Cathode poisoning by chromium evaporation from the interconnects is one of major degradation mechanisms in SOFC. Coatings have proved to be very effective suppressing on interconnects. The quantification important for determining consumption interconnect and predicting lifetime interconnect. Chromium uncoated Ce/Co coated Crofer 22 APU reevaluated at 800°C. coatings steel sheets precut steels s...

In this investigation PVD Ti-Cr)N coatings were deposited on hardened and tempered tool steel substrates using reactive arc evaporation. Physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and modulus young and coefficient friction were evaluated. Phase compositions were studies by X-ray diffraction method. The surface microstructure and morp...

Abstract To prevent volcanic ash corrosion using thermal barrier coatings (TBCs), a novel method Al 2 O 3 -modification was proposed to reduce molten CMAS wettability on TBCs surface through lotus effect. Plasma spray-physical vapor deposition (PS-PVD), third-generation for fabrication, adopted deposit 7YSZ with feather-like microstructure. Then, modification introduced fabricate dense overlay ...

Hard and wear-resistant coatings created utilizing physical vapor deposition (PVD) techniques are extensively used in extreme tribological applications. The friction wear behavior of vary significantly with temperature, indicating that advanced coating concepts essential for prolonged load-bearing Many have recently been explored this area, including multicomponent, multilayer, gradient coating...
