| 简介 |
The invention involves the fields of ceramics and surface technology and relates to a non-oxidic ceramic coating powder that can, for example, be used for producing layers using methods taken from the thermal spraying process group. The aim of the invention is to provide a non-oxidic ceramic coating powder, which can be processed into layers by using the current methods of the thermal spraying method group (variants of plasma spraying, detonation spraying, high-velocity flame spraying (HVOF)), and to provide layers produced therefrom. To this end, a non-oxidic ceramic coating powder containing, as a main constituent, a carbide or mixtures and/or compounds of carbides and containing, as secondary constituents, compounds comprised of aluminum oxides and of rare-earth oxides. In addition, a non-oxidic ceramic layer is provided in which carbides or mixtures and/or compounds of carbides are sintered with essentially crystalline aluminum rare-earth oxide compounds serving as secondary phases. |
