“…Their work highlighted that the uniform and dense enamel layer could provide oxidation protectiveness to Ti60 titanium alloy at high temperatures, thus protecting the substrate from oxygen embrittlement for long-term oxidation. On the other hand, Tao et al 102 concentrated their studies on the ability of enamel coatings to counteract the passage of hydrogen ions by means of hydrogen charging tests and deuterium penetration experiments. Their results proved that enamel coating represented an effective barrier against hydrogen isotope penetration, thanks to the loss of shortcut of hydrogen diffusion and the formation of the bonds like the O-H and Si-H ones.…”

Vitreous enamels represent a class of coatings with different technological properties, mainly appreciated for the protection they guarantee to the covered substrates. This review introduces enamel coatings, describing their production technologies and presenting the main properties affecting the enamel’s durability. Firstly, this review article introduces the most important studies regarding the improvement in abrasion resistance, highlighting both successes and failures. Afterward, the work reveals an outlook about the resistance to chemicals, underlining the good resistance of enamels toward acidic chemicals and discussing the results of studies aimed to improve their performances toward alkaline solutions. This review also considers the corrosion protection property of enamels, highlighting the high barrier effect they provide against the absorption of aggressive substances toward metal substrates. Finally, new perspectives and possible future research paths are presented, being aware that this kind of coating offers both good product protection and functional integrity over time.

“…Fe is from the substrate at the edge of the sample. As titanium oxides were also demonstrated to be effective hydrogen penetration barriers, the presence of TiO 2 and Ti 2 O 3 will not have an unfavorable influence on the tritium permeability of the coating. Even though the laser scanning speed is as high as 60 mm/s, the reaction of the powders can be ignited and is carried out completely, leading to the formation of α‐Al 2 O 3 and TiC.…”

Well-crystallized a-Al 2 O 3 /TiC composite coating was synthesized on the surface of steel substrate by a facile laser-assisted combustion synthesis technique without subsequent calcination. The effect of laser cladding speed on formation and microstructure of the coatings was studied. At 6 mm/s, a-Al 2 O 3 /TiC coating with good quality was obtained without pores and cracks and was well bonded with the steel substrate. By adjusting the precoating thickness, the coating thickness was easily controlled. As a simple, environmentally friendly and energy-saving technique, laser-assisted combustion synthesis is expected to find applications in ceramic coating fabrication as tritium permeation barrier or wear-and corrosion-resistance coatings. ExperimentalSteel plates (AISI 1045 steel) were used as substrates. Before precoating, substrates (50 mm 9 50 mm 9 8 mm) were polished with waterproof abrasive paper *liheping@hust.edu.cn

“…As can be seenfrom the element distributions, adistinct diffusion layer was observeda tt he interface. This can be explained by the fact that,inthe process of plasma spraying, the sprayed powder was melted and the elements diffused into the substrate, while substrate materials were partially melted by the hyperthermal fusion of the sprayed powder and the elements diffused into the coating [17].The interfacial bonding strengtho ft he coating was effectively improved by the diffusion layer.

Regression analysis of bonding strength of sprayed coatings based on acoustic emission signalThe aim of this paperwas to obtain the regression equation of the bonding strengtho fs prayed coatings vs. acoustic emission (AE) signal. FeCrBSi coating, Al 2 O 3 -40 wt.% TiO 2 (AT40) coating and Al 2 O 3 coating were prepared using an atmospheric plasma spraying system.T he microstructures and properties of the coatings werecharacterized. The coatings exhibited typical laminate structure with low porosityand goodbonding interface. The AE signals during indentation testingw ere abstracted and investigated. AE energy was more sensitive to the coating cracking failure than AE amplitude. Moreover, the energy of AE burst signal had ac lose positive relationship with coating bonding strength.The distributioncharacteristic of AE peak energy was discussedb ased on the Weibull distribution. The best regressione quationsf or the three coatings wereo btained to predict the bonding strengths of sprayed coatings based on AE burst signal energy for similar coating/substrate systems.
