Abstract
To electrolessly depositing nickel on tungsten surfaces or molybdenum surfaces which have been deposited on surfaces of ceramic bodies, the ceramic bodies are nucleated, preferably after thorough cleaning, for example with aqueous hydrofluoric acid, by immersion in an aqueous solution containing palladium ions and then introduced into an electroless nickel-plating bath. Before the nickel-plating, the nucleated ceramic bodies are treated in a bath containing a complexing agent for palladium ions, for example in an aqueous cyanide solution.
