Li-tag tsa Sehlahisoa
TLHALOSO:
Electrode e koahetsoeng ke COBALTARD 1FC ke motsoako o tloaelehileng oa ho thatafala o phahameng ka ho fetisisa sehlopheng sa metsoako ea cobalt e sebelisetsoang ho robeha ha mocheso o phahameng o amanang le ho robeha. Li-deposit tsa motsoako ona li na le bongata bo boholo ba lik'habohaedreite tsa chromium tse amang khanyetso e ikhethang ea ho robeha ha mocheso. Ho eketsoa ha tungsten ho eketsa ho thatafala ha mocheso o phahameng le ho tiea ha matrix bakeng sa sekhomaretsi se setle le khanyetso e tiileng ea ho robeha ha likaroloana. E hokahana hantle le litšepe tsohle, ho kenyeletsoa le tse sa hloekang.
