Nickel plating of Steel Wire Problems & Solutions


An ongoing discussion from 2001 through 2016 . . .

(2001)

Q. Dear sir,

We are using nickel plated steel wires inside our metal halide lamps. After burning the lamp for some time we observe the NPS wire has changed in color to slightly bluish tint. This happens only in the hottest zone of the lamp. Since the entire system is operating under nitrogen atmosphere, this appears not due to oxidation. What could be the probable cause?

All info and suggestions are welcome.

Thanks in advance.

Adhesion on Nickel plated steel wire-Thick plating

Nickel Plating

(2007)

Q. We are Nickel plating on steel wire on continuous plating machines. The wire have reasonably good adhesion when plated with Nickel Sulphamate bath but poor adhesion when plated with Nickel sulphate bath.I am told that nickel fluoborate bath is also used and this give very good result. Can any body suggest the advantage of each process related to plating steel wire on continuous plating line. The wires are used for making lead in wires for electric lamps.

A. Hi Ashish,
You are doing a flash Ni.plating.Will you be able to increase the thickness!.
Alternative- dry well and keep it in a moister free atmosphere and transport it to the customer as soon as possible.

We nickel plate copper wire; now need to plate steel wire

February 10, 2016

Nickel and Chromium Plating
Dennis & Such

Q. A client asked us if we could electroplate steel wire for them (around 13 AWG), in the company I'm working with we already electroplate copper wire with nickel (same size) using sulphamate nickel. We use a solution called Ronaclean for degreasing and then a Sulfuric Acid (5% v/v) for pickling with water baths in between prior to the nickel plating itself.

Could we, with these chemicals, plate steel wire with nickel?
What would be the average voltage rate at which we could be plating nickel on to steel wire? (I assume it's different from copper wire)

Thanks !

A. You may be able to plate steel wire in your present setup, but the bare wire will have to be clean and free from surface oxidation. 5% sulfuric will not remove very much rust, and only slowly, although it is strong enough to activate clean steel.

And steel wire will have to be processed at higher mechanical tension to control it's path.

A. Hello Humberto, The current process you have to plate Ni over Cu will not work for plating steel wire. There are a few tanks and cells you would have to add to your line, such as a HCl dip, a low efficient Chloride Ni Strike, more rinse tanks, etc. Something I'm sure you don't want to invest in for one order. Best Wishes to you.
