CEMENTED CARBIDE WITH BINDER PHASE ENRICHED SURFACE ZONE |
摘要 |
2130544 9317140 PCTABS00025 The present invention relates to a cemented carbide insert with improved toughness and resistance against plastic deformation containing WC and cubic phases of carbide and/or carbonitride in a binder phase based on Co and/or Ni with a binder phase enriched surface zone. The binder phase content in the insert is 3.5-12 weight-%. In a zone below the binder phase enriched surface zone the binder phase content is 0.85-1 of the content in the inner portion of the insert and the content of cubic phases essentially constant and equal to the content in the inner portion of the insert. |
