Abstract

The results of determining the porosity of chemical nickel coatings, which were obtained using electron microscopy and an image processing system, are reported. The procedure allows pores more than 10 nm in diameter to be detected. Data on changing the porosity of chemical nickel coatings subjected to full-scale tests in a sea atmosphere are obtained. A three-stage failure mechanism of cathode coatings is suggested. The service life of coatings is determined.
