Casting Component and Method for the Application of an Anticorrosive Layer

A casting component for a device for casting or handling a metal melt, the component comprising a metallic basic body and a melt contact surface region which is exposed to the metal melt during casting operation, wherein the metallic basic body is provided in the melt contact surface region with an anticorrosive layer which is resistant to the metal melt and which is formed, using at least one of microparticles or nanoparticles of one or more substances from a substance group which comprises borides, nitrides and carbides of the transition metals and their alloys and also boron and silicon and Al2O3.

A method for applying an anticorrosive layer to a substrate, the method comprising the steps of:

• performing a sol/gel process;
• and
• in performing the sol/gel process, using at least one of microparticles or nanoparticles with an average particle size of between 100 nm and 30 μm as a filler.
