Sintered iron specimens with a 9% porosity level were successfully coa
ted by electroless nickel deposition using a hypophosphite bath. The p
roblems encountered during the deposition process are discussed. Some
important deposit characteristics such as composition, thickness, hard
ness, and adhesion strength of the deposit are also reported for both
as deposited and coated specimens heat treated at 400-degrees-C for 1
h in a vacuum.
