From: Synthesis and Multi Scale Tribological Behavior of WC-Co/Nanodiamond Nanocomposites
SEM of salient microstructural features in WC-Co and nanocomposite samples; (a) Dense WC-Co microstructure, (b) WC-Co-2ND exhibiting increased presence of micro pores, arrows denote examples of pores, (c) WC-Co-5ND showing poorly sintered regions with high porosity, Inset: high magnification image of pores in WC-Co-5ND, the region appears to have collapsed and bonding between WC and the Co binder is poor, (d) High aspect ratio porous region in WC-Co-10ND, Inset: Lower magnification image showing highly oriented nature and prevalence of high aspect ratio porous regions.
