Title: Innovations by Louis Patrick Earvolino
Introduction
Louis Patrick Earvolino is a notable inventor based in Holliston, MA (US). He has made significant contributions to the field of engineering, particularly in the repair of steam turbine rotors. With a total of 3 patents to his name, Earvolino's work showcases his expertise and innovative approach to solving complex engineering challenges.
Latest Patents
Earvolino's latest patents focus on methods for repairing steam turbine rotors. One of his key inventions is 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 both the rim portion and the dovetail region. The method is particularly designed for steel alloy rotors, such as NiCrMoV, NiMoV, and CrMoV alloys. The weld repair is created using a nickel-base superalloy that possesses mechanical and thermal properties compatible with the repair method and the steel alloy over a broad temperature range.
Another patent by Earvolino describes a turbine rotor that includes a radially-inward portion made of steel alloy and a radially-outward rim portion. This rim portion is formed by a weldment that incorporates a nickel-base superalloy region, which joins the rim portion to the inward portion of the turbine rotor. The nickel-base superalloy is engineered to have a room temperature ultimate tensile strength of at least about 690 MPa.
