WC-Co　cemented　carbide　bulk　materials　with　anisotropic　distribution　of　specific　WC　planes　were　prepared　by　spark　plasma　sintering　(SPS)　using　different　pre-sintering　temperatures　of　850　degrees　C,　900　degrees　C　and　1000　degrees　C　at　a　constant　pressure　of　60　MPa.　The　coincidence　site　lattice　(　CSL)　grain　boundaries　were　characterized　and　the　anisotropic　distribution　of　the　CSL　boundaries　was　demonstrated.　The　combined　effects　of　the　composite　powder　and　the　SPS　parameters　on　the　formation　of　the　anisotropic　CSL　boundary　distribution　were　analyzed.　The　mechanisms　were　proposed　such　that　the　CSL　grain　boundary　distribution　can　be　tailored　by　adjusting　the　composition　of　the　composite　powder　and　the　SPS　processing　parameters　such　as　the　pre-sintering　temperature,　sintering　pressure　and　its　working　stage.　The　findings　facilitate　to　obtain　a　beneficial　CSL　grain　boundary　distribution　that　enhances　mechanical　properties　in　certain　directions　of　the　cemented　carbide.
