Summary
- - Electrochemical property analysis of interface reactions between electrolyte and surface layer with impressed AC or DC current for offshore materials and coatings
- - Measurement of chemical electron transfer phenomenon and electrical energy with three-electrode (working, counter, reference)
- - Evaluation of corrosion resistance for offshore materials and investigation of corrosion protection design condition (current density*, potential**)
* Current density : Amount of current per unit area(m2) required to cathodic polarize the structure
** Potential : Driving force for oxdiation and reduction - - Electrochemical Impedance spectroscopy and Plot fitting analysis for marine coating materials
- - Quantitative value measurement using circuit design and fitting of Nyquist and Bode plot
- - Technical Standard
1) ASTM G3-14 - Standard practice for conventions applicable to electrochemical measurement in corrosion testing
2) ASTM G199-09 - Standard guide for electrochemical noise measurement
