Abstract This paper describes the results to date of research done to compare and contrast the tribological properties of nano-structured tungsten carbide-cobalt composites consolidated by selective laser sintering (SLS) and conventional grain size composites of the same chemical composition consolidated by conventional commercial methods. The powder preprocessing and selective laser sintering methods will briefly be described. The tribological testing methods will be discussed, and the tribological properties of the selective laser sintered and commercially consolidated materials will be compared. It will be seen that the nanosized WC-Co composites have far superior hardness and wear resistance compared to their rnicrosized counterparts. (Auth abstract) [No References]
