Erosive wear of WC based alloys with different cobalt content or Vickers hardness (Hv) was investigated by blasting SiC particles on specimen surface of the alloys. The erosive wear volumes were measured by the weight variation of the specimen and the profile of erosive wear scar obtained by surface profilemeter, which were expressed as Vd and Vp, respectively. V d of the alloys was also compared with that of commercial ceramics.<BR>The results obtained were as follows: (1) The value of V d which decreased with the decrease of cobalt content in the alloys was nearly equal to that of V p. (2) V d decreased with the increase of Hv. Namely, Vd was estimated as a secondray function of Hv. (3) Vd of the alloys with low cobalt content of 0-2mass%, however, was smaller than that of B<SUB>4</SUB>C and SiC ceramics having nearly the same hardness.
