Processing Of Zirconia Based Honeycombs And Evaluation Of Thermo Mechanical Properties
(2010-08-16)Ceramic cellular solids, mainly honeycombs and foams, are a novel class of composite materials where one phase is an interconnected network of solid struts or plates and the other one an empty phase or possibly a fluid. ... -
Pseudo-binary and Pseudo-ternary diffusion couple methods for understanding the growth of interdiffusion zone between bond coat and superalloys
Ni-based superalloys are widely used in jet engine applications. Bond coats are applied to these alloys for protection during service in a very harsh environment at high operating temperature. The addition of Pt to the ... -
Reactive Hot Pressing Of ZrB2-Based Ultra High Temperature Ceramic Composites
(2010-10-08)Zirconium- and titanium- based compounds (borides, carbides and nitrides) are of importance because of their attractive properties including: high melting temperature, high-temperature strength, high hardness, high elastic ... -
Studies on Internal Reforming Solid Oxide Fuel Cell
Renewable energy becomes inevitable for future energy needs. Accordingly, researchers are exploring possible alternatives to conventional fuel based internal combustion engines. In recent years, Bio-fuel (methane/ethanol) ... -
Study Of Fracture Properties Of NiAl Bond Coats On Nickel Superalloy By Three Point Bending Of Microbeams
(2009-05-13)The continuing quest for higher performance levels of modern gas turbine engines has been accompanied by the demand for higher engine operating temperatures. The use of Thermal Barrier Coatings (TBCs) enabled gas turbines ... -
Study On Reactive Hot Pressing Of Zirconium Carbide
(2017-04-27)Group IV transition metal carbides are promising materials for high temperature structural application, due to their unique sets of properties such as high melting temperature, high temperature strength, hardness, elastic ... -
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 ... -
Uniaxial Fatigue Behavior of Freestanding Platinum-Aluminide (PtAl) Bond Coat
Pt-aluminide (PtAl) bond coat is used as a part of Thermal Barrier Coating (TBC) system on Ni-base superalloy components in advanced gas turbine aeroengines. The thickness of B2-NiAl intermetallic based diffused coating ...
