Micro-scale Fracture Testing of Graded (Pt,Ni)Al Bond Coats
(2018-04-16)PtNiAl bond coats are diffusion aluminide coatings deposited on superalloy based turbine blades for oxidation resistance and improved adhesion between the substrate and the YSZ thermal barrier coating on top. They are ... -
Tensile Behavior Of Free-Standing Pt-Aluminide (PtAl) Bond Coats
(2016-05-03)Pt-aluminide (PtAl) coatings form an integral part of thermal barrier coating (TBC) systems that are applied on Ni-based superalloy components operating in the hot sections of gas turbine engines. These coatings serve as ... -
Testing Methodologies for Probing Site Specific Fatigue Response of Graded Coatings
Thermal barrier coating systems (TBC’s) employed in the high pressure turbine section of a modern aero-turbine engine serve as an example of constrained material systems used for engineering applications. TBC’s today are ...
