Coloring Nickel Plating
Q. I've been plating various interior car parts with electroless nickel, sanding and then clearing with Cerakote for a unique look. Pic below:
My customer would like a slight gold tone to the nickel. Is this possible? What would I need to do to achieve this result?

A. Hi Shaun.
See Goran Budija's & Khair Shishani's postings on this page regarding coloring of nickel plating. But since you are doing Cerakote on top of it anyway, I'd suggest just tinting the Cerakote. I think that will be easier and better.

Q. I have some miscellaneous, small, light, mild steel parts and tensile wires that have been nickel plated prior to my procuring them. I have a strong desire to apply various colorations to these parts for a student project and for possible future fabrications of the project's end product. Is there an established method for applying a lasting coloration to parts that have been previously nickel plated? Many thanks for your time.

A. Hello, Brandon. If metal dyes / alcohol inks ⇦ on eBay or Amazon [affil links] don't prove long lasting enough, electrophoretic lacquer is commonly applied to nickel plating to simulate brass, and it is available in many other translucent colors as well (although it probably isn't something you can do yourself). Good luck.

Q. What is the typical thickness of an electrophoretic lacquer finish? (my application requires that any coatings I apply be on the range of ~1 mm or less).
Also, do you know if flexible (thin) metal components which are electrophoretically colored will retain their flexibility, or will they be subject to cracking when deflected?
Thanks,
student - San Luis Obispo, California, USA
A. Hi, Brandon. Electrophoretic lacquer can be applied much thinner than that, say 3-5 microns.
It has reasonable flexibility ... it's paint, but applied in a way that allows very thin and even coatings.

Q. Your nickel coloration process seems simple enough and most of the chemicals seem within my abilities to acquire but ...
I am wondering if anyone can recommend inexpensive US suppliers for this chemistry (online preferred) -- since my process will definitely be a trial run and I am on a student budget.
Also - what quality of finish are you obtaining? Your responses are very educational and much appreciated.

Q. I am very interested in Mr. Shishani's process for coloring nickel. I have a number if aluminum castings that I need to color and they will not anodize. I can nickel plate the AL and then color if I can figure out how to make up the bath. I have spent untold hours on the net researching "nickel coloring" and this thread is about my only hope. I am not a chemist, but I follow directions well. I have made several inquiries to chemical suppliers and some of the items he lists are somewhat problematic to procure, but I am both patient and persistent.
Any help with this process will be greatly appreciated.

Q. I have questions about Mr. Shishani's method.
In this method electrolyzing is not used?
Or what type of Anode should be used?
Please help. Thanks

Q. How is Electrophoretic Lacquer applied to jewellery.
Syed Shafqat Naqvijewellers - Lahore, Pakistan

A. Hi, Syed. Electrophoretic lacquering is done in an electrified tank, rather similar to electroplating. The electricity converts the components that are in the solution into lacquer on the surface of the parts.

Need Red Steel options!
Q. I am currently trying to get a steel part to look red. Because of the other requirements, I'm having a difficult time finding options. The coating/treatment must be thin and durable to friction--this part is a small (5"L .75" Dia) tube that slides within another steel tube loosely, but too tight for powdercoat. The steel part can be made of stainless or non-stainless steels, if that offers additional options. PVD is the closest option I have come across but I cannot find red, only rose or red/bronze. I read on this forum that nickel plated steel can be made to look red by the method shown above, but I have no source to test the method to see the results (and I am no chemist):
The steel I have could be nickel plated if that would allow the above procedure to work with good result, but I also do not know how durable that finish would be. Any help or guidance is greatly appreciated!

Ed. note: There is a little cross-talk on a long public forum page like this, but I believe Khair said that this made a dark blue similar to gun bluing.
A. Drew,
My first recommendation would be Cerakote.
It has a high abrasion resistance, comes in many colors, as with any coating preparation is key. Follow the instructions provided by Cerakote, or if you're not equipped to do it on your own, send it out to a coater to have it done.

Ed. note: We appreciate the suggestion, but prefer describing coatings generically rather than by brand or source if possible ( huh? why?). Our understanding is that Cerakote is a thin sprayable ceramic-infused coating, available in both air-dry and oven-cure versions.
A. Hello Drew,
How about making the part undersize a hair to allow for paint?

Q. Hello Drew,
I read your post and I have the same question, in this time passed did you find any solution?
Thanks in advance, for me and for the people of the forum.
Hello Brandon,
I know a lot of time is passed, I try to ask you if you found the answer to your question based on the suggestion of Mr Shishani.
Hello, finishing.com,
I just read about some study conducted by Finishing.com for a specific coating. Maybe is there also any study conducted by Finishing.com with any supplier for red nickel plating? I'm referring to the previous suggestion for the chemical bath of the red nickel plating.

A. Hi Matteo, we will try to advise Matt and Brandon of your posting, but e-mail addresses from 18 years ago very rarely work.
Metals are not red -- copper is orange-ish, brass & gold are yellow-ish, and most other metals including nickel are silver-ish. Copper & brass, and even silver, can generate salts that put beautiful patinas on them, but I personally don't know of any decorative patinas for nickel or nickel plating. But in addition to electrocoating or painting, you might consider powder coating, metal dyes ⇦ on
eBay
or
Amazon [affil links] , or coatings applied by PVD. Transparent lacquers can be tinted to translucent colors. Titanium is readily interference colored (a partial wavelength transparent coating of the right thickness to amplify/suppress specific colors) and stainless steel can be anodized similarly although with more difficulty and not quite as pleasing results, I suppose it's vaguely possible that results could be obtained with nickel with enough experimentation.
I think the key to moving forward is for you to detail as carefully as you can exactly what you are trying to accomplish and on what sort of nickel plated parts because some processes like PVD may only be practical at large volume, some processes such as dyes and tinted lacquers may not be nearly durable enough, some may not be aesthetic enough, some like powder coating may be too thick, most will affect conductivity. A special potion you can just dip nickel into and turn it into a robust, attractive, red color sounds unlikely ... a red-tinted translucent dye, lacquer, or clear coat sounds the closest though.

Q. Hello,
We have inventory about 5,000 nickel Brand labels for our Chattam and Wells mattress brand that we are trying to see if can change to a bronze color.
Not my area of expertise, so not sure if the finishing process we're looking for is electroplating, powder coating, or something else?
The brand is being refreshed so would be great to be able to reuse these somehow. Attached some pics of the label for reference. Let me know if you have any questions, thank you!

A. Hi Shad. As brass and bronze plating became more expensive or more of a challenge because they are based on highly poisonous cyanide, it became commonplace to do a tinted electrophoretic lacquer (e-coat) on top of nickel plating to simulate the brass/bronze look. Lots of 'brass' lamps are actually tinted e-coat over nickel plating. Considering that the components are already nickel plated, it sounds like an ideal application.

A. Hi again Shad. We don't post brand or sourcing recommendations (huh? why?) but proposed suppliers can contact you privately.
However, for a study conducted by finishing.com for IZA / ILZRO a few years ago, Molecular Technology Limited in Wolverhampton, England (acquired by Coventya, acquired in turn by Macdermid-Enthone), and PMA Photometals of Arizona (photometals.com) were generous enough to supply electrocoated samples for corrosion testing, so we're pleased to mention them as potential sources :-)

RFQ: Hello,
Similarly, I'm looking to have nickel plated, carbon steel alligator clips colored. I've been doing some reading on tinted electrophoretic lacquer (e-coat) but can't find anyone in the US via google who advertises doing it.
I'm was hoping to have them colored to look similar to an anodized aluminum.
Thank you

A. Hi Matthew. I've seen socket wrench sets done that way, but they probably weren't done in the USA. They look good in the store, and it's surely helpful to know that the 1/2" socket is color A, the 9/16" is color B, the 5/8" is color C, etc. The color probably gets scratches in the tough environment that tools live in.
If you are a hobbyist doing one or two alligator clips, regular wet paint may be as practical. But electrophoretic lacquer does sound good for alligator clips, as long as the teeth don't get coated since the lacquer is not conductive like nickel plating.
Luck & Regards,
