| 摘 要： | The bonding performance between synthetic diamond grit and adhesive (Co-Si alloy ) in polycrystalline dianond conpact (PDC) has been investigated.The results indicate that the carbide-forming element Si diffuses towards the diamond grit and the quantity of Si elenent in the inter layer of diamond grit-adhesives is about two timeshigher than that in the other area .New compound SiC exists in the inter layer of diamond-adhesives.The formation of SiC enhances the strength and prolongs the service life of PDC .The sintering time is important to the formation of SiC.

| Abstract: | The bonding performance between synthetic diamond grit and adhesive ( Co-Si alloy) in polycrystalline diamond compact ( PDC) has been investigated. The results indicate that the carbide-forming element Si diffuses towards the diamond grit and the quantity of Si element in the inter layer of diamond grit-adhesives is about two times higher than that in the other area. New compound SiC exists in the inter layer of diamond-adhesives. The formation of SiC enhances the strength and prolongs the service life of PDC. The sintering time is important to the formation of SiC. |
