The Influence of Cylindrical Grinding Medium on Particle Size and Mechanical Properties of TiC Steel Bonded Carbide

Abstract:

Ball milling is an efficient way to produce TiC steel bonded carbide. In addition to the use of alloy steel ball, a certain amount of cylindrical object are used for grinding medium and the content is 0, 15%, 30%, 50%, 100% of the total grinding body, respectively. The results show that average size of particles became smaller with an increase of the content of cylindrical grinding medium. The effect of ball milling is the best when the content of cylindrical grinding medium was 30%. Meanwhile the effect on ball milling with cylindrical grinding medium entirely is not better than that with spherical grinding ball completely. In addition, the ball milled powder is made into experimental samples after mixing glue, granulation, forming, sintering and heat treatment and son on. The particle size of ball milled powder become smaller and the green compact are sintered in lower temperature and kept shorter holding time after adding cylindrical grinding medium in ball mill, which reduces the tendency of growing up of hard phase and improve mechanical properties of the sintered material distinctively.
