In what is now the PDC are widely applied in the industrial society, mainly because of diamond compact has other materials incomparable superior performance. Today is for everybody to analyse the superior performance of PDC:
First diamond compact has high hardness and wear resistance (abrasion ratio). Hardness up to about 10 000 HV of PDC, is currently the world's most hard materials, artificial material than cemented carbide and high hardness of engineering ceramics. Due to the high hardness and isotropic, thus has excellent wear resistance. Usually by abrasion ratios reflect the wear resistance of composite sheet, in the middle of the 80 s ~ 90 s of the 20th century, compact abrasion ratio of 4 to 60000 (abroad for 8 ~ 120000); In the mid - 1990 - s to now, the abrasion of compound piece than for 8 ~ 300000 (10 ~ 500000) abroad.
