The ROC Process
ROCTEC® 复合硬质合金是一种碳化钨基材料,采用获得专利的快速全向压制 (ROC) 工艺制成,只有 Kennametal 获得许可使用这种工艺生产这些产品。
This process enables these advanced ceramic materials to be combined without using a soft metal binder and with very short consolidation cycles - minimizing the natural tendency of ceramic particles to enlarge when exposed to high heat for long periods.
Maintaining extra-fine grain size means better nozzle performance resulting in an extremely durable material that fiercely resists abrasive and erosive wear.
