Effect of Plasma Nitriding on Structure and Properties of Titanium Grade 2 Produced by Direct Metal Laser Sintering

Abstract This article presents the effect of an Indirect Plasma Nitriding process on microstructure and properties Titanium Grade- 2 samples manufactured by Direct Metal Laser Sintering Method (DMLS). It was determined, based morphological analysis that physical chemical phenomena occurring at surface during nitriding has a decisive roughening. Phase stress shown nitrided layer produced in pure nitrogen 760 °C containing TiN + 0.30 Ti N is under compressive its characteristic high hardness Young Modulus as compare to Grade titanium only DMLS technique (without nitriding). Static tensile carried out room temperature show have much lower yield (YS0.2) strength (UTS) compared not samples. Tests Ringer’s solution, using impedance potentiodynamic methods temperatures elevated 36.6 ± 0.3 simulate human-’s’ body temperature, increased corrosion resistance alloy.
