Latest Patents
Erdmann's latest patents include innovations related to the production of black surface layers on light metals. The first patent describes a cyanide-free electrolyte that is harmless to both the environment and health. This invention allows for the creation of deeply-black and adhesive surface layers on light metals, particularly titanium, which maintain their properties even under extreme temperature changes. The anodic oxidation process used, known as the ANDF-method, results in layers that are X-amorphous and exhibit ideal optically isotropic behavior. The electrolyte consists of an ammoniacal solution of potassium dihydrogenphosphate and potassium chromate, ensuring homogeneity by avoiding fluoride ions and utilizing acetate ions.
The second patent also focuses on a cyanide-free electrolyte for producing black surface layers on light metals. Similar to the first, it emphasizes the importance of environmental safety and health. The layers produced through this method also demonstrate high thermovacuum stability and are composed of titanium, chromium, and copper in specific ratios.
