"Thermal Spray and Other Coatings for Gas Turbines – Selection and Application for OEM and Maintenance & Repair"

IGTI is proud to be partnering with ASM International to offer this Workshop

Saturday, June 12, 2010
Scottish Exhibition & Conference Center
Glasgow, Scotland

Course Overview
A wide variety of coatings are essential for the most efficient and effective design, construction, operation, and maintenance of gas turbine engines. Indeed, in some cases they are, in fact, enabling in achieving the most advanced, highly efficient and long lived engines. This course provides a brief overview of the various types of coatings used and then covers one of the most widely used and cost effective types of coatings - thermal spray - in more detail. The applications of the coatings throughout a gas turbine engine are illustrated and various thermal spray coating processes and properties are described. Particular attention is paid to the coatings used in the hot section of the engine. Finally, consideration is given to the selection and specification of coatings based on economics and performance.

Learning Objectives

Upon completion of this course, attendees will be able to:

• Describe thermal spray processes and coatings in comparison with other coatings
• Identify thermal spray coating properties and their use throughout gas turbine engines for a variety of purposes
• Recognize basic considerations required for quality control
• Select the best coatings for a given application based on both performance and economics

Who Should Attend
This course is designed for gas turbine engineers and scientists, engineering managers, and senior technicians from R&D, design, manufacturing, and maintenance including those with materials, mechanical, aero, or operations engineering backgrounds. Sales and marketing as well as purchasing professionals would gain valuable insights as well.

About the Instructor
Dr. Robert C. Tucker has over 40 years of experience in surface science and engineering. He retired from Praxair Surface Technologies as Corporate Fellow and Director of Business Development and Strategic R&D and is currently a consultant, primarily in the areas of surface science and engineering, new technology assessment, business development, and R&D management. Included in his tenure with Praxair was management of materials R&D including programs to develop materials resistant to high- and low-temperature wear, corrosion, high-temperature oxidation and sulfidation, thermal barriers, and composite materials. This work utilized thermal spray, physical and chemical vapor deposition, electrodeposition, laser cladding and other technologies.

Dr. Tucker received his BS in chemistry/mathematics from North Dakota State University and his MS and Ph.D. in metallurgy with minors in ceramics and nuclear science from Iowa State University. He has presented and/or published over 150 papers, has 23 U.S. patents with many foreign derivatives, and presented many short courses. Dr. Tucker is a Fellow of ASM International and was inducted into the ASM Thermal Spray Hall of Fame.
