ITSC 2017, Thermal Spray 2017: Proceedings from the International Thermal Spray Conference, 296-301, June 7–9, 2017,
... Abstract A method measuring the thermal conductivity and the interfacial thermal resistance of thermal barrier coatings (TBCs) which consist of metallic bond-coats (BCs) and ceramics top-coats (TCs) on superalloys was newly developed. It was based on the areal heat diffusion time method...

ITSC 2017, Thermal Spray 2017: Proceedings from the International Thermal Spray Conference, 843-848, June 7–9, 2017,
... Abstract Thermal insulation performance is a measurement of the thermal protection offered by the thermal barrier coatings (TBCs) to the substrate, therefore, it is essentially important to compare different double ceramic layer (DCL) TBCs on the premise of the same thermal resistance...

ITSC 2017, Thermal Spray 2017: Proceedings from the International Thermal Spray Conference, 861-866, June 7–9, 2017,
... Abstract Thermal cycle lifetime is essentially important to the application of thermal barrier coatings (TBCs) on the premise of the same thermal resistance. In this study, equivalent thermal insulation conception is introduced to the design of dense vertical crack (DVC) structured TBCs...

ITSC 2009, Thermal Spray 2009: Proceedings from the International Thermal Spray Conference, 997-1001, May 4–7, 2009,
... Abstract “Testing Method for Thermal Cycle and Thermal Shock Resistance of Thermal Barrier Coating (TBC)” is a Japanese Industrial Standard (JIS) newly established by the Minister of Economy, Trade, and Industry in 2008, after deliberations by Japanese Industrial Standards Committee...

ITSC1998, Thermal Spray 1998: Proceedings from the International Thermal Spray Conference, 1265-1269, May 25–29, 1998,
... heat treatments were carried out to study the thermal stability of the methanol milled and cryomilled Inconel 718 powders, as well as the HVOF Inconel 718 coatings. All nanocrystalline Inconel 718 powders and coatings studied herein exhibited significant thermal stability against grain growth...

ITSC1998, Thermal Spray 1998: Proceedings from the International Thermal Spray Conference, 1617-1622, May 25–29, 1998,
... Abstract In the Brite Euram Project COMBCOAT Thermal Barrier Coatings for improved thermal protection with a thickness up to 2 mm have been developed for combustor applications. As a typical experiment to evaluate the quality of the coatings, life cycles to spallation by means of thermal...

ITSC2000, Thermal Spray 2000: Proceedings from the International Thermal Spray Conference, 173-180, May 8–11, 2000,
... Abstract To determine the effect of bond coat oxidation on the coating life, thermal shock testing were performed, using three different thermal cycles. The failure mode and crack paths were investigated in scanning electron microscope. A finite element model was developed to simulate...

ITSC2000, Thermal Spray 2000: Proceedings from the International Thermal Spray Conference, 1057-1060, May 8–11, 2000,
... Abstract Thermal barrier coatings have been extensively used in several industrial segments. The material used as an insulator in such systems has been partially stabilized zirconia (PSZ) plasma sprayed over a metallic bond coat layer. The ceramic layer is usually porous, thus improving...

ITSC 2002, Thermal Spray 2002: Proceedings from the International Thermal Spray Conference, 777-781, March 4–6, 2002,
... Abstract This paper presents the results of long-term thermal cycling tests on plasma-sprayed thermal barrier coatings, including coating samples produced with functionally graded materials. The role of oxidation is also considered based on the results of elemental analysis. The authors explain...
