Black chrome.......?

[98tls]

I like the look of polished wheels etc but was thinking about the odd set of mags on cars that ive seen and there kind of a black chrome....or at least a dark chrome........ive a set that i had painted but am not happy with them so was thinking of going this way for something different.........anyone know the technical name for the process and how expensive is it.........?

[degrom]

I know what you are talking about. Are you sure it's a chrome and not a powder coating?

[Maha]

Anodized???.....should look smick if you ask me, i think someone a while ago photoshoped their bike with different coloured wheels and posted on here?
Dont ask me where...

[98tls]

yea mate.........definately a chrome........or same process....theres a few of us here playing cards and everyone is sure its a chrome thing but nobody can come up with the name for it.............

[chanceyy]

boys.....drink ....cards ... drink ..... bullshit .... drink .... bullshit..... drink .....cards .... drink .... bullshit ..

yup they will not come up with the name ... :innocent:

yup they will not come up with the name ... :innocent: :yes: about it...........up to -$78.........maha...you may well be on to it with the anodized..........someone said nickel-plating........:gob: surely not......may well be the piss talking:yes:

[NighthawkNZ]

Any electroplaters will know what you are talking about (and the name)

[chanceyy]

:yes: about it...........up to -$78.........maha...you may well be on to it with the anodized...may well be the piss talking:yes:



& on when to fold the cards ;) .. them boys are taking you to the cleaners mate

[98tls]

Any electroplaters will know what you are talking about (and the name) yea fair call...........just thought the combined brain cells of the dipwits in my lounge put together with ever massing of genius's on here someone would know..........should have known.........:innocent:

I know what you are wanting but can't think of the name either... :stupid:

[Youngjim]

You can get black chrome but I don't think many electoplaters do it.
I got a gun barrel done once and it was quite expensive, so wheels would really be over the top.

[chanceyy]

[Youngjim]

Can't remember how much it was as it was years ago and as I mentioned it is a specialised application and the gunsmith had a small electroplating tank with the black chrome solution in.
I don't think that many electroplaters would have a bath big enough to do wheels but I will try and find out for you as I have a friend who deals with electroplaters.
May be after the holidays before I can contact him though.

How about titanium nitride? Thats the black coating you see on some forks these days. looks like obsidian glass i guess?

Now that sounds like the stuff they use on space-ships!!! It must be it!!!!

I think titanium nitride is the gold coloured coating, the black stuff is DLC (diamond like coating).

Some mufflers are black chromed, might be worth asking neptune.

I'm fairly certain that Forlong & Maisey on Vickery St, Te Rapa, Hamilton can do black chrome. phone 07 849 3861. Might be worth a try

[imdying]

The black chrome on wheels you've seen is 'shadow chrome'. I think that it's acually just a gunmetal coloured powercoat, and not actually chrome at all iirc.

Came to this thread late... again!

My understanding was that structural parts (frames, and I guess wheels) shouldn't be chrome plated as chrome is relatively brittle and is prone to cracking. Any such crack can then create a stress riser which can potentially result in the frame losing its structural integrity (cracking) at that location. For this reason my Cheney MX frame was nickel plated. Nickel being softer.

An engineer (or Google?) might give a more erudite explanation but I'd be very wary of chrome plating wheels.

[Ixion]

So what about wire spoke wheels then? Though vague memories of something called "hydrigen embrittlement" come to mind.

[Crisis management]

As Ixion states Hydrogen embrittlement can be a problem with chrome plated steels and additional heat treatment is required to prevent it causing cracking failures (usually an oil bath treatment for a couple of hours at something like 180 degrees)
It's been a while since I dealt with this but I think it is a problem with welded joints and high carbon steels mainly. Be worth enquiring about more before spending $$$'s on plating.

I'll have a look tomorrow and get a more definitive answer...too close to hangover recovery time today.

Titanium nitride is gold,it's the coating they put on drill bits-and forks.
The black coating on forks is Diamond Like Carbon.

Black chrome was used on some production bike exhausts in the eighties.
Katanas and GPZ's I think

The acid etching used to prepare for plating causes intercrystalline corrosion,and that can lead to cracking

Came across these on the TLZONE website.......its a powdercoat called smoke chrome

[Crisis management]

Powder coating looks like a better option than chroming!
I had a look at the process required to achieve a good black chrome finish on aluminium and it looks a lot more expensive than powder coating.
Bear in mind with powder coating aluminium alloys that the process of curing the powder coating (200 degrees in oven) actually softens the alloy. When I was involved in manufacturing coated alloy wheels we had a maximium of 2 recoats before we scrapped the wheels. So, don't go powder coating them every second week....

Is that what you are after?

[imdying]

More info.... DLC has no colour... is transparant. The black look on the GSXR1000K3 is DLC over top of black chrome.

Found that out here (http://racinglinks.co.nz/titanium%20nitride.html), a place in NZ that does TiN coating :D

Thanks mate!!! That's a contact I have been looking for,for a while now...

If you find a cheap place I'd be keen to learn about them - if it's local all the better. Ironically we're both trying to head down similar paths ... so smoked chrome finish is actually a powder coat and has nothing to do with electroplating ... seems I was whistling up the wrong tree in my other thread.


Also found this and that's made me some bit worried about my project:

Cast aluminum and magnesium parts may experience out-gassing and or bubbling in the finished powder coating. [Company] will take every precaution to avoid out-gassing, however [Company] cannot be held responsible for bubbling caused by porous coatings.
Can anybody explain what this is all about?
