Phekolo ea ho qeta bokaholimo e theha mokhoa oa tšebetso oa lera holim'a thepa ea substrate, e nang le thepa e fapaneng ea mochini, ea 'mele le ea lik'hemik'hale ka thepa ea substrate.Sepheo sa phekolo ea holim'a metsi ke ho finyella ho hanyetsa ha sehlahisoa, ho hanyetsa ho roala, mokhabiso kapa litlhoko tse ling tse khethehileng tsa ts'ebetso.
Ho latela ts'ebeliso, mokhoa oa kalafo o kaholimo o ka aroloa ka mekhahlelo e latelang.
Mokhoa oa electrochemical
Mokhoa ona ke ts'ebeliso ea karabelo ea elektrode ho theha sekoaelo sebakeng sa workpiece.Mekhoa e meholo ke:
(A) Electroplating
Ka tharollo ea electrolyte, workpiece ke cathode, e ka etsang filimi ea ho roala holim'a metsi tlas'a ketso ea ka ntle, e bitsoang electroplating.
(B) Anodization
Ka tharollo ea electrolyte, workpiece ke anode, e ka etsang lera anodized holim'a metsi tlas'a ketso ea ka ntle hona joale, e bitsoang anodizing, tse kang aluminium alloy anodizing.
Anodization ea tšepe e ka etsoa ka mekhoa ea lik'hemik'hale kapa tsa electrochemical.Lik'hemik'hale mokhoa o beha workpiece ka mokelikeli anodized, e tla theha anodized filimi, tse kang tšepe bluing kalafo.
Mokhoa oa lik'hemik'hale
Mokhoa ona o sebelisa ho sebelisana ha lik'hemik'hale ntle le hona joale ho theha filimi ea ho roala holim'a workpiece.Haholo-holo mekhoa ke:
(A) phekolo ea filimi ea phetoho ea lik'hemik'hale
Ka tharollo electrolyte, workpiece ho ba sieo ha ka ntle hona joale, ka tharollo ea lintho tsa lik'hemik'hale le workpiece ho sebelisana ho etsa barbotage ka holim'a tshebetso lona, e tsejoang e le phekolo ea lik'hemik'hale sokoloha filimi.
Hobane tšebelisano pakeng tsa lintho tsa lik'hemik'hale tsa tharollo le workpiece ntle le hona joale ka ntle e ka etsa barbotage filimi holim'a workpiece holim'a, e leng bitsoa lik'hemik'hale sokoloha filimi.Joalo ka bluing, phosphating, passivating, kalafo ea letsoai la chromium joalo-joalo.
(B) Ho roala ka motlakase
Ka tharollo ea electrolyte ka lebaka la ho fokotseha ha lintho tsa lik'hemik'hale, lintho tse ling li kenngoa holim'a sebaka sa mosebetsi ho etsa mokhoa oa ho roala, o bitsoang electroless plating, joalo ka electroless nickel plating, electroless copper plating.
Mokhoa oa ho sebetsa ka mocheso
Mokhoa ona o etsa hore thepa e qhibilihe kapa e phalle ka mocheso maemong a phahameng a mocheso ho theha filimi ea ho roala holim'a workpiece.Haholo-holo mekhoa ke:
(A) Ho qoelisoa ho chesang
Kenya likarolo tsa tšepe ka har'a tšepe e qhibilihisitsoeng ho etsa filimi ea ho roala holim'a sebaka sa mosebetsi, se bitsoang hot-dip plating, joalo ka hot-dip galvanizing, aluminium e chesang joalo-joalo.
(B) Ho fafatsa ka mocheso
Mokhoa oa ho atomizing le ho fafatsa tšepe e qhibilihisitsoeng holim'a sebaka sa mosebetsi ho etsa filimi ea ho roala e bitsoa ho fafatsa ka mocheso, joalo ka ho fafatsa ka mocheso oa zinki, ho fafatsa ka mocheso oa aluminium joalo-joalo.
(C) Ho hatisa ho chesang
The tšepe foil futhumatsang, khatello e koahela holim'a workpiece ho theha tshebetso barbotage filimi, e neng e bitsoa chesang stamping, tse kang chesang foil foil joalo-joalo.
(D) Phekolo ea mocheso oa lik'hemik'hale
Ho kopana le lik'hemik'hale 'me u lumelle likarolo tse ling hore li kene sebakeng sa mosebetsi sebakeng se phahameng sa mocheso, se neng se bitsa kalafo ea mocheso oa lik'hemik'hale, joalo ka nitriding, carburizing, joalo-joalo.
Mekhoa e meng
Haholo-holo mochine, lik'hemik'hale, electrochemical, mokhoa oa 'mele.Mekhoa e meholo ke:
(A)Painting coating (B) Strike plating (C) laser surface finish (D) Super-hard film technology (E) Electrophoresis and electrostatic spraying
