Cemented carbides are used for bearing parts as well as cutting tools, but their sliding ability is not sufficient for severe conditions. In order to improve their ability, an introduction of pores into cemented carbide was attempted by means of addition of spherical resin to the milled powder. The specimens were fabricated by conventional methods. Their microstructures, mechanical properties and dynamic coefficient of friction were investigated. The results obtained were as followes:<BR>(1) pores were homogeneously dispersed in specimens, and their shapes and dimensions corresponded to the added resins, (2) the hardness was decreased with the increase in pore content and transverse-rupture strength was decreased with the increase in pore content and their dimensions, and (3) the dynamic coefficient of friction between the pore dispersed cemented carbide and a conventional cemented carbide was smaller than that between conventional cemented carbides.
