摘要

For evaluating and control the quality of impregnated diamond bit used in exploration drilling and improving the microstructure of the final matrix layers to equivalent its working life with the initiative， layers etc， the proper-ty of load applied on bit crown and the KI， value and the regulating of the Kk， value as well have been discussed and tested。 The results shows that the diamond bit quality can only be correctly and precisively judged by using experi-mentally measured physical-mechanical properties and K1， value， controlling the cracking speed and reinforcing the final matrix layers with W fibres can equivalent the service life of the final matrix layers significantly。
