PROBLEM TO BE SOLVED: To provide modification processes for an increased stress area in a turbine component and modified turbine components.SOLUTION: A modification process includes locating an area in an article 120, removing the area by machining to form a machined region 130, inserting a modification material into the machined region 140, securing the modification material to the article 150, machining the modification material flush with a geometry of the article 160, and applying a coating over at least a portion of the article 180. Another modification process includes locating an area under a suction side leading edge tip shroud fillet of an airfoil, removing the area by machining to form a hole, inserting a modification material having improved material properties into the hole, securing the modification material in place, machining the modification material and the airfoil to form a new fillet contour, and applying a coating over at least a portion of the airfoil. |
