Abstract: A high temperature article, for example an igniter for a combustor is presented. The igniter includes a central electrode having a discharge end, an insulator sleeve surrounding the central electrode and a tubular electrode shell surrounding the insulator sleeve. The tubular electrode shell has a forward end projecting beyond the discharge end. The tubular electrode shell includes an iron-based alloy. The igniter further includes a protective coating including alumina disposed on a surface of the forward end. A combustor of a turbine engine, including the igniter is also presented.
