Electrochemical impedance spectroscopy study of the passive state of 316L/2205 dissimilar welded joints
The electrochemical behaviour of the passive film formed over the surface of dissimilar welds of AISI 2205 duplex stainless steel and AISI 316L austenitic stainless steel was evaluated using electrochemical impedance spectroscopy (EIS). Gas metal arc welding (GMAW) of the plates, 6.35 mm thick, was performed using ER309L and ER316L-Si filler wires with pulsed (GMAW-P) and spray (GMAW-S) transfer modes. The passive film resistance was determined conducting EIS tests at different anodic overpotentials (0.05, 0.150, 0.250 and 0.375 V). The results showed that increasing the anodic overpotential up to 0.250 V, led to the formation of a thicker, continuous and stable passive layer.
期刊介绍：
Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences.
A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below.
The scope of the journal includes:
1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes).
2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis.
3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification.
4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
