Principle 3
Metal contact seawater corrosion is because the water contains a variety of salts, in which the highest content of chlorine salt. Seawater corrosion is characterized by corrosive
Residual products of sea-salt particles using scanning electron microscopy and X-ray spectrometer to detect corrosion products and components in sea salt particles, in order to ensure
Given seawater corrosion.
