Hello reader,
replating Ni over Ni is a simple process.
step:1
clean the substrate with soak cleaner.
step:2
activate the substrate by using 50% or concentrate HCL.
step:3
plate the substrate at very low current for 5 mins.(i.e.5 Amps/100 dms then apply correct current do plating well.
I Find this process by experience.
GOOD LUCK.

I will assume it is old, tarnished, and heated nickel plate. Now clean off the organic soil. Dip in the strongest HCl acid you can stand. Strike for 3 minutes in 2 pounds per gallon nickel chloride, one quart per gallon HCl, using Rolled depolarized Nickel anodes (not S-rounds), take out the anodes when not in use.
