Effect of Chloride Ions on the Corrosion Characteristics of Nickel in 0.1N HClO4

摘要: Abstract Nickel dissolution and hydrogen evolution reactions in deoxygenated perchloric acid at various pH values chloride ion concentrations have been investigated. The rate of nickel increased as the concentration Cl− increased, reaction order with respect to is 0.4. decreased slightly increased. First dependence on H+ was observed. Corrosion behavior H2SO4 also examined compared results obtained for HClO4.
