Title: The Innovations of Robert L. Greene
Introduction
Robert L. Greene is an accomplished inventor based in Ann Arbor, Michigan. He holds three patents, showcasing his contributions to the field of engineering and materials science. His work primarily focuses on developing advanced bearing materials that enhance performance and sustainability.
Latest Patents
One of Greene's notable inventions is a lead-free bearing. This innovative bearing consists of a bronze matrix powder metal bearing layer that is bonded to a fully densified steel backing. The material composition includes approximately 8 to 12% by weight tin, 1 to less than 5% by weight bismuth, and 0.03 to 0.08% by weight phosphorus, with the remainder being copper. The tin is soluble in the copper, forming the bronze matrix, while the bismuth is present as finely dispersed, undissolved islands throughout the matrix. These lead-free bearings exhibit physical properties that are comparable to or even better than traditional bronze-lead bearings, along with improved wear resistance in seizure conditions.
