Effect of Laser Emission Parameters on Mechanical and Physical Properties of Cast Pure Titanium

Figure 7

Hardness depth profiles from cast surface for control specimens (grade 2: black solid line, grade 3: red solid line) and specimens laser-treated with several emission currents (200 A, 220 A, and 240 A) at a constant pulse duration (10 ms) and a spot diameter (1.0 mm).
