Abstract
A spark plug may include a first electrode, an insulator positioned radially outside the first electrode, and a housing positioned radially outside the insulator. The spark plug may also include a second electrode electrically coupled to the housing. The second electrode may form a spark gap with the first electrode. The spark plug may further include an ignition electrode coupled to at least one of the first electrode and the second electrode. The ignition electrode may include fibers of Nb—Ti within a matrix material.
