Popis:	PcBN–Al composites（PAC）have been synthesized by pressure infiltration(PI) and a general mixing method(GM)[1-3] with a wide grain sizes range of 4-25 um and a wide temperature range of 1200-1600°C at 5.0 GPa,respectively.Hardness ranged between 30and 40 GPa, while the flank wear (Vb) reached 0.12mm when it finished 4000m in cutting test ofPAC synthesized by PI method. Hardness ranged between 25 and 35GPa, while the flank wear (Vb) reached 0.14 mm when it finished 4000mof PAC synthesized by GM method. The homogeneity of PcBN–Al synthesized by PI have been improved compared with GM. PI is a superior method to synthesize PAC in the field of mechanical properties.
