Title
(EN) Method of producing an interference coating
(PL) Sposób wytwarzania powłoki interferencyjnej
Abstract
(PL) Przedmiotem zgłoszenia jest sposób wytwarzania powłoki interferencyjnej na powierzchni wyrobu ze stopu albo stopów aluminium obejmujący anodowanie i barwienie elektrochemiczne z użyciem prądu przemiennego polega na tym, że elektrolit stosowany podczas barwienia elektrochemicznego zawiera siarczan (VI) miedzi (II) w ilości od 1 do 100 g/l, kwas borowy w ilości od 1 do 40 g/l i kwas winowy w ilości 0,1 g do 20 g/l.
