Can you anodize chrome

The "bright" version did not fade. I am attaching two pictures. One compares the front of two "bright" moldings on the left to the front of two black moldings. The second picture shows the backside of these same rockers. In this case you can see the black clearly.

What I am trying to figure out is how the "bright" ones the two on the left were finished. Are they chrome plated? Are they anodized? Known for its resistance to corrosion, decorative properties, hardness, and durability, applications of chrome escalated after the second industrial revolution. While the future of the chrome industry seemed bright at the time, there have been several developments that indicate otherwise.

As a result, the hunt is on to find and develop viable alternatives to chrome, such as anodized aluminum. In the automotive industry, the most common form of chrome used is hexavalent chromium hex chrome but in the s , hex chrome was found to be carcinogenic in nature after multiple incidents of lung and nasal cancer amongst workers arose.

It was not, however, until that the U. Hex chrome has been proven to result in severe health issues not limited to cancer, but also including irritation of the nose, throat, eye, and skin, and damage to the kidney and liver. If I have some chrome parts that I want to get anodized, how does that work? Do you need to strip the parts? How much does that cost and can an anodizer do it? Stripping chrome creates hazardous waste. You need a professional shop to do it, then send the part for beadblast or polish, then anodizing.

Anodizers usually do those last two steps, but rarely strip chrome. But good luck. Phosphoric acid anodizing does not take dyes and it produces dull grey anodic coating on aluminum surface. Therefore, PAA cannot meet your requirement.

Titanium anodizing itself can produce bright colors. Both anodized aluminum and titanium can be further plated in terms of proprietary processes, including final chrome finish. For the same reason that you cannot disclose your application, the proprietary processes for plating anodized aluminum cannot be disclosed here.

But this does not prevent you from developing your own processes. It can be done for sure. Good luck! My approach would be to PVD coat the surface. We regularly deposit coatings with different colors, and often layer them. It would be very easy to apply a specific color, say gold, on the surface, then apply a silvery coating on top of it.
