiece mogwirizana kupanga ❖ kuyanika pamwamba ndondomeko yake, wotchedwa mankhwala kutembenuka filimu mankhwala.
Chifukwa kugwirizana pakati pa zinthu mankhwala a njira ndi workpiece popanda kunja panopa amene angapange ❖ kuyanika filimu pa workpiece pamwamba, amene amatchedwa mankhwala kutembenuka filimu.Monga bluing, phosphating, passivating, chromium mchere mankhwala ndi zina zotero.
(B) Zovala zopanda magetsi
Mu njira ya electrolyte chifukwa cha kuchepa kwa zinthu za mankhwala, zinthu zina zimayikidwa pamwamba pa workpiece kuti apange njira yokutira, yomwe imatchedwa electroless plating, monga electroless nickel plating, electroless copper plating.
Thermal processing njira
Njirayi ikupanga kusungunuka kwazinthu kapena kufalikira kwamafuta mumikhalidwe yotentha kwambiri kuti ipange filimu yokutira pamwamba pa workpiece.Njira zazikulu ndi izi:
(A) Kutentha kwa dip
Ikani zitsulo muzitsulo zosungunula kuti mupange filimu yokutira pamwamba pa workpiece, yomwe imatchedwa kutentha-kuviika plating, monga galvanizing yotentha, aluminium yotentha ndi zina zotero.
(B) Kupopera mbewu kwa kutentha
Njira ya atomizing ndi kupopera zitsulo zosungunuka pamwamba pa workpiece kuti apange filimu yokutira imatchedwa kupopera mankhwala otentha, monga kupopera mankhwala a zinki, kupopera mankhwala a aluminium ndi zina zotero.
(C) Kupondaponda kwamoto
The zitsulo zojambulazo mkangano, kupsyinjika chivundikiro pamwamba pa workpiece kupanga ❖ kuyanika filimu ndondomeko, amene amatchedwa otentha masitampu, monga otentha zojambulazo zojambulazo ndi zina zotero.
(D) Mankhwala kutentha mankhwala
Kupanga ma workpiece kukhudzana ndi mankhwala ndi kulola zinthu zina mu workpiece pamwamba kutentha, amene amatchedwa mankhwala kutentha mankhwala, monga nitriding, carburizing ndi zina zotero.
Njira zina
Makamaka makina, mankhwala, electrochemical, thupi njira.Njira zazikulu ndi izi:
(A)Kupaka utoto (B) Kupaka chitsulo (C) Kumaliza kwa laser pamwamba (D) Ukadaulo wafilimu wolimba kwambiri (E) Electrophoresis ndi kupopera mbewu kwa ma electrostatic
