Anodising fork legs, dlc coating stantions


Acid

Recommended Posts

Hi all i,m in the process of rebuilding the front end of my Nc30 and wanted to know who does anodising of fork legs, I want my current legs stripped and redone another colour ( i have RWU forks) and how much would it cost ?

Also i would like to get my fork stantions coated in DLC ( more for looks than anything else) and again who and how much.

I will update and post pictures of the build as i go along

I think Reactive suspension might be the people to talk to, I was trawling their site yesterday and noticed they offer these services.

Acid, K-tech will sell you DLC coated tubes for £200 each (TiN for £150 each), they don't do your old ones since they need a perfect surface. So if it's just for looks I would have the old ones blackchromed which is far cheaper. Anodising is fairly cheap aswell (£50-80 for the lowers I would guess), with anodising go for hardanodising (same colour as renthal sprockets), that will lower internal friktion a bit and stop the inside of the lowers contaminating the oil with alloy shavings/oxide.

You will struggle to get anyone to anodise your lowers if they're cast... Believe me I've looked into this a lot. How about a nice powder coat instead?

As for black chrome... Who is gonna do that? You could get your stanchions hard chromed and re-ground but not black chromed... Unless someone knows different... :tumbleweed:

Hi my 2p worth, you could get the fork bottoms anodised, but you would have to remove all steel bolts studs etc etc ( cos it screws up the acid/anodising/whatever) and the colour will come out shit, cos they is cast aluminium. Was told this when I asked a few years ago about having some stuff anodised. Not sure about the tubes.....

Any decent suspension specialist should be able to sort it.

Guy i use quoted me £120 per leg for DLC coating. The origional legs are ground and coated. The fork lowers can be anodised, any ally part can be but the quality varies depending on the quality of casting. The hard anodising might be an option but as its not a wear part and only for show i dont think it would serve any benefit vs the additional cost.

I didn't say you couldn't do it... But you will not get a good finish with the forks mentioned unless you know someone (very) specialist.

I concur with Honk's opinion on this, the anodising is only going to be as good as the parent metal. Generally in my experience, castings tend to give a mottled effect to the anodising because of the cast granular structure of the metal, unlike your rear-sets etc. which would be made from a wrought material and is more homogeneous.

The best finish in my opinion, (for what it's worth) is definitely to go for a nice black semi-gloss powder coated finish which is what I've done to my TRX sliders.

As far as DLC coating is concerned, it costs a fortune to have it done properly because is isn't just a case of grinding the stanchions, they have to be superfinished in a rumbling machine which takes an absolute age. I know this because I used to work in motor-sport and we used the process on finger followers, gudgeon pins, pistons and the like. Properly done by a CVD sputtering process, you have to first coat the stanchions with Titanium Nitride (standard gold colour) to a depth of about 3 microns. The DLC then gets coated via the same process to a coating depth of 3 microns or thereabouts.

That's the reason why GSXR1000 stanchions suffer with the coating coming off - it was done on the cheap!

But you pays your money and takes your choice.
