Relief of residual stress of electrodeposited nickel by amine as additive in sulfamate electrolyte

摘要

The relief of residual stress of electrodeposited nickel by using amine as an additive in sulfamate electrolyte is reported. It is shown that the amine additive effectively changed tensile stress into compression stress, even in the very low concentration range in the order of 10(-3) M. The changes in microstructure and microhardness by the amine addition are also presented. (C) 2017 Elsevier B.V. All rights reserved.
