Abstract
A method for bonding silicon-containing compositions to metal surfaces is disclosed wherein a coarse silicon-containing surface is arc-sprayed with a first adhesive layer, a second solderable layer, and a third solder layer, and the arc-sprayed surface is then soldered to the metal surface. The method is particularly useful for producing silicon-containing targets for cathode sputtering.
