Title: Rolf-Jorg Dunker: Innovator in Etch Solutions for Turbine Blades
Introduction
Rolf-Jorg Dunker is a notable inventor based in Dachau, Germany. He has made significant contributions to the field of etch solutions, particularly in the context of turbine blade maintenance. His innovative approach has led to the development of a unique etch solution that addresses corrosion issues in power units.
Latest Patents
Dunker holds a patent for an etch solution and associated process for the removal of protective metal. This solution is designed to effectively remove metallic layers that protect against corrosion caused by hot gases. The etch solution comprises a salt solution, specifically hydrogen sulfate, in concentrations ranging from 5 to 45% by weight, along with an inhibitor present at 0.5 to 10% by weight. The formulation ensures that at least 50% by weight of the total etch solution consists of water. This innovative solution is particularly effective in removing layers, such as MCrAlY, from turbine blades made of titanium, cobalt, or nickel alloys.
