The removal of a metal or alloy from the surface of a body, in particular turbine blades, by forming close to as in contact with the surface a one or more other metal or metals which will alloy with the metal or alloy to be removed. By forming the one or more other metals in situ, for example by electrolytic methods, attack of the underlying surface such as occurs when removal is effected by dipping the body in a bath of molten metal, is avoided.
