Production of composite ceramic-metal materials comprises partially filling mold with ceramic or graphite, heating this near melting point of metal. Pouring molten metal in and evacuating chamber containing mold to remove gas bubbles

摘要

Production of composite ceramic/metal materials comprises filling a mold (1) 60 -95% full with a ceramic material or graphite. The material is heated to a maximum of 90% of the melting point of the metal and molten metal is then poured in. The mold is placed in a sealed chamber which is then evacuated, so that the production of gas bubbles (6) in the melt (4) is controlled. Evacuation is stopped when no more bubbles are produced.
