Title: Gerhard Mend: Inventor in Bearing-Steel Heat Treatment
Introduction
Gerhard Mend is an inventor associated with Schweinfurt, Germany, and SKF GmbH. His patent describes a process for case-hardening rolling bearing elements made from low-alloy nickeliferous steel.
Latest Patents
Mend is credited with 1 patent: “Process for Case-Hardening Rolling Bearing Elements of Low-Alloy Nickeliferous Steel.” The process carburizes the bearing elements in a dissociating gas, then cools them in agitated inert gas to about 300°C and holds them there. This allows dissociated hydrogen to escape from the carburized layer, helping prevent brittleness. The elements are subsequently heated to hardening or intermediate-annealing temperature and, when hardened, quenched.
Career Highlights
Mend’s documented patent work focuses on improving the heat treatment of rolling bearing components. The method addresses hydrogen-related brittleness during carburization by adding a controlled cooling and holding stage.
Collaborations
Mend is associated with SKF GmbH. Roger Bjorn and Frank Hengerer are identified as coworkers.
Conclusion
Gerhard Mend’s patent presents a targeted approach to reducing brittleness in case-hardened bearing elements by allowing hydrogen to escape before subsequent heat treatment.
