                            <p>Thermal barrier coatings (TBCs) are a type of coating used to provide thermal insulation in critical zone parts exposed to high temperatures, such as combustion chambers and turbine blades of gas turbine engines in the aviation industry. With the use of TBC systems, it is ensured that the surface temperature of metallic parts is increased and the efficiency of the turbine is increased, and the longer service life is achieved. The metallic material used as a substrate for a typical TBC system has a combination of metallic bond coating with MCrAlY content and yttria-stabilized zirconia coating (YSZ). In this study, metallic bond coatings with CoNiCrAlY content on Inconel 718 superalloy substrate were produced using atmospheric plasma spray (APS) coating method with a thickness of approximately 100 μm. CaO stabilized zirconia (CSZ) and MgO stabilized zirconia (MSZ) top ceramic coatings of TBC systems were produced using the APS method with a thickness of approximately 300 μm. Post-production microstructural and mechanical properties of different TBC systems produced were comparatively investigated and evaluated. Microstructural properties, and phase structures of the coatings were determined using scanning electron microscopy (SEM), elemental mapping, and X-Ray Diffractometry (XRD) analysis. Also, apart from microstructure and phase structures, porosity, hardness, and surface roughness properties were measured. The obtained analysis results, findings, and TBC systems were evaluated comparatively in the light of other relevant studies in the literature.</p></trans-abstract>

TBC sistemlerin kullanımı ile metalik parçaların yüzey sıcaklığının azaltılarak türbin verimliliğinin artırılması ve daha uzun kullanım ömrü elde edilmesi sağlanmaktadır. Bu çalışmada, Inconel 718 süper alaşım altlık malzeme üzerine CoNiCrAlY içeriğine sahip metalik bağ kaplamalar yaklaşık 100 μm kalınlığa sahip olarak atmosferik plazma sprey (APS) kaplama yöntemi kullanılarak üretilmiştir. TBC sistemlerinin CaO ile stabilize edilmiş zirkonya (CSZ) ve MgO ile stabilize zirkonya (MSZ) üst seramik kaplamaları yaklaşık 300 μm kalınlığa sahip olarak APS yöntemi kullanılarak üretilmiştir. Üretilen farklı TBC sistemlerinin üretim sonrası mikroyapısal ve mekanik özellikleri karşılaştırmalı olarak incelenerek, değerlendirilmiştir. Kaplamaların mikroyapısal özellikleri ve faz yapıları taramalı elektron mikroskobu (SEM), elemental haritalama ve X-Işını Difraktometresi (XRD) analizleri kullanılarak belirlenmiştir. Ayrıca, mikroyapı ve faz yapıları haricinde porozite, sertlik ve yüzey pürüzlülük özellikleri ölçülerek sunulmuştur. Elde edilen analiz sonuçları, bulgular ve TBC sistemleri literatürdeki diğer ilgili çalışmalar ışığında karşılaştırmalı olarak değerlendirilmiştir.</p></abstract>
