Abstract

A spark plug electrode with an electrode tip formed on an electrode base using an additive manufacturing process, such as a powder bed fusion technique. The spark plug electrode includes an electrode base, an electrode tip that is formed on the electrode base and includes a precious metal-based material, and a thermally resilient joint that is located between the electrode base and the electrode tip, wherein the electrode tip and the thermally resilient joint together include a number of laser deposition layers.
