Abstract

The method is for preparing a specimen for spectrographic analysis. It avoids the time-consuming sample preparation normally required while avoiding the base material spectrum that interferes with the coating spectrum when analyzing a coating on the base material. This is accomplished by coating a substrate that does not present an interfering spectrum. The process involves preparing a spectrographic graphite electrode for plating, which for electroless plating includes catalyzing the electrode with solutions of stannous chloride and palladium chloride. The electrodes are then plated with the desired metal coating, inserted into a spectrograph and excited to give the coating spectrum.
