Hydrogen Desorption and Internal Stress in Nickel Coatings Obtained by Periodic Electrodeposition

摘要: Periodic electrodeposition is performed in order to determine what extent a change conditions for the desorption of hydrogen from nickel deposits, which occluded during plating, can affect their internal stress. The duration pause (zero current), , varied range 0–900 s and plating period, kept constant, maintaining structure unchanged. variations stress, microhardness, coercivity electrodeposits obtained at different are investigated. amounts leaving coating, both pauses after deposition completed, determined. A proof mechanical nature intensive codeposition beginning electroplating obtained. It shown that responsible considerable high tensile stress observed similar coatings.
