In this work, an attempt is made to improve the electrochemical corrosion resistance of Zircaloy-4 by helium ions implantation. For this purpose, the Zircaloy-4 was implanted with 300 keV helium ions of fluences 1 × 10<sup>13</sup>, 1 × 10<sup>15</sup>, and 1 × 10<sup>16</sup> ions-cm<sup>-2</sup> by using Pelletron Accelerator. Electrochemical tests of pristine and ion-implanted samples were performed in NaCl solution and their potentiodynamic polarization curves were obtained. The results showed enhancement of the corrosion resistance of Zircaloy-4 after helium ions implantation. The corrosion rate and current density of the material were significantly reduced by the helium implantation. The decrease in corrosion parameters was attributed to helium ions diffusion inside Zircaloy-4 that reduced the electrons flow from the samples.

The electrochemical behavior of 3D printed 316L stainless steel (3DPSS) was investigated in phosphate buffer saline (PBS), containing β-Lactoglobulin (BLG). The charge transfer resistance (Rct) was decreased from 629 to 40 k Ω cm2 with an increase in temperature from 293 to 323 K in BLG free electrolyte. At each temperature, the exponential decrease in the polarization resistance (Rp) of 3DPSS was a function of BLG concentration. The significant decrease in activation energy ‘Ea’ (∼15 kJ mol−1) upon adding 0.06 g/L BLG attributed to the charge transfer process involved in the adsorption process. The results were further used to quantify the thermodynamic parameters.
