“…The findings from such studies are summarized in Table 7. [133][134][135][136][137][138][139][140][141][142][143][144][145][146][147][148] In the case of CoCr, Xin, et al, 133 investigated the corrosion characteristics of SLM CoCr in artificial saliva solution-due to the applicability of CoCr-based alloys in odontology-and compared the results with a cast counterpart. The SLM CoCr (i corr = 0.02 μA/cm 2 ) exhibited similar corrosion characteristics to cast (i corr = 0.07 μA/cm 2 ) from potentiodynamic polarization in the analyzed environment.…”

Additive manufacturing (AM), often termed 3D printing, has recently emerged as a mainstream means of producing metallic components from a variety of metallic alloys. The numerous benefits of AM include net shape manufacturing, efficient use of material, suitability to low volume production runs, and the ability to explore alloy compositions not previously accessible to conventional casting. The process of AM, which is nominally performed using laser (or electron) based local melting, has a definitive role in the resultant alloy microstructure. Herein, the corrosion of alloys prepared by AM using laser and electronbased methods, relating the corrosion performance to the microstructural features influenced by AM processing, are reviewed. Such features include unique porosity, grain structures, dislocation networks, residual stress, solute segregation, and surface roughness. Correlations between reported results and deficiencies in present understanding are highlighted.

“…Different names for laser direct rapid manufacturing techniques are used including Laser Engineered Net Shaping (LENS) [1,2], Direct Metal Deposition (DMD) [3,4], laser solid forming (LSF) [5,6] and Laser Metal Deposition Shaping (LMDS) [7,8]. With coaxial powder injection, all these similar techniques are applied for the complete fabrication of 3-D, near-net-shape and solid freeform metallic components through layer by layer deposition of melted metal powder [9].…”

“…On the other hand, nickel substrates are massively applied in electronic devices [6]. Moreover, there is a significant and increasing interest in Ni-Cu alloys [7][8][9][10] which is related to their good corrosion resistance [11][12][13][14], mechanical [15][16][17], magnetic [18,19] and optical properties [20]. Because of the expressed dynamic activity of Ni-Cu systems, their role as efficient and chemically stable catalysts is of growing interest [21][22][23] as well.…”

a b s t r a c tPhase diagram of the Cu-In-Ni ternary system was investigated using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) methods. Experimentally obtained results were compared with the results of thermodynamic calculation of phase equilibria based on calculation of phase diagram (CALPHAD) method and literature data. Phase transition temperatures of alloys with overall compositions along three selected vertical sections Cu-In 0.5 Ni 0.5 , Cu-In 0.8 Ni 0.2 and x(In) = 0.4 were measured by DTA. Liquidus temperatures were experimentally determined and compared with the results of thermodynamic calculation. Identification of coexisting phases in samples equilibrated at 400°C and 500°C was carried out using SEM-EDS and XRD methods. Obtained results were compared with the calculated isothermal sections of the Cu-In-Ni ternary system at corresponding temperatures. Calculated liquidus projection and invariant equilibria of the Cu-In-Ni ternary system were presented.
