Comparison of the electrolytic, ultrasounds and chemical cleaning in corroded naval steel

Oxygen, salt and water are key factors afecting metal deterioration and leading to corrosion in a marine environment. Prolonged corrosion may compromise the use of the materials and this may have an important economic consequence, since the cost derived from its prevention may be much greater than t...
