"Matte black, abrasion resistant finish for titanium"

2004

I am designing positioning clamp out of titanium for an optical sighting device and am having trouble finding a mil spec finish that will be matte black and provide abrasion resistance. We chose titanium for to the weight constraints required by our customer. The clamp is rectangular and about 1/4 the size of a credit card. We are looking at an initial build of 100 pieces with 1000's to follow upon production release. To date I have looked at powder coating, anodizing and electrocoating and have ruled out anodizing due to the low abrasion resistance. Any suggestions or other finishing options I have missed?

Thanks,

Black matte finish can be obtained on titanium by proprietary titanium blackening technology. This is very new development, and so far the best dark black color (matter or bright) can be obtained on titanium grade 1-4. Other titanium alloy give dark-dark grey or light-black color. We are still working on improvements. Titanium blackening is formation of black oxide layer of 1-2 micron thickness, which is very durable and corrosion resistant.

PVD coating the part will be more than adequate for any of the constraints required by your customer.

Dear Sirs, I'd like to anodize a titanium bolt in Black. I made a sample with 180 V and PO4H3 and I just got dark grey. Please could you tell me how can I get black?
Thank you for your help.
Regards.
