Abstract
A method of modifying a coupling geometry in a shroud band segment of a turbine moving blade includes the following steps: calculation of a modified coupling geometry; removal of shroud band material situated outside the modified coupling geometry; and/or application of additional material not present inside the modified coupling geometry; reworking the removal and/or application zones. The method avoids disadvantages of the prior art and provides improved wear behavior in the coupling region so as to prolong the life of the turbine blades in an effective and inexpensive manner.
