Latest Patents
Franz's latest patents include a method for diamond coating substrates. This invention involves exposing a substrate in a vacuum atmosphere to a reactive gas mixture that is excited by a plasma discharge. The process utilizes a plasma beam in an evacuated receiver formed between a cathode chamber and an anode. The reactive gas mixture consists of a reactive gas and a working gas, with the hydrogen concentration ranging from 0 to 45 vol. %.
Another significant patent is a coating workpiece method that generates a beam of plasma in an evacuated container. In this method, workpieces are positioned radially offset from the beam axis, with their surfaces facing the axis. Fresh reactive gas is introduced into the container while consumed gas is removed. The coating material is deposited on the surfaces at a deposition rate of at least 400 nm/min, with a maximum surface temperature of 550°C.
