Coated metallic component

摘要

The coated metallic component (1) comprises a material composition for a turbine component, which is produced form a metallic base material (3), where the material composition comprises a matrix material with glass-ceramic basic properties for forming base matrix of a coating (5), and a filler material for adjusting desired coating properties and/or coating characteristics. The matrix material and/or the filling material comprises nanoparticles having particle size smaller than 1 mu m. The filling material comprises color pigments of pigment types, a mixture of different types of pigment. The coated metallic component (1) comprises a material composition for a turbine component, which is produced form a metallic base material (3), where the material composition comprises a matrix material with glass-ceramic basic properties for forming base matrix of a coating (5), and a filler material for adjusting desired coating properties and/or coating characteristics. The matrix material and/or the filling material comprises nanoparticles having particle size smaller than 1 mu m. The filling material comprises color pigments of pigment types, a mixture of different types of pigment, metal- or metal alloy particles, hard material particles, temperature-resistant particles, and dry lubricants as nanoparticles. The coating comprises two layers, which contain different types of pigment. The particle size of the nanoparticles is in the range of 50-200 nm. A solid component of the matrix materials is formed as the nanoparticle. The metal and/or the metal alloy of the metal alloy particles are selected in such a way that a sacrificial anode effect is implemented. The metal- or the metal alloy particles are deactivated, and comprise an oxide layer for deactivating, a phosphate layer or a deactivation layer compatible to the base matrix and/or other filling materials.
