Title: Innovations by Shih Tung Ngiam

Introduction

Shih Tung Ngiam is a notable inventor based in Singapore, recognized for his contributions to the field of materials science and engineering. He holds 2 patents that focus on advanced methods for enhancing the performance and longevity of superalloy substrates.

Latest Patents

One of his latest patents is titled "Method for renewing diffusion coatings on superalloy substrates." This innovative method involves the controlled removal of a portion of a diffusion coating from the outer surface of a nickel-containing superalloy article. The process includes contacting the coated superalloy article in a preselected chemical stripping solution for a specific duration, allowing for the removal of only the outer aluminide layer while preserving the underlying diffusion layer. After neutralizing the stripping solution, the article can be inspected and repaired as necessary, with the aluminide outer layer restored using conventional methods.

Another significant patent is "Coating and method for minimizing consumption of base material during high temperature service." This patent presents an improved coating and method that minimizes substrate material consumption during high-temperature applications. It involves the formation of an intermediate metal aluminide layer by adding a layer of nickel or cobalt, or a combination of both, to the substrate material through processes such as electroplating or electroless plating. A diffusion aluminide is then formed at the surface by exposing the plated substrate to a source of aluminum at elevated temperatures.
