摘要：A method of repairing stator blades in a turbine comprises the steps of makinga pre-shaped insert (20) of a material the same as or compatible with the material of thestator blade (12), the size of the insert is such that it forms a substantial part of thestator blade, the method including the step of removing a piece of material from thestator blade including the damaged part or part that it is required to modify and weldingin the new insert. The insert is treated so that at least a part of it is hardened, thehardening may be diffusion alloying or plasma spray and the size of the insert is that theweld line between the insert and the turbine blade is removed from the area of high wearby making the insert larger than would apparently appear necessary, this enablessubstantial cut-outs to be made on each stator blade which in turn permits of muchbetter access to the stator blades for securing the new insert and/or additionalhardening steps such as plasma spray after the insert has been secured to the statorblade.
