| Sumario: | Nowadays, in the Corrosion Research Centre (CICORR) of the Autonomous University of Campeche, an electrochemical characterization route is being developed using the Electrochemical Scanning Microscopy technique (SECM). It is been used on different systems oriented to the study of localized corrosion. This requires the construction of the ultramicroelectrodes (UME); which are essential instruments for the technique application; through which is possible to study high resolution electrochemical processes in the interface of a substrate in solution; by visualizing the electrochemistry of topographies and surface reactivities and films. The ultramicroelectrodes construction is performed quickly and systematically using an automatic micropipette extruder Sutter Instrument P-1000; by previously defining the glass characteristics, filament type and ultramicroelectrode type to be obtained. Based on this, the equipment can be programmed minimizing errors for the required purposes. Subsequently, the properly manufactured instruments are subjected to the respective calibration process. |
