К вопросу изготовления цинковых электродов сравнения для морских судов и кораблей

Abstract

The article highlights the urgent problem of corrosion protection monitoring of sea-going vessels and ships. Nowadays, the ship teams provide the control by measuring the potential of the ship hull using reference electrodes. There are given the results of monitoring the corrosion protection of the hull of the sea-going vessel PM-15 project No. 304/III. The control system is based on the results of measuring the potential of the ship hull. The measurements were taken using a standard silver chloride reference electrode (SCE) and two nonstandard electrodes made of galvanized steel. In manufacturing the non-standard reference electrodes there were taken into account the requests of the crews of sea-going vessels of the Kamchatka fleet. Testing the reference electrodes of galvanized steel proves that the results of measuring the potential of the ship hull can be classified as accurate measurements in accordance with GOST R 8.736-2011. The measuring results are quite stable according to GOST R 8.736-2011. It has been stated that the cost of CSE is several times higher than the cost of reference electrodes made of galvanized steel. The process of storing and transporting CSE is more labour-intensive compared to the galvanized steel reference electrodes. The galvanized steel reference electrodes provided for protecting the marine hulls from corrosion are recommended for use. It has been inferred that manufacture and application of non-standard reference electrodes on ships can be provided by ship repair crews. The study results can be used by the crews of sea-going vessels to control the protection 
 of ship hulls against corrosion.
