Darkest Colour of Steel Suitable for Brake Discs...
I'd like to have dark coloured brake discs on a bike project.
I see that some companies do black coloured discs, but my understanding is that it's just a coating that scrubs off within a few miles use.
Can anyone point me in the direction of a suitable material that stays black till the death (of the disc!).
Cheers!

I cant see this being possible... atall.....Any suitable metal will be shiny and silver... Only option is going to be carbon ceramic...
Or a cheaper option would be to fit floating rotors on an annodised alloy spider...like these

I looked heavily into the chemical black process and they advertise its good for disks, gears and any mechanical metal part. Its not!
I tested it by kicking it across my workshop floor, didnt last one length!
We are very precise with testing at my work, especially when my boot is involved!!
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

I have EBC Ultimax disks on my car. They start off all black, then friction from normal use rubs the colour off the area covered by the pads, leaving
the grooves and edge of the disk black.
much better than standard disks that rust on the edge.

You mention 'bike project', does that mean you're looking for bike discs rather than car discs? If so, I think this is what Tegwin
is talking about, have a look at the brake discs in this auction;
Front Rear Brake Disc Rotor Set Suzuki TL1000 S R 1997 1998 1999 2001 2002 2003 | eBay
ZC906-2-ZC848
As you can see most of the disc is black, only the thin rotor is silver. Depending on your application, you might be able to find an even thinner
friction material on a bigger spider.
(By the way, don't buy those actual discs, they are probably the worst discs I've ever seen on Ebay!)

The one time I saw black discs being used (black diamond rather than EBC) the edges still managed to rust through, it just took a bit longer. 
Although the grooves being black is quite cool.

Chemical blacking by Phosphating is very good for new camshafts because in retains an oil film better than bare metal during the initial running
in period but it quickly wears off.

Been taking a break from the trike through sheer indecision and been playing instead with a 1200 Beemer drive-train / swingarm, R80 frame and KTM
superduke front end.
This bobber was my original inspiration...
Since found these (but I suspect getting the tank right would be a PITA)...
Even being turned onto the cafe racer look (doubt my back would cope with much time sat in the saddle of one of those though)...

Mine have been on the car for over a year now - still no rust.

I used EBC race pads on my race bike and they seem to blacken the discs - they're not burnt, it's just the residue. I can get the exact
pad compound this weekend if you're interested.
Have a look here . . . Honda CBR600 FY Front wheel with disks and low wear Dunlop Qualifier RR tyres
Sorry to shamelessly plug my items for sale but they're the only pictures of my front disks that show what I mean.

It won't do black but only braking really hard may keep them blue.
Tell them about the bent treacle edges!

Metal is silvery, pretty much universally. Best you can hope for is pads that stain the surface as they bed.
