Trouble Shooting of Nickel Baths

2003

Dear Sir ,

We are carrying out Nickel Plating on Ferrous Metals ( CRCA). even with the Anode Cathode Ratio of 4: 1 The Current of 30 Amps. The time being 15 minutes. The component is a Spring Washer we have got a Plating thickness of 6 to 8 Microns instead of 15Microns. please give me the Corrective Action of resolving the problem ( Technical Solution ). The Contents of the bath are maintained as per the Standards.

But why is 15 microns expected? Is it expected because you formerly achieved it, or because Faraday's Law says you should get it, or simply because you need it to meet a spec and were wishing and hoping? What is the current density, and are these parts barrel plated or rack plated?

Dear Mr. Acharya,

If the current density is 3.5 to 4.0 a/sq.dm you should get somewhere near 15 micron. But to troubleshoot your problem you need to share more information.
