Method of electrodepositing a low coercine force, corrosion-resistant alloy of nickel, iron and boron

摘要

The present invention deals with alloys consisting essentially of the elements nickel, iron and boron. Boron is present at from 0.1 to 2.0% by weight; iron is present from 17 to 27% by weight and the balance is nickel. The alloy has high resistance to corrosion and Ho and Hc are less than 0.1 Oe in films 3000 ANGSTROM thick. It is prepared by electrodeposition from a bath having a pH of 2.5 or less, and containing a borane reducing agent.
