Abstract

A method for locally treating a plate is disclosed. A pattern formed from a compound containing at least one alloying element is applied onto at least one surface of the plate. At least the surface of a contacting layer including the pattern is covered by adequately heat-resistant material. The plate is subsequently heat treated in order to diffuse the alloying element into the plate.
