Ceramic mould and method of producing same.

摘要

A ceramic mould (10) for use in the production of powder metallurgy articles (22); the mould (10) has a ceramic body (12) with a mould cavity (14) therein conforming substantially to the configuration of the article (22) to be produced. The mould cavity (14) is adapted to be filled with powdered metal (20) which is then compacted to form the article (22). The improvement of the invention is the mould cavity (14) having a continuous metal coating (18) covering the entire surface thereof so that the powdered metal (20) prior to and during compaction does not come into contact with and be contaminated by the ceramic of the mould body (12).
