Abstract

A method of constructing a fully dense metal part or a metal mold half for mating with another mold half to form a mold for casting multiple parts. Steps include placing a pattern in a tubular mold base, casting a ceramic member onto critical surfaces of the pattern, removing the pattern from the mold base, covering the critical surfaces transferred to the ceramic member with a powdered metal (24) having a melting temperature greater than that of an infiltration metal (26), placing a quantity of an infiltration metal (26) over the powdered metal (24),placing the tubular mold base (10) in a furnace at a temperature sufficient to melt the infiltration metal without melting the powdered metal, and removing the ceramic member (20) from the first open end of the tubular mold base to expose the critical surfaces. The quantity of the infiltration metal is sufficient to fill voids between the particles of the powdered metal when the infiltration metal is melted, thereby generating a fully dense metal part. The metal part has the critical surfaces transferred from the ceramic member when the infiltration metal solidifies. The metal powder also acts as a filter to filter out any contamination or oxidized metal within the infiltration metal so that such contamination does not blemish the finished surface of the fully dense metal part.
