XTR M900 steel sp.-black magic?

[fearfactoryüberalles]

Hi peeps,

I got a couple of old XTR M900 steel shaft' seatposts, and the black coat is severely damaged on all of them. It looks as it is anodising, as it's only microns thin, but I can't imagine how it is possible on steel material.

Could anyone enlighten me about this as I plan to re-coat them (with whatever is that black magic stuff) and trying to find a lasting and similar treatment to the OEM surface coat, pretty please???!!!

Cheers,
Endre

I understand it's a chemical blackening, probably a recipe like this: https://www.moss-metal-finishing.co.uk/ ... -blacking/

Cerakote works a treat. Only microns thick. Ive used it loads.

It’s more than likely a PVD coating (physical vapour disposition) as it is suitable for steel. There are a few companies in the U.K. that specialise with this process and it’s not ‘too’ pricey.
