Mu makampani opanga ma electroplating, pulse power electroplating yakopa chidwi chifukwa cha ntchito yake yabwino kwambiri yopangira ma electroplating. Poyerekeza ndi DC electroplating yachikhalidwe, imatha kupeza ma coloration okhala ndi ma crystals abwino, ofanana, komanso oyera kwambiri. Zachidziwikire, pulse electroplating si yoyenera pazochitika zonse, ili ndi mawonekedwe akeake ogwiritsira ntchito.
Kodi ntchito zazikulu za pulse electroplating ndi ziti? Izi zimayamba ndi zabwino zake zingapo zazikulu.
1. Kupangika kwa kristalo kumakhala koyeretsedwa kwambiri
Pa nthawi yoyendetsa ma pulse, mphamvu yamagetsi imatha kufika kangapo kapena kuposerapo kakhumi kuposa mphamvu yamagetsi ya DC. Kuchuluka kwa mphamvu yamagetsi kumapangitsa kuti pakhale mphamvu yochulukirapo, zomwe zimawonjezera kwambiri kuchuluka kwa maatomu omwe amamatira pamwamba pa cathode. Kuchuluka kwa mphamvu ya ma nucleation kumathamanga kwambiri kuposa kuchuluka kwa ma crystal, zomwe zimapangitsa kuti pakhale utoto wofewa kwambiri. Mtundu uwu wa utoto uli ndi mphamvu yochulukirapo, kuuma kwambiri, ma pores ochepa, komanso kukana dzimbiri bwino, kukana kuvala, kuwotcherera, kuyendetsa magetsi, ndi zina zotero. Chifukwa chake, pulse electroplating imagwiritsidwa ntchito kwambiri m'magawo ogwira ntchito a electroplating omwe amafunikira magwiridwe antchito apamwamba.
2. Kutha bwino kufalitsa
Kupaka ma electroplating a pulse kuli ndi kuthekera kofalikira bwino, komwe ndikofunikira kwambiri pakupanga ma electroplating okongoletsera. Mwachitsanzo, pamene golide kapena siliva akuyika ma workpiece akuluakulu, kupaka ma electroplating a pulse kungapangitse mtundu kukhala wofanana komanso khalidwe likhale lokhazikika. Pakadali pano, chifukwa cha kuwonjezera njira yowongolera yakunja, kudalira kwa ubwino wa kupaka pa yankho la bafa kumachepa, ndipo kuwongolera magwiridwe antchito kumakhala kosavuta. Chifukwa chake, mu ma electroplating ena okongoletsa omwe amafunidwa kwambiri, kupaka ma electroplating a pulse kumakhalabe ndi phindu lake. Zachidziwikire, pa ma electroplating okongoletsera otetezedwa, monga njinga, zomangira, ndi zina zotero, sikofunikira kuzigwiritsa ntchito.
3. Kuyera kwambiri kwa zokutira
Mu nthawi yopuma, njira zina zabwino zochotsera mpweya m'madzi zimachitika pamwamba pa cathode, monga mpweya wa haidrojeni wothira kapena zinthu zodetsedwa zomwe zimachoka ndikubwerera ku yankho, motero zimachepetsa kusweka kwa haidrojeni ndikuwonjezera kuyera kwa chophimbacho. Kuyera kwakukulu kwa chophimbacho kumawonjezera magwiridwe ake ntchito. Mwachitsanzo, kuyika siliva wa pulse kumatha kusintha kwambiri kusinthasintha, kuyendetsa bwino, kukana mitundu, ndi zinthu zina, ndipo kuli ndi phindu lofunika kwambiri pazankhondo, zamagetsi, ndege, ndi zina.
4. Kuchuluka kwa madzi m'nthaka mwachangu
Anthu ena angaganize kuti pulse electroplating ili ndi chiŵerengero chotsika cha deposition kuposa direct current electroplating chifukwa cha kukhalapo kwa nthawi yozimitsa. Kwenikweni, sizili choncho. Chiŵerengero cha sedimentation chimadalira zomwe zimachitika chifukwa cha kuchuluka kwa current ndi mphamvu ya current. Pansi pa kuchuluka kwa current kofanana, pulse electroplating imayikidwa mwachangu chifukwa cha kubwezeretsa kuchuluka kwa ma ion m'dera la cathode panthawi yopuma, zomwe zimapangitsa kuti mphamvu ya current ikhale yokwera. Mbali imeneyi ingagwiritsidwe ntchito popanga electroplating mosalekeza yomwe imafuna deposition yofulumira, monga mawaya amagetsi.
Zachidziwikire, kuwonjezera pa ntchito zomwe zatchulidwazi, ndi kupita patsogolo kwa ukadaulo, magetsi a pulse akukulitsanso ntchito zawo m'magawo monga nanoelectrodeposition, anodizing, ndi electrolytic recovery. Pa electroplating yachikhalidwe, kusintha kugwiritsa ntchito pulse electroplating kuti muwongolere bwino ntchito sikungakhale kotsika mtengo.
