Abstract (en)

[origin: GB2320034A] A coating consisting of ceramo-metallic material, e.g. WC-Co, is applied to an internal surface of a grid plate by flame spraying. A ceramic slurry is applied and fired to produce a ceramic coating which is partially removed to produce a composite ceramo-metallic and ceramic surface which is then bonded and densified. The coating is in the form of an array of islands. A ceramic slurry may then be applied and fixed to produce a ceramic coating which is partially removed to produce a composite ceramic-metallic and ceramic surface which is then bonded and densified. The ceramic slurry may contain a chromium compound capable of being converted into chromium oxide at temperatures of at least 300{C. The composite surface may then be impregnated with a solution of at least one soluble compound capable of being converted on heating, into an insoluble substance which bonds the coatings. The soluble compound may be selected from chromia and phosphate forming compounds.
