文摘

The compressibility of the WC/Co is essential for the compressibility of the resulting cemented carbide granule. The compressibility of the cobalt powder can be increased by varying the powder characteristics. A longer milling time caused a change in the compressibility of the Co powder Excessive oxygen absorption of the cobalt powder deteriorates its compressibility.
