TSS PRE-SYMPOSIUM EDUCATION COURSE
October 13-14, 2008

Materials and Processes for High Temperature
Gas Turbine Components

Instructor:
Dr. Donald Boone
President
BWD Turbines Limited

Overview:
This course will help participants to develop a firm understanding of the critical materials, processes, and applications of gas turbine components operating at the highest temperatures in the turbine section.
Coverage includes design requirements, materials and processing details, protection system requirements, degradation sequences and most important, repair and refurbishment strategies that provide a background for both the equipment user and the coatings processor.

Learning Objectives:

• Describe the history of gas turbine components and needs
• Identify the unique and vital superalloy materials and processes that make these components viable
• Discuss degradation modes and potential refurbishment strategies
• Describe protective coating requirements, history and strategies
• Assess coating processing needs and opportunities

Who Should Attend:
The course is structured for gas turbine designers, users, materials and processing personnel, both developmental and applications, practicing engineers and managers. It is also beneficial for educators and sales people whose responsibilities involve critical technical decisions in this high cost area of the gas turbine.
Coatings equipment suppliers, processors, and repairers can expand their capabilities and abilities by understanding the history, needs, and present situation of the industry.
