Application of Origin in Material Corrosion Experiment
By using the electrochemical methods of polarization curves and alternating-current impedance and drawing curves with Origin software as well as fitting and analyzing the data of the analytic experiments, the corrosion law of the carbon steel in stratum water containing CO2 at different temperatures is researched in this paper. The result shows that the material corrosion in the simulated stratum water containing saturated CO2 at different temperatures is active dissolution process and is mainly subjected to the activation control. The temperature rise increases the reaction rate of the reactant in the medium while promoting anode process and cathode process so as to increase the corrosion rate of the carbon steel. And, the auxo-action of the temperature to the cathode process is bigger than the anode process. The examples prove that the Origin software can conveniently draw the curves as well as rapidly and accurately analyze and fit the experiment data. The processing process is convenient and rapid, which can save much time than the manual calculation and works better than other professional mathematical analysis software because it does not need programming.
