Infiltrieren

Infiltrated metal composites consist of two material components. During a two-stage manufacturing process, a porous sintered base is first produced from the component with the higher melting point, for example a refractory metal, before the open pores are then infiltrated with the liquefied component with the lower melting point. The properties of the individual components remain unchanged. When inspected under the microscope, the properties of each of the components continue to be evident. At the macroscopic level, however, the properties of the individual components are combined. For example, the new material may contain modified thermal conductivity and thermal expansion values.
