Abstract
Et elektrolytisk bad for belegning. av gjenstander av aluminium og dets legeringer består i det vesentlige av en vandig oppløsning inneholdende et alkalimetallsilikat, eller hydrofluor-kiselsyre, et peroxyd, en vannopplselig carboxylgruppeholdig organisk syre og et vannoppløselig fluorid. En vanadium-forbindelse kan også være innbefattet i badet når de belagte gjenstander er beregnet å skulle anvendes for dekorative formål. Under prosessen blir aluminium-gjenstanden neddykket i badet, og et spenningssjokk påføres på denne ved å på-trykke et spenningspotensial mellom aluminiummetallet som tjener som anoden, og en katode neddykket i badet. Spen-ningspotensialet blir hurtig hevet til ca. 300 volt i løpet av ca. 2 til ca. 10 sekunder, og derefter blir spenningen øket gradvis til ca. 450 volt i løpet av noen få minutter inntil den ønskede beleggtykkelse er blitt dannet.
