His innovative approach has led to the development of a unique abrasive surfaced article that enhances the performance of superalloy gas turbine engine blades.
Latest Patents
James M. Goodman holds a patent for an "Abrasive surfaced article for high temperature service." This invention features a very thin abrasive material on a substrate, comprised of ceramic particulates contained within a metal matrix. The particulates extend fully through the matrix from the substrate surface to the machined free surface of the abrasive. In a representative 0.38 mm abrasive, the particulates are sized normally at 0.42-0.50 mm and have an aspect ratio of less than 1.9 to 1. This design enables a high density of particulates, in the range of 33-62 per cm², while ensuring good bonding as most of the particulates are fully surrounded by the matrix. When applied to the tip of a superalloy gas turbine engine blade, about 10-50% of the matrix metal is removed after machining. This allows the machined ceramic particulates to project into space, thereby better interacting with ceramic abradable seals. The preferred practice of this invention utilizes alumina-coated silicon carbide contained in a nickel superalloy matrix.
