Latest Patents
Van Ullen's latest patents focus on methods for repairing steam turbine rotors. One patent describes a method for repairing the rim of a steam turbine rotor. This method involves removing a damaged rim and its associated dovetail region to create a surface at the perimeter of the rim portion. A weld repair region is then formed on this surface, which is machined to reconstruct the rim and dovetail region exclusively with the weld repair material. The method is particularly designed for steel alloy rotors, such as NiCrMoV, NiMoV, and CrMoV alloys. The weld repair is formed using a nickel-base superalloy that possesses mechanical and thermal properties compatible with both the repair method and the steel alloy over a broad temperature range.
Another patent details a turbine rotor that comprises a radially-inward portion made of steel alloy and a radially-outward rim portion. This rim portion is formed by a weldment that includes a nickel-base superalloy region, which joins the rim to the inward portion of the turbine rotor. The nickel-base superalloy is characterized by a room temperature ultimate tensile strength of at least about 690 MPa.
