ABSTRACT:

A Case Study in the Development of Chrome Free Diffusion Coatings for Gas Turbine Hot Gas Path Components

This paper will detail the development of totally chrome free diffusion coatings as replacement for traditional chrome 6 containing products, to include Sermaloy J and Ipal.

The many pitfalls encountered on the development path will be discussed before the project conclusion with an internationally approved coating.
