FIELD: laminated products or materials.
SUBSTANCE: invention relates to substrate ceramic laminates, the functional layer of which is ceramic, and concerns a part with a functional surface and its application. Part with a functional includes a substrate and a polycrystalline functional layer, wherein said functional layer includes said functional surface. Substrate and functional layer are connected to each other through an adhesion promoter. Functional layer includes a transparent ceramic, which contains Al-Mg-spinel-, Al2O3-, AlON-, SiAION-ceramic, ZrO2 or a mixed oxide ceramic from the Y-Al-Mg-O system, and the ceramic may contain up to 5 wt. % of alloying elements.
EFFECT: invention provides for the creation of parts with a mechanically, chemically or thermally stable functional surface.
