The most common ceramic coatings are alumina, titania, zirconia, alumina-magnesia, hafnia, silicon carbide, silicon nitride and boron carbide, as well as oxides of many of these materials. Methods such as detonation guns, oxygen-acetylene powder deposition, chemical vapour deposition and plasma spraying are typical methods used to apply ceramic coatings tosurfaces. It should be noted that hydrophobic treatment of ceramic coatings on metallic materials ensuring superhydrophobic surfaces with special surface physicochemistry has recently received much attention in many fields. This type of coating system is often available on the market as 1-component (1-K) products with a longer service life.
Ceramic coating protects a car's paintwork from stains and damage and keeps it cleaner for longer. The tough outer layer of a dry ceramic coating is chemically bonded to the metal substrate to form a passive, waterproof top layer. Ceramic coatings go further than conventional organic paints and coatings: their electrical and thermal insulation properties, corrosion resistance and low coefficient of friction make them highly versatile. Unlike traditional coatings, which contain up to 60 percent water, ceramic coatings contain a high percentage of solid microspheres.
Ceramic coatings, also commonly known as glass coatings, nano-coatings, silica coatings and hydrophobic coatings, are defined as an inorganic, non-metallic, semi-permanent, protective transparent coating that is applied to several different types of surfaces. Ceramic coatings are fast becoming a viable alternative to organic and polymer-based coatings for surface protection applications. Make sure that no contaminants, dirt or oily film is left on the car, as the ceramic coating will not be able to seal properly. Comparison of the properties of the unmodified ceramic coating and the superhydrophobic ceramic coating on metallic materials.
Preparing the Al2O3 ceramic coating on AZ31PH Mg alloy by laser remelting of the plasma spray coating, it was found that the Al2O3 ceramic coating exhibited high hardness, wear and corrosion resistance properties. This results in a ceramic coating with a higher crosslink density, producing ceramic coatings with a pencil hardness of up to 10H, such as IGL Coatings ecocoat KENZO. This chapter will focus on the types, manufacturing methods, surface properties and applications of ceramic coated metallic materials. This allows ceramic coatings to be used in situations that are simply not suitable for conventional paints.
