| Abstract: | The impact resistance of polycrystalline diamond composite(PDC) was tested with dropping hammer type PDC impacting work measurement device.The impact failure mechanism of PDC was discussed,the influence of the joint structure at the interface as well as particle size of diamond were discussed in the paper.The results showed that,the dropping hammer method was close to the actual stress conditions on the drill bit.Under the same technological conditions,the interfacial joint structure of the PDC layer and WC... |
