Volume reduction mandrel for use in pneumatic isostatic forging |
摘要 |
A densified sintered product, such as a rolling cutter adapted for use in a steel tooth rolling cutter earth boring bit, has a layer of a metal powder applied to the external surface of the unsintered compact, the metal powder being melted to form a thin glaze of the melted metal powder on the external surface of the sintered compact, and the sintered compact may then be pneumatically isostatically forged.
