  • Full ceramic bearings made from silicon nitride - SMB

    Several techniques have been developed for the encapsulation, and subsequent hotisostatic pressing (HIPing), of silicon nitride (Si3N4) based ceramics. Green-state and densified billets of silicon nitride were vacuum encapsulated in either glass tube or powder. Glass powder encapsulation allows complex shaped ceramic pieces to be HIPed. A selection of silicon nitride compositions were HIPed to ...
