The corrosion resistance of Cr-containing alloy parts made by additive manufacturing can be significantly improved a post-treatment gas-phase-based infusion concentrated interstitial solute (carbon and nitrogen). We demonstrate this universal approach for the example low-temperature nitrocarburization solid-reagent pyrolysis applied to Alloy 22 (UNS N06022) laser powderbed fusion. show that imp...

Al self-corrosion in alkaline electrolytes is a critical issue that restricts the practical application of Al-air batteries. To inhibit self-corrosion, hybrid nonionic surfactant (branched alkyl glycoside, abbreviated as BAG) and ZnO developed. Hydrogen evolution test, potentiodynamic polarization, electrochemical impedance spectroscopy are performed to investigate corrosion behavior electrode ...

This study aims to examine the potential improvement of uniform corrosion resistance and critical pitting AISI 316L stainless steel (SS) in a simulated marine environment containing 3.5 wt. % NaCl by applying layer gelatin HfO2 nanoparticles using spin coating. Also, statistical significance different weight fractions applied on protection performance. The performance was assessed from potentio...

Abstract. The potentiodynamic experiments of the nickel effects on zinc electrodeposition have been done to understand impact Ni impurities electrowinning Zn from spent pickling liquor. chloride solutions concentrations 90 and 1 g/dm3 were used as electrolytes. latter was also mixed with in experiments. All runs carried out at room temperature 40 mV/s continuous polarization speed 1/s sampling ...

in the polymer electrolyte membrane fuel cells (pemfcs), low corrosion resistance and high interfacial contact resistance (icr) are two controversial issues in usage of aisi 316l stainless steel as a metallic bipolar plate. for solving these problems, investigation and development of different coatings and/or surface treatments are inevitable. corrosion behavior and icr of aisi 316l specimens c...

PURPOSE The aim of the presented research was to find a combination of surface modification methods of implants made of the Ti-6Al-4V ELI alloy, that lead to formation of effective barrier for metallic ions that may infiltrate into solution. METHODS To this end, the following tests were carried out: roughness measurement, the voltamperometric tests (potentiodynamic and potentiostatic), and th...
