Method & Evidence

AimTo investigate the impact of Ni and Ni-Cr ion implantation on the corrosion resistance and interfacial contact resistance of austenitic stainless steel 316L in a simulated polymer electrolyte membrane fuel cell (PEMFC) environment.

MethodExperimental research

ProcedureAustenitic stainless steel 316L samples were subjected to ion implantation with nickel (Ni) and nickel-chromium (Ni-Cr). The modified samples were then exposed to a corrosive solution (0.5 M H2SO4 with 2 ppm HF at 80°C). Corrosion performance was evaluated using open circuit potential, potentiodynamic, and potentiostatic tests. Surface analysis was conducted using X-ray photoelectron spectroscopy (XPS), and material dissolution was quantified via inductively coupled plasma atomic emission spectrometry (ICP-AES). Interfacial contact resistance (ICR) was also measured.

ContextMaterials science, metallurgy, and electrochemical engineering, specifically in the context of materials for fuel cells.

Variables

IVType of ion implantation (Ni, Ni-Cr, none)

DVCorrosion resistance (dissolution rate), Interfacial Contact Resistance (ICR)

CVMaterial (SS316L), corrosive environment (solution composition, temperature), test duration, ion implantation dose/fluence (though this is often varied to find optimal levels).

Strengths & Limitations

Strengths

+Uses multiple electrochemical testing methods for robust corrosion assessment.
+Includes surface analysis (XPS) to understand the mechanism of improvement.
+Quantifies both corrosion and electrical performance (ICR).

Limitations

Ion implantation is a specialized process that may not be accessible for all design projects. The cost and scalability of this technique for mass production should be considered.

Reliability & validity

The use of multiple established electrochemical techniques (OCP, potentiodynamic, potentiostatic) and surface analysis (XPS) enhances the reliability and validity of the findings regarding corrosion resistance. ICP-AES provides quantitative data on material dissolution. ICR measurements add another layer of performance evaluation.
