Przedmiotem zgłoszenia jest sposób modyfikacji warstwy wierzchniej galwanicznych stopów Zn - Ni metodą utleniania anodowego, który polega na tym, że modyfikowany element zanurza się w alkoholowym roztworze wodorotlenku i polaryzuje się go anodowo, po czym poddaje utlenianiu anodowemu przy anodowej gęstości prądu 5 - 10000 mA/dm2 i napięciu 1 - 200 V, w czasie 1 - 120 minut i temperaturze od -30 do 80°C.The subject of the application is a method of modifying the surface layer of galvanic Zn - Ni alloys by anodic oxidation, which consists in the fact that the modified element is immersed in an alcohol hydroxide solution and polarized anodically, then subjected to anodic oxidation at anodic current density of 5 - 10000 mA / dm2 and voltage 1 - 200 V, for 1 - 120 minutes and temperature from -30 to 80 ° C.
