A temporary cosmetic dental coating has a transparent resin matrix containing embedded glass microspheres. The refractive index of the microspheres is at least 0.03 greater than the refractive index of the transparent resin matrix. Incoming light is reflected back in the same direction as it was emanated, providing a lustrous dental coating that is cosmetically appealing and covers dental defects and discoloration. The transparent resin matrix with glass microspheres is formed by mixing together a methacrylate based liquid monomer of methyl methacrylate or BIS-GMA and glass microspheres coated with activators/catalysts. The user applies the mixed composition to the teeth to form a temporary cosmetic dental coating, which is readily removed using a dental pick. A lac resin dissolved in ethyl alcohol is optionally mixed with glass microspheres and applied to teeth surfaces. The coating is hardened by alcohol evaporation and removed by alcohol dissolution.

A ceramic thermal barrier coating (8) for coating the surface (7) of a component (1) of a nickel-based superalloy, and an adhesive coating optionally applied thereon (6), preferably a gas turbine component, includes zirconium oxide (ZrO₂) stabilized by yttrium oxide (Y₂O₃) and production-related impurities, as well as at least one high-temperature and oxidation resistant intermetallic compound, for example NiAl, YRh, ErIr, the volume fraction of which decreases continuously or in stages as the distance from the surface (7) of the component (1)/the adhesive coating (6) increases. Advantageously, a less steep stress gradient is produced by gradually varying the composition of the thermal barrier coating (8). This leads to an increased expansion tolerance of the thermal barrier coating (8) and thus, on the one hand, to an increased lifetime under thermal loading (no flaking) and, on the other hand, the possibility of applying thicker thermal barrier coatings (8), and therefore of using the coated components (1) at higher temperatures.
