Treatments for Titanium jewelry

Im trying to find someone that can help me find a durable solution for coating Ti jewelry. Anodizing just isn't durable enough for my application (wedding rings). I'm looking for a high hardness rating and the ability to gain a high polish but I would really prefer to inlay precious metals into the piece. My primary request is for black but it would be even better to find a solution where I could offer other colors as well (greens, deep reds, blues, and purples would be ideal)

Thank you in advance,

Rings are very high wear items, so I'm not sure that any coating whatsoever will be 100 percent satisfactory in the long run. If a ring can wear all the way through, which they sometimes do, anything that is a coating will obviously wear off before the ring wears through.

Still, there is titanium anodizing and there is titanium anodizing. The typical, casual, decorative anodizing done in coca-cola or TSP [trisodium phosphate [on eBay or Amazon]] is one thing, the high wear resistance AMS 2488 alkaline anodizing, and other proprietary processes, are something else. Just because the coca-cola based anodizing was unsuccessful doesn't necessarily mean that anodizing won't work. Good luck.

What about some sort of diamond plating process?

Try Everbrite [a finishing.com supporting advertiser] coating! I think that it is modified silane based coating, according to producer something best on that planet! Good luck!

There are good durable technologies of
1. color anodizing of high quality of bright colors;
2. titanium blackening (durable if titanium alloy is not 6-4 type);
3. titanium plating by Au (gold), Pt (steel color), Rh (silver color);
4. PVD of TiN type.

We can deliver technologies (1), (2) and (3).
