Technology Lecture: Gas Turbine Materials Research at the National Research Council Canada

Date: 06 Oct 2008 - 06 Oct 2008

Venue: SIMTech Auditorium, Level 3, Tower Block

This presentation provides an overview of the core research capabilities and activities on gas turbine materials and coatings at the NRC-IAR-SMPL. Observations of alloying and heat treatment effects, microstructures and mechanical properties of single crystal Ni-base superalloys and gamma titanium aluminide (TiAl) intermetallics will be discussed. Scope of the presentation includes the approach to qualifying high-temperature materials for specific engine component implementation through mechanical testing and physics-based life modelling along with examples demonstrating the challenges and solutions. For life management of service exposed engine critical components, spin rig testing is used to validate model predictions. Design, PVD fabrication and evaluation of gas turbine protective coatings will be presented. Specific examples of erosion-resistant coatings on compressor components will be given to illustrate technology innovations. The speakers will demonstrate the qualification testing procedure for coated compressor blades to achieve airworthiness certification.

About the Speakers
Dr Peter Au is a Senior Research Officer in Structures, Materials and Propulsion Laboratory at the Institute for Aerospace Research (IAR), NRC, Canada. His expertise includes fatique behaviour of metallic materials for aerospace and gas turbine applications; materials, repairs and protective coatings for gas turbine components; as well as qualification testing.

Dr Linruo Zhao is a Senior Research Officer and group leader in Structures, Materials and Propulsion Laboratory, Institute for Aerospace Research (IAR), NRC, Canada.  He has led the IAR coating team working on advanced nanocoatings for aerospace applications for the past seven years with support from the IAR-NIF program. He has published extensively and has been working closely with aerospace industry players. Many coatings were deposited using reactive sputtering and cathodic arc techniques. The coating characterisations involve high-angle and small-angle X-ray diffraction, microhardness testing and erosion testing.
