So, we add some plasticizers in high-molecular materials to improving the mouldability and physical mechanical properties.
And we can conclude through SEM that the texture of materials which plastifying PVC are different.
The polymer chain keep entangling with each other and the materials have higher breaking strength and elongation at break.

The feed rate of nozzle and the bond materials have significant impact on the 3D surface roughness of the wheel and dressing efficient.
Several grooves were generated by abrasive water jet on the wheel surface to compare the influence of the nozzle feed rates and the different binder materials.
