“…9 The use of small scale electrochemical cells, called microcells, is certainly not new, and since the mid 1990s several researchers have been developing studies based on their design. [10][11][12][13][14][15][16][17] Most of them are capillary based droplet cells, except that presented by Vogel and Schultze 15 which allows the continuous flow of electrolyte, optical control and temperature regulation. Nowadays, capillary microcells are well established in electrochemical surface analysis, including corrosion.…”

A specific electrochemical cell for small scale electrochemical testing has been built. The electrochemical cell has been made bearing in mind the microstructural features of the stainless steel weldments and the performance of the design has been verified. Two polarisation methods (potentiodynamic anodic polarisation measurements and cyclic potentiodynamic polarisation measurements) and two reactivation electrochemical techniques (the electrochemical potentiokinetic reactivation test, EPR, and electrochemical potentio-kinetic reactivation double loop test, EPRDL) have been applied to two austenitic stainless steels: AISI 304 and AISI 316L. The results are reliable and have been compared to large scale experiments. Scanning of the welding joints has been performed and the results have been correlated with their microstructural features. It, thus, makes it possible to study the intrinsic heterogeneous microstructures such as the heat affected zone of a welded joint.

“…of single grains in welds, or single micron-sized particles in metal. Vogel & Schultze (1999) combined a microcell and optical/ laser microscope to investigate local reactions on the micrometer scale. A considerable disadvantage in those studies was that these measurements could not directly record the response or reaction on the surface as a function of time, such as the time-resolved response of a pit initiation or dissolved inclusion, because the detailed examination of the exposed areas were always performed after the electrochemical measurements.…”

Practical Aspects of Electrochemical Corrosion Measurements During In Situ Analytical Transmission Electron Microscopy (TEM) of Austenitic Stainless Steel in Aqueous Media

et al. 2017

The capability to perform liquid in situ transmission electron microscopy (TEM) experiments provides an unprecedented opportunity to examine the real-time processes of physical and chemical/ electrochemical reactions during the interaction between metal surfaces and liquid environments. This work describes the requisite steps to make the technique fully analytical, from sample preparation, through modifications of the electrodes, characterization of electrolytes, and finally to electrochemical corrosion experiments comparing in situ TEM to conventional bulk cell and microcell configurations.

“…With SDCM all common electrochemical measurements such as cyclic voltammetry, chronoamperometry, potentiometry and electrochemical impedance spectroscopy can be performed [3]. Within the last 15 years various types of SDCMs such as flow-type SDCM (FT-SDCM) [4] and V-shaped SDCM [5] for electrochemical flowthrough experiments or photoelectrochemical SDCM (PE-SDCM) [6] for local photoelectrochemistry have been developed. Until now SDCM has been applied for example for high-throughput screening of thin film material libraries [7,8], microstructuring of surfaces [9], local anodisations for plastic electronics [10], direct writing of anodic oxides [11], localised measurements on bulk samples [12][13][14][15], impedance measurements on the microscale [16] and online monitoring of reaction products by connecting the output of a FT-SDCM to external analytics such as ICP-MS [17,18] or ICP-OES [19,20].…”
