Title: The Innovative Contributions of David W. Hunt

Introduction

David W. Hunt is a notable inventor based in Orlando, FL, who has made significant contributions to the field of superalloy materials and their applications. With a total of 5 patents to his name, Hunt has developed innovative solutions that address critical challenges in the industry.

Latest Patents

One of Hunt's latest patents is focused on turbine superalloy component defect repair using low-temperature curing resin. This invention allows for the filling of voids, cracks, or similar defects in thermal barrier coated superalloy components, such as turbine blades or vanes, without the need to remove surrounding substrate material. The resin cures at a temperature below 200°C, eliminating the necessity for post void-filling heat treatment. The void-filled substrate and resin are subsequently coated with a thermal barrier coating.

Another significant patent by Hunt is a method for improving weldability in superalloy materials. This method involves depositing a weld strip of a weldable material onto a superalloy substrate using a spray deposition process. The process ensures that none or only a controlled amount of the substrate material is melted during the weld, maintaining the concentration of strengthening elements in the local melt. A diffusion heat treatment step may also be employed to enhance adhesion between the weld strip and the superalloy material.
