Publication number: 20220410261Abstract: The invention relates to a method of manufacturing a composite component (21) having a varying electric resistivity along a longitudinal direction of the component. At least a first paste (10a) having a first composition, and at least a second paste (10b) having a second composition are prepared. The pastes are transferred into a supply chamber (35) of a processing equipment (31), such as an extruder. A green body (20) is shaped by forcing the pastes from the supply chamber through a die (32), and the green body is then sintered or oxidized to form the composite component. The pastes may comprise metal powder, ceramic powder, and binder. The varying electric resistivity may be due to variations in one or more of the following parameters: the volume ratio between the metal powder and the ceramic powder, the size of the ceramic particles, and the type of the ceramic material.Type: ApplicationFiled: December 3, 2020Publication date: December 29, 2022Inventors: Flemming Buus Bendixen, Peter Valler, Alexandro Sorea, Henrik Rasmussen
