Improving the Surface Quality and Tribological Characteristics of 3D-Printed Titanium Parts through Reactive Electro-Spark Deposition.

It can be seen that the AlSi12 electrode-coated surfaces ( Figure 4 b,c) are more uniform and smoother than those of the NW electrode ( Figure 4 f and also that with increasing pulse energy, the roughness and surface irregularities show an increasing trend.
