Latest Patents
One of Petersein's latest patents is focused on a hard, gold-colored under layer for a gold or gold-containing surface. This invention involves an underlayer made of at least one carbonitride of titanium, zirconium, hafnium, or vanadium, or hafnium nitride. This underlayer is designed to be placed beneath a surface layer that contains gold, providing a brilliance that closely resembles gold. This feature helps to disguise any spots on the surface layer that may wear away during use. The deposition of both the underlayer and surface layer can be achieved through a cathode vaporization process using corresponding metallic cathode targets in suitable atmospheres.
Another significant patent by Petersein is the electron beam vaporizer. This device includes a beam generator with a heated cathode, focusing means, and electromagnetic deflection means for guiding the beam. It features an exchangeable, fluid-cooled, and preferably rotatable vaporizing crucible that is associated with the beam generator. The crucible is designed with at least one depression in its base for vaporizing substances, and it has passages for coolant flow beneath the depression. The construction of the crucible base allows for a removable crucible head, ensuring efficient operation.
