Title: Christoph Tonnes: Innovator in Thermal Turbo Machinery

Introduction

Christoph Tonnes is a notable inventor based in Brug, Switzerland. He has made significant contributions to the field of thermal turbo machinery, holding two patents that showcase his innovative approach to engineering challenges.

Latest Patents

One of his latest patents is focused on a friction-susceptible component of a thermal turbo machine. This invention involves a turbine blade of a gas turbine that is enhanced with an intermetallic felt. By incorporating this felt at the tip of the turbine blade, along with an optional ceramic coating, the design offers improved protection against thermal and mechanical effects, as well as enhanced oxidation resistance. Additionally, the arrangement of the intermetallic felt can be applied to the rotor or stator opposite the turbine blade or on the platform of the turbine blade.

Another significant patent by Christoph Tonnes is a process for treating the surface of a component made from a nickel-based superalloy prior to coating. This process is designed for high-temperature service applications. It involves depleting the outer surface of the component of elements such as aluminum, titanium, or chromium before applying the coating directly onto the depleted surface. This innovative approach minimizes the formation of a brittle gamma prime phase within the interdiffusion zone during the component's service life and can also be utilized to renew old damaged coatings.
