Heat protective coating used on exhaust gas manifolds, pre-pipes and catalyst in vehicle engines consists of a ceramic material containing titanium

摘要

Heat protective coating consists of a ceramic material containing titanium. An independent claim is also included for a component giving off heat radiation comprising an adhesion promoting layer, especially a metal oxide, arranged between the structural body of the component and the heat protective coating. Preferred Features: The ceramic material contains yttrium and a pyrochlore structure is formed in the material. The ceramic material comprises 45.5 mole TiO2/54.5 mole Y2O3 or 55 mole TiO2/45 mole Y2O3. The material has a layer thickness with which the transmission is less than 0.1, preferably 0.
