Title: Genfa Hu - Innovator in Platinum Recovery Methods
Introduction
Genfa Hu is a notable inventor based in Singapore, SG, recognized for his contributions to the field of materials science and engineering. He holds a total of 4 patents, showcasing his innovative approaches to platinum recovery and surface protection methods.
Latest Patents
One of his latest patents is focused on platinum recovery methods. This invention outlines a method for recovering platinum from a coating on a component, specifically when the coating includes platinum aluminide. The process involves contacting the coating with a reagent solution that contains a reactive species capable of solubilizing an aluminum salt in water. This results in the formation of a platinum-rich residue on the component, which is then separated and collected. The reactive species may include hexafluorosilicic acid.
Another significant patent by Genfa Hu is for a method of selective surface protection of a gas turbine blade that has previously been in service. This method involves cleaning the gas turbine blade and depositing a platinum first layer on the airfoil and platform. Subsequently, a platinum second layer is deposited over the platform but not the airfoil. A platinum-aluminide protective coating is then formed by depositing an aluminum-containing layer over both the platform and airfoil, followed by interdiffusion of the platinum and aluminum.
