Thermal barrier coatings (TBC) are advanced material systems which are being widely employed in gas turbine engines. These coatings enable the turbine to operate at high temperatures thereby improving its efficiency. TBC coatings typically consist of two layers on the top of a substrate; a metallic bond coat of MCrAlY type where M is either Ni or Co or both, and a ceramic top coat.
My main research focus is on understanding the failure mechanisms in thermal barrier coatings (TBC) and develop a life model. The failure mechanisms are highly application and system dependent. I am trying to assess the damage evolution by studying the influence of different materials and deposition techniques on the failure mode of TBC systems. By using the available experimental data as input to a life model the goal is to develop a tool that can predict the lifetime of TBC systems.
This is a Vinnova project in collaboration with Siemens Industrial Turbomachinery and Beijing General Research Institute for Mining and Metallurgy in China.
I am looking for active collaboration with different researchers within the field of TBC. If you have any ideas or suggestions for collaboration please feel free to contact me.
