Abstract
A composite molding compound comprising a combination of metal and ceramic powders is disclosed. The powders are combined with a binder, a liquid carrier and other processing additives in a manner to provide uniform distribution of two phases in a material format that facilitates the molding of complex parts at relatively low pressures and temperatures using conventional injection molding machines. The products formed from these molding compounds may be designed with tailored physical and mechanical properties such as thermal conductivity, thermal expansion coefficient, density, elastic modulus and wear properties.
Claims12
A method for producing a homogeneous composite molding compound comprising the steps of:
- a) mixing a metal powder with water and a gel-forming material selected from the group of polysaccharides consisting of agaroids;
- b) mixing a ceramic powder with water and a dispersant, and ball milling the mixture to reduce the particle size thereof;
- c) compounding the metal powder mixture and the ceramic powder mixture;
- and
- d) shredding the compound mixture into a particulate format.
