Latest Patents
Dorith Schmidt's latest patents focus on the production of black surface layers on light metals. The first patent describes a cyanide-free electrolyte that is harmless to the environment and health. This invention allows for the creation of deeply-black and adhesive surface layers on light metals, such as titanium, which maintain their properties even under extreme temperature changes. The anodic oxidation process by spark discharge, known as the ANDF-method, is utilized to achieve these results. The layers produced are X-amorphous and exhibit ideal optically isotropic behavior regarding radiation reflection. The electrolyte consists of an ammoniacal solution of potassium dihydrogenphosphate and potassium chromate, ensuring homogeneity by avoiding fluoride ions and using acetate ions.
The second patent also pertains to the production of black surface layers on light metals, utilizing a similar cyanide-free electrolyte. This invention emphasizes the same environmental and health benefits, while also ensuring high thermovacuum stability due to minimal gas evolution. The composition of the layers includes titanium, chromium, and copper in specific ratios, further enhancing their performance.
