A method for preparing a thermal barrier coating (TBC) material includes: spraying a metal mixture onto a surface of an alloy using supersonic flame spraying or explosive spraying to form a bottom layer; spraying an yttria-stabilized zirconia (YSZ) precursor sol onto the bottom layer using liquid plasma spraying to form an intermediate layer; and spraying a ceramic composite including SiO.sub.2 and La—Ce—Zr—O using plasma spraying or explosive spraying to form a surface layer.

A covering device (10) for covering at least one region (21) of a component (20) during a high-temperature coating process, the covering device (10) being placed essentially form-fittingly on the component (20) during the high-temperature coating process to prevent the at least one region covered by the covering device from being coated. The elements of the covering device (10) placed essentially form-fittingly on the component (20) are fabricated of a high temperature-resistant plastic which is dimensionally stable during the high-temperature coating process.

Various embodiments include a method for producing a least one conductive track comprising: forming a surface with a thermoplastic; and depositing conductive track material on the surface by thermal spraying.

A component for exposure to a combustion chamber of a diesel engine and/or exhaust gas, such as a cylinder liner or valve face, is provided. The component includes a thermal barrier coating applied to a body portion formed of steel. A layer of a metal bond material can be applied first, followed by a mixture of the metal bond material and a ceramic material, optionally followed by a layer of the ceramic material. The ceramic material preferably includes at least one of ceria, ceria stabilized zirconia, yttria stabilized zirconia, calcia stabilized zirconia, magnesia stabilized zirconia, and zirconia stabilized by another oxide.

An yttrium fluoride sprayed coating having a thickness of 10-500 m, an oxygen concentration of 1-6 wt %, and a hardness of 350-470 HV is deposited on a substrate surface. The yttrium fluoride sprayed coating exhibits excellent corrosion resistance in a halogen-base gas atmosphere or halogen-base gas plasma atmosphere, functions to protect the substrate from damage by acid penetration during acid cleaning, and minimizes particle generation from a reaction product and due to spall-off from the coating.
