Latest Patents

Nitzsche's latest patents focus on the plasma descaling of metals. The first patent describes a plasma descaling process that selectively removes surface oxides from structural metal surfaces, especially titanium and its alloys. This innovative method is self-limiting, avoiding cracking problems associated with intergranular attack. The preferred embodiment utilizes a fluoride plasma that reacts with surface oxides on titanium alloys, effectively removing scale and alpha case without damaging the underlying crystalline metal. The result is a metal surface that is free of scale and alpha case, as well as intergranular attack.

The second patent outlines a method for removing surface scale from titanium or titanium alloy substrates. This method involves heating the substrate to a temperature between 100°C and 600°C, followed by exposure to a plasma formed from gases such as CF₄ and SF₆. The plasma reacts with the surface scale, ensuring uniform removal without attacking the underlying crystalline structure. This innovative approach allows for effective surface treatment while maintaining the integrity of the substrate.
