Anodize spray paint

(Click here to view the original thread with full colors/images)

Duplicolor just came out with a spraypaint that resembles anodizing, you have to prepare the surface a certain way and just spray it on and it looks anodized, comes in blue, red and yellow I think, anyone tried it yet???? looks like a good product to test out on bolts to see if it really works, I was even thinking my chain adjuster blocks, I'm gonna get some this week, I'll let you guys know,

It looks nice there, but I can't imagine that it's easy to put on at all. Also, anodizing really changes the metal, and this is only a surface thing...why don't you just get your parts anodized?

Uh how EXACTLY is the aluminum changed with anodizing? I was under the impression it was an oxide type finish to the surface of the aluminum that was porous enough to allow color to be added. Silly me. :silly:



Posted by: yzeater---------------------

Maybe I'm wrong Patman...not looking to pick a fight. www.anodizing.com

The purpose of anodizing is to form a layer of aluminum oxide that will protect the aluminum beneath it. The aluminum oxide layer has much higher corrosion and abrasion resistance than aluminum.

Most anodized products have an extremely long life span and offer significant economic advantages through maintenance and operating savings. Anodizing is a reacted finish that is integrated with the underlying aluminum for total bonding and unmatched adhesion.

Maybe I'm wrong. Silly me

Now Patman, don't go adding any knowledge of how things work to a discussion! :D



Posted by: yzeater---------------------

my bad, the website is www.anodizing.org So I DID make a mistake!

Point being that your not "changing" the aluminum, just applying a surface finish. Check out the fancy anodized wheels some folks have it's pretty easy to tell if they have changed a tube/tire and/or ride in rocks. Is it better than the paint? Sure if cost is not an object then by all means drop the item in the tanks and crank up the power. Once the surface is scratched though be it the paint or actual anodized surface the underlying material is the same, it has not been "changed".

dictionary.com's definition of change is "to give a completely different appearance to"...



Posted by: CanadianRidr---------------------

Can we just agree to disagree here?
I think Pat said, it will change the appearence of the metal, but it will NOT change any of the characteristics or properties of the metal other than just the color on the surface that can simply be scratched off and then you are back to good old stock

Yes but the composition of the metal remains unchanged.

I saw Duplicolor's ad in my latest Dirt Rider. Looks nice.

um....so by the way has anyone tried it? That is what this post was originally about by the way.

You can call Chad Young (817-975-9639) or Phil Horton (817-688-0052) at LoneStar Anodizing, and they will take care of you. They are very affordable.

I guess it depends on your definition of change. :confused: Just kidding pantless.

My son-in-law tried it on my grandsons hubs. Looks ok. It is a two part process with a base coat and a translucent top coat. Still looks a little more like paint than true anodizing. Also, depends a lot on how well it is applied.

Just my opinion.

I put it on my stock silencer and it doesn't look too bad. It is holding up well too, it doesn't scratch very easy once it is dry. The roost hasn't scratched it off yet.

The composition of the metal does change where it has been anodized. The anodized portion (surface) has been oxidized. Usually we think of oxidation as corrosion or "rust". In the case of aluminum, a layer of oxidized metal forms which prevents further oxidation from taking place beneath it. We think this is good. Not only can we prevent our parts from corroding away, but this layer of oxidized aluminum happens to be very hard when compared to the base metal. We have simply learned how to control the thickness of the oxidized layer and use this to our advantage. Controlled corrosion is what it really boils down to. The color is just foo foo that we add for fun. Immediatley after the anodizing process has finished, the surface or oxidized portion is very porous. Not like a sponge. Think of it as porous at a molecular level. Just enough so that we can dye it the color of our choosing. After applying the dye, the parts are rinsed in boiling water which again changes the chemical properties of the surface layer to the point that the color is locked in. The surface is no longer porous.

If I remember my basic welding correctly, all aluminum, whether anodized or not, has an aluminum oxide coating on it. It happens when aluminum is exposed to air. That is why gas welding aluminum is next to impossible, because the aluminum oxide actually has a higher melting point than the raw aluminum beneath it. Oh, and please don't make me type aluminum any more.

I tried this product or at least I think it was duplicolor except mine was green. I put it on the head of my bike and it didn't turn out great but it has held up. The problem could be that metal was rough cast and not flat surface. I doubt it would work well for bolts.

From what I understand about the procedure, scroskrey is spot-on.
We are actually "growing" a layer of oxidation that resides on the substrate of the metal. This growing of oxidation is in fact changing the surface hardness of the metal. TypeII is a simple oxidation growth and used when colorizing, and typeIII is a "hardcoat" type...which simply means the aluminum oxide is thicker (and harder).
If you doubt that anodizing changes the hardness of the metal itself, try running a Rockwell on both anodized and non and see what you get.

BBS exist for just about everything these days.

I've used the duplicolor stuff, it's been out a while, I used it on plastic though just to get a stupid new look, it didn't last really long but that's alright, a quick fix until I got my new plastic. Application was easy, surface prep for no metallic surfaces requires a basecoat which is nothing more than chrome spray paint. Turned out nicely though, link to a pic below. http://www.dirtrider.net/teamdrn/sh....php?photo=4137

[QUOTE it will NOT change any of the characteristics or properties of the metal other than just the color on the surface ]

I believe it changes the properties of the "surface layer" of material making it actually harder. Granted this is just one surface layer of molecules which can be "scraped off".

You can also scrape off the hardness of a case hardened steel part.
