摘要: Abstract The present work aims are to study the dry sliding wear behavior of WC-12 wt%Co materials, with or without addition Cr 3 C 2 /VC grain growth inhibitors, and sinter them by two different consolidation techniques: conventional sintering spark plasma (SPS). tests were performed on a tribometer ball-on-disc configuration using WC–Co ball as counterpart material normal contact load 60 N, distance 10,000 m speed 0.1 m/s. influence inhibitors techniques in sintered samples related friction coefficient, rates pattern damage. Samples non-conventional technique (SPS) show best resistance lower coefficient. reduces materials consolidated both techniques. differences damage microstructural parameters, mechanical properties rates.
