Latest Patents
One of Woodhouse's notable inventions is the "Process for forming unusually strong joints between metals and ceramics." This process allows for the joining of nodular cast iron to partially stabilized zirconia using a low brazing temperature of less than 750°C. The method involves coating the ceramic with an active metal like titanium, which can form intermetallic compounds with a low melting point brazing alloy. Additionally, the nodular cast iron is treated with a non-carbon-containing metal, such as copper, to prevent carbon dissolution during the brazing process. This innovative technique leads to the creation of exceptionally strong joints, especially when a transition piece compatible with the ceramic's thermal expansion is used.
Another significant patent by Woodhouse is the "Assembly for testing weldability of sheet metal." This assembly is designed to determine the weldability of sheet metal effectively. It comprises a base with a flat side surface featuring an annular groove, a test disk positioned within a counterbore, and a clamp ring that secures the disk against the base. The design ensures accurate testing of weldability, providing critical insights for manufacturing processes.
