ABSTRACT:
A process for pneumatically isostatically compacting a sintered compact to densify the compact wherein the surface of the compact is oxidized to form a gas impervious oxide barrier on said surface before the compact is subjected to the pneumatic isostatic compaction process. Oxidation of the compact surface is preferably accomplished by steaming the compact before or after sintering.
