The present paper describes the sintering characteristics of functionally gradient material (hereafter f.g.m.), such as aluminum nitride/HSS and zirconia/Ni, in order to clarify the influences of sintering conditions to the physical and mechanical properties of these compounds, and their applications to a kind of tool materials. It is clarified that both AIN and ZrO_2 compounds that were successfully fabricated by SPS, provide the moderate physical and mechanical properties. Micro Vickers hardness of AIN/10wt%HSS compound is larger than that of AIN compound. The hardness of ZrO_2/Ni compound is smaller than that of ZrO_2 compound due to the softness of Ni. The surface roughness of aluminum alloy cut by both AIN/HSS and ZrO_2/Ni f.g.ms. is slightly smaller than that cut by P20 in wet and dry cutting. The forces in cutting by AIN/HSS f.g.m are smaller than those in cutting by P20 and ZrO_2/Ni f.g.m. The flank wear of P20 is less than that of both AIN/HSS and ZrO_2/Ni f.g.ms. due to a larger hardness of tungsten carbide. However, the wear rates of P20 are larger than those of functionally gradient materials.
