The Prevention of Cracking in Nickel Electrodeposits

Abstract

The serviceability of nickel electrodeposits of adequate thickness mainly depends upon their physical properties. Methods of determining the internal stress and the ductility of these deposits are given. The use of these techniques in production control is illustrated by a typical case-history of a bright nickel-plating solution. The large variations in physical properties obtainable from any one type of solution are discussed and procedures for improving these properties are suggested.
