Lisebelisoa tse sebetsang: tšepe e ntšo, koporo le koporo ea alloy nickel-plated, chrome-plated bottom layer.
Nickel plating:
Nickel e na le botsitso bo botle ba lik'hemik'hale sepakapakeng le lye, 'me ha ho bonolo ho fetola' mala, empa e qhibiliha habonolo ka ho hlapolla nitric acid.Ho bonolo ho feta ka har'a acid e ngata ea nitric, 'me bofokoli ba eona ke porosity.Ho hlola bofokoli bona, ho ka sebelisoa tšepe e nang le mekhahlelo e mengata, 'me nickel ke lera le bohareng.Sekhahla sa nickel plating se na le boima bo phahameng, se bonolo ho bentša, se na le khanya e phahameng ea khanya 'me se ka eketsa ponahalo le ho hanyetsa,' me se na le khanyetso e ntle ea kutu.
Lisebelisoa tse sebetsang: li ka beoa holim'a lisebelisoa tse fapaneng, tse kang: li-alloys tse thehiloeng ho tšepe-nickel, li-alloys tse thehiloeng ho zinki, li-alloys tsa aluminium, likhalase, ceramics, polasetiki, li-semiconductors le lisebelisoa tse ling.
