Abstract
Metal-coated zirconia articles have at least one surface that is a surface-treated surface. The surface-treated surface is a phosphate-treated surface. At least a portion of the surface-treated surface is covered with a layer of metal. The metal covering adheres more strongly to the surface-treated surface than to an identical surface that is not surface-treated.
Claims16
An electrode, comprising:
- a zirconia-containing article comprising:
- at least one major surface comprising a phosphate surface-treated surface, wherein the phosphate surface-treated surface is formed by a phosphate salt solution;
- at least one non-porous ceramic particle having a compression strength greater than 400 megapascals and comprising at least one shaped zirconia-containing particle;
- and
- a layer of metal covering at least a portion of the phosphate surface-treated surface, wherein the layer of metal covering adheres more strongly to the phosphate surface-treated surface than to an untreated surface.

A method of preparing an electrode, the method comprising:
- providing a zirconia-containing article comprising:
- at least one major surface;
- at least one non-porous ceramic particle having a compression strength greater than 400 megapascals and comprising at least one shaped zirconia-containing particle;
- surface treating at least a portion of the at least one major surface of the zirconia-containing article with a phosphate salt solution to generate a phosphate-treated surface;
- and
- disposing a layer of metal on at least a portion of the phosphate-treated surface.
