Variation of Surface Roughness of Ti₃SiC₂ Disk during Polishing in Water and Alcohols

Abstract:

The surface polishing of Ti₃SiC₂ disk in fluids (water, ethanol, propanol, glycol, and glycerol) is conducted on a Buehler grinder/polisher and evaluated using surface roughness. Using Buehler automatic grinder/polisher, the Ti₃SiC₂ disks are grinded and polished in the as-mentioned lubricants by grinding disk of diamond with sizes of 45 μm to 3 μm. The surface roughnesses of Ti₃SiC₂ disks at each stage are measured by 3D surface profiler. The results show that the lowest surface roughness (Ra) of Ti₃SiC₂ disk obtained by mechanical polishing is 0.04 μm. The optimum polishing process of Ti₃SiC₂ disk is as follows: using water as lubricant, at a load of 5 N, for steps 1 to 4, the Ti₃SiC₂ and grinding disk rotates comparatively and the sizes of diamond particles on the abrasive disk are 45, 15, 9, and 3 μm, respectively. For step 5, the abrasive disk is woven cloth with no diamond particles. The duration of each step is 5 min. Using the same polishing process, the surface roughness of Ti₃SiC₂ disk by direct hot pressing is lower than that by in situ reactive hot pressing. Using the same polishing process but different lubricants, the surface roughness of the Ti₃SiC₂ disks increases in the order of water, ethanol, propanol, glycol, and glycerol. In water, the surface roughness of Ti₃SiC₂ disk decreases with the increasing quantity of water and polishing duration.
