“…Micro-arc oxidation (MAO) has been used as a critical method for many years to prepare much thicker and harder ceramic coatings on metallic materials. [33]. In addition, the porous Cu-TiO 2 coatings can be fabricated on titanium through MAO process under the constant current density of 20 A/dm 2 for 5 min, and the high stability TiO 2 coating formed during MAO process improved the corrosion resistance of titanium [43].…”

Surface coating can allow the bulk materials to remain unchanged, while the surface functionality is engineered to afford a more wanted characteristic. Ceramic coatings are considered as ideal coatings on metal which can significantly improve the surface properties of metal materials including anti-fouling, self-cleaning, corrosion resistance, wear resistance, oil/water separation and biocompatibility. Furthermore, various techniques have been utilized to fabricate a range of different ceramic coatings with more desirable properties on metal materials, which make the materials widely used in service environment. This chapter focus will be on the types, fabrication methods, surface properties and applications of ceramics coated metal materials.

“…It is well known that cermet coatings have high hardness. In industries among all the cermet coatings, tungsten carbides, nickel, chromium and titanium based coatings are widely utilised for their high erosivecorrosive wear resistance [6][7][8][9]. A huge number of research studies have been conducted by the researchers by utilising the tungsten based and nickel based coatings to enhance the erosive wear properties [10][11][12][13].…”

WC-12%Co, Cr 3 C 2 -25%NiCr, 80%Ni-20%Cr, 87%Al 2 O 3 -13%TiO 2 coatings were deposited by Air Plasma Spray (APS) technique on ASTM A36 steel. Erosion behaviour of sprayed coated samples were investigated at three different impact angles (45°, 60°and 90°). The mechanism of erosion was investigated on uncoated and coated samples. The rate of erosion of the substrate first increased with increasing angle of impact and then gradually decreased. But the erosion rate of the coated samples increased steadily. Substrate shows the higher metal removal whereas coating shows the higher erosion resistance. WC-12%Co coated samples performed well in erosion testing and offered best erosion resistance as compared to the substrate and all other coatings. Ductile fracture takes place on substrate material at higher impact angle. Overall, all the coated samples have shown less erosion propensity when compare to the bare one.

“…The MAO method can be used to form a ceramic coating with TiO 2 as the main component by in-situ oxidation on the titanium alloy. In the MAO process, the composite coatings such as TiO 2 + SiO 2 , TiO 2 + Al 2 O 3 , TiO 2 + ZrO 2 , TiO 2 + MoS 2 , TiO 2 + Ag, and TiO 2 + graphite can be formed on the titanium alloy substrate to improve the wear resistance, friction, and oxidation resistance of the titanium alloy by the regulation of the electrolyte composition and addition of solid particles in the electrolyte [14][15][16]. Compared with other surface technologies, the MAO exhibits strong adaptability, simple operation, and low cost, and is environmentally friendly.…”

A composite coating composed of intermetallic compounds, Al–Si alloys, and an oxide ceramic layer was prepared on TA2 substrate by hot-dipping Al–Si alloy and micro-arc oxidation (MAO) methods. The microstructure and composition distribution of the resulting hot-dipped Al–Si alloy layer and MAO-caused ceramic layer were studied by scanning electron microscope (SEM) and energy dispersive spectrum (EDS). In addition, the phase composition of the diffusion layer obtained by the Al–Si alloy hot-dipping procedure was investigated by electron backscattered diffraction (EBSD), and the phase structure of the MAO-treated layer was studied by X-ray diffraction (XRD) analysis and X-ray photoelectron spectroscopy (XPS). The MAO method can make the hot-dipped Al–Si alloy layer in-situ oxidized to form a ceramic layer. Finally, a three-layer composite coating composed of a diffusion layer formed by the Ti–Al–Si interdiffusion, an Al–Si alloy layer and a ceramic layer was prepared on TA2 substrate. Compared with TA2 substrate, the TA2 sample with a three-layer composite coating has larger friction coefficient and less abrasion loss. The three-layer composite coating can significantly improve the wear resistance of TA2. A technical composite method was developed to the low cost in-situ growth of alumina-based ceramic wear-resistant coatings on TA2 substrate.
