“…38 Although the Guglielmi model has been confirmed by various researchers, [39][40][41][42][43] neglecting mass transfer and the size of ions and reinforcing particles have been highlighted as one of the main drawbacks of this model. 44 The XRD analysis result of the Mn-Co and Mn-Co-CeO 2 coatings are presented in Figs. 2a and 2b, respectively.…”

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.

“…Switching to ionic liquids to overcome such drawbacks has gained significant attention (Maniam and Paul, 2020). The electrodeposition of composite coatings containing particles in a metal matrix is reviewed by (Walsh and Larson, 2020). Key challenges they conclude are i) understanding the interactions among bath composition, operational conditions and deposit properties and ii) limitations in models describing composite electrodeposition.…”

The subject areas of Coatings, Dyes and Interface Engineering are rarely seen together although there is potentially a huge synergy from embracing coatings-dyes-interface interactions. This allows an enabling science that aligns with global grand challenges such as net zero (batteries, renewal energy systems, low drag, antifouling and low friction interfaces, self-healing coatings, functionally graded, composite and multi-layered coatings sustainability of coatings, etc.), biomedical/health technologies, space and security. Coatings, dyes and interfaces engineering are used to optimize the functionality and to improve the entire function of materials and surfaces. Coatings have a wide range of forms, such as paints, adhesives, semiconductor thin films, hard facings and have a varied application route such as mechanical systems, solar cells, domestic appliances, photonics, smart coatings, microelectronics, offshore renewables, biomedical and photographic films. Several application and synthesis methods, such as sol-gel, spin, dip, physical and chemical vapour deposition, thermal spray, weld overlays, plasma electrolytic oxidation, atomic layer deposition, electroplating and so on, have been used for thin or thick hard and soft coatings and films.This article looks at recent state-of-the-art and related special issues and review papers to identify trends and future challenges for research in these areas. In scope for embracing coatings-dyesinterface interactions are thin and thick, composite, hard and soft coatings, coating structure and properties, processes for coating deposition, modification and characterization techniques, functional, smart, self-healing and sensing coatings, dyes, pigments and their intermediates. These in turn rely on fundamental mechanical and chemical as well as functional properties of surfaces and interfaces, theoretical and computational modelling of surfaces and interfaces as well as colloids, nanoparticles and large interfaces. The key to improved performance of coatings-dyesinterface engineering is understanding the manufacturer-composition-properties-performance interactions aligned to the service environment and operating conditions. Such research will be essential for energy research, photovoltaics, battery and electrochemical surfaces, biomedical applications, electronic applications of dyes and pigments, low friction, efficient machines and low drag, hydrophobic and nature inspired coatings. However, new understanding is needed for dynamic interfaces covering wear, corrosion, erosion for example. Modern measurement and imaging systems now allow in-situ and non-destructive monitoring of these interfaces. Miniaturisation of sensors and embedding sensors alongside or within interfaces is now possible which should provide a digital data stream for machine learning algorithms to allow smart interface management. Therefore, the challenges now lie around the synthesis and characterization of thin films and multifunctional coatings and the use of novel interface characterization techniq...

Traditionally, electroplating has involved the continuous deposition of a single layer of metal at constant current. However, electrodeposition of alternate layers can offer benefits such as reduced wear, improved corrosion resistance and higher tensile strength. The alternate layers can involve different morphology or thickness of metal, different metals or the alloy composition of layers with and without included particles. In the case of a single bath, electrocrystallisation is continuous but layers can be tailored to have different chemical composition, phase composition, morphology and microstructure. The composition of layers can also be systematically modified in a gradient fashion. The thickness of each metal layer can vary from >20 m down to ≈ 1 nm; in the case of nanometre thick layers, up to 500 layers of 1 nm thick individual layers might be involved. Compact multilayer deposition from a single bath is often achieved by applying a potential waveform in the laboratory or pulsed current in industry. While multilayer electrodeposition is going through a phase of rediscovery, growth and diversification, the field can be traced back to a patent involving Cu-Ni multilayers, in 1905. Progress in multi-layered electrodeposition has made use of contemporary trends in electroplating research, including self-assembled layers, nanowire arrays and the use of deep eutectic solvents for electrolytes. The developing uses of multilayer deposits are seen to span industries as diverse as wear and corrosion resistant coatings, toolbits and heavy engineering. Speciality uses include electronic, optical and magnetic materials as well as catalytic electrode surfaces for electrochemical technology. Recommendations are made on aspects which deserve further R & D.
