ABSTRACT:
A protective layer of a refractory material deposited on a metal electrode layer of an oxygen sensing element is improved by a process comprising forming the protective layer onto the surface of the metal electrode layer by plasma spray coating the surface of the metal electrode layer, first with a refractory material powder at a position of a prescribed distance from a plasma spray coating device and at a prescribed electric power, and second, with a refractory material powder having the same particle size and composition as said refractory material powder used in the first plasma spray coating at a position of a distance greater than said prescribed distance and/or at an electric power lower than said prescribed electric power.
