METHOD FOR ELECTROCHEMICAL TESTING OF METAL SPECIMENS FOR CORROSION RESISTANCE

摘要

The invention relates to the field of testing materialoa object of the invention - to increase reliability of the approach ss test conditions to MaTepnanoBi operating conditions used in the construction of marine structures. A method of electrochemical tests on the corrosion resistance of metallic materials sample lies in the fact that the samples are placed in a corrosive environment, part rizuyut floor samples from an external source, is kept a predetermined time and determining a parameter which is judged on the corrosion resistance. The working surface of the samples is performed in the form of equal area circles and arranged patterns such that their centers located along the length of the two circles concentric with the reference electrode and at equal distances from each other in one plane, polarizable and non-polarizable samples were housed in groups in various portions of the circles with respect to a reference electrode, and a distance I from the center of the sample disposed on the first and second circumferences to reference electrode is determined from the relations I -26 and I 3d, where d - diameter of the sample Ztabd
