“…This is also known as an “electron evaporation system”, since the incident electron beam evaporates the coating (source) material and deposits on the substrate. Coating materials used for EB-PVD contain but are not restricted to ceramic, titanium, and zirconium, with aluminum titanium nitride (TiAlN) YSZ being the standard TBC material for turbine applications fabricated in this manner . Coating thickness can range from 100 to 300 nm to a few micrometers and can enhance the substrate’s thermal and optical properties .…”

Today's competitive world economy is creating an indispensable demand for increased efficiency of engineering components that operate in harsh environments (i.e., very high-temperature, corrosive, or neutron irradiation environments), for applications in the energy, automotive, aerospace, electronics, and power industries. Increased research is being done on thermal barrier coatings (TBCs) for protecting such components, since the versatility of manufacturing techniques and the scale of deployment result in increased life, economics, performance, and durability. This review focuses on the advances that led to using TBCs for component life extension and, more recently, as an integral part of advanced component design for high-temperature and other types of harsh environments, such as those found in nuclear-related applications. Factors that led to state-of-the-art advanced coating-fabrication techniques [e.g., electron-beam physical vapor deposition (EB-PVD), plasma spray deposition, and electrophoretically deposited TBCs, as well as functionally graded material (FGM) manufacturing] have also been emphasized in current coating R&D. This review explores the current state of TBCs, i.e., the latest advances regarding their fabrication and performance, associated challenges, and recommendations for their future use in aerospace, nuclear, high-temperature, or otherwise harsh environments.

“…17,18 Researchers have shown that combining manganese and cobalt in spinel coatings results in exceptional thermal and electrical properties on the surfaces of ferritic stainless steel interconnects at high temperatures. [19][20][21][22] Mn-Co spinel coatings have been developed using various methods, including pack cementation, 23 physical vapor deposition, 24 electrodeposition, 25 plasma spraying, 26 magnetron sputtering, 27 and electrophoretic deposition. 28 Adding reactive element oxide particles like La 2 O 3 , ZrO 2 , and Y 2 O 3 to spinel coatings improves their adhesion to the substrate and enhances protective properties against oxidation at high temperatures.…”

The present study compared the performance of uncoated, Mn-Co and Mn-Co-CeO2-coated Crofer 22 APU ferritic stainless steel interconnects. The samples were oxidized for 500 h in an electric furnace at 800 °C. The surface morphology and phase structure of the samples before and after oxidation were examined using FESEM microscopy and X-ray diffraction (XRD) analysis, respectively. The electrical conductivity evaluation of the samples was also conducted by measuring the area specific resistance (ASR). The results indicated that the weight gain of the uncoated, Mn-Co and Mn-Co-CeO2-coated samples after 500 h of oxidation was 0.55, 0.58 and 0.27 mg.cm−2, respectively. Additionally, a comparison of the oxidation kinetics of the experimental samples revealed that the oxidation rate constant of the Mn-Co-CeO2-coated steel is 10 and 40 times lower than that of the Mn-Co-coated and uncoated steel, respectively. XRD analysis of the samples after oxidation confirmed the presence of MnCo2O4, Co3O4, and (Mn,Cr,Co)3O4 in the oxidized Mn-Co-coated, MnCo2O4, Co3O4, and CeO2 in the oxidized Mn-Co-CeO2-coated, and the chromium-containing phases (FeCr2O4, MnCr2O4, and Cr2O3) in the oxidized uncoated samples. The presence of phases with high electrical conductivity in the oxidized coated samples reduced their activation energy for conduction compared to the oxidized uncoated sample.

“…By optimization of deposition parameters and post-deposition air anneal, significant improvement in both Cr poisoning of the cathode and in ASR were observed in cells assembled with coated versus uncoated samples. 140 Large area filtered air deposition (LAFAD) and hybrid filtered arc deposition-assisted EBPVD (FAD-EBPVD) were utilized to deposit two-segment coatings with a Cr-Co-Al-O-N-based bottom segment and Mn 1.5 Co 1.5 O 4 top segment, respectively. 119 The Cr-Co-Al-O-Nbased bottom compound was applied to further improve the interconnect performance.…”

With the reduction of solid oxide fuel cell (SOFC) operating temperature to the range of 600 °C–800 °C, Cr-containing ferritic alloys have become the preferred interconnect material, which unfortunately are susceptible to continuous scale growth and Cr volatility at the SOFC operating temperatures. The (Mn,Co)3O4 spinel system is widely regarded as the most effective coating for SOFC interconnect protection, due to its high thermal and electrical conductivity, adequate coefficient of thermal expansion, and excellent Cr blocking capability. This article reviews the physical and chemical properties of the (Mn,Co)3O4-based spinels; different types of coating precursors and deposition techniques; and the effects of spinel composition, quality and thickness on the coating performance. It is concluded that the spinel coating composition, quality, and thickness are more critical than the coating process in affecting the overall coating performance.
