Default Chrome Plating Wheels?

I'm considering chrome plating a set of 2013 Corvette Q5V machine face cup style aluminum wheels. I don't want to compromise the safety aspect of the wheels. Anyone know of any negative reason not to do this? Thanks

If you do this PLEASE post some good pics. I'm thinking of doing the same thing. What can i say-I'm ol' school and think hot rods should have chromies (and a cue ball shift **** and a 427)!

Probably cheaper to trade someone on the forum who wants painted wheels. You could work out a deal that's advantageous to both.

There is a reason GM doesn't offer Chrome on all wheel styles. Part of the reason is Hydrogen embrittlement of the Aluminum, it weakens the Aluminum of the wheel.

My understanding is that aluminum is not subject to hydrogen embrittlement.

GM offers chrome wheels on their two highest horsepower Corvettes...the Z06 and ZR1. GM isn't worried about the wheels falling off them.

from what I understand, no problems w. chroming wheels. I also have had a different process done on my wheels at calchrome with very satisfactory results.

I think GM probably has stricter quality control (higher price?) for the Chrome wheels, less strict (Cheaper?) for painted?

There shouldn't be any safety issues with plating the wheels but the real trick is to make sure whoever does it knows how to properly prep and plate them. The PO of my 06 put some chromed repros on that were not done well and are already starting to peel. Luckily, the problem is only in the barrels and not the face, for now.

No dog in this discussion but thought I should offer this (reminder) caveat from 2007 when there was all the buzz about chroming the new '08 Split Spokes:

Your answer above contradicts the post you originally made.

You said...."There is a reason GM doesn't offer Chrome on all wheel styles". Please tell me the reason.........

Are you saying a wheel on a base 430 HP Corvette needs to be stronger then a wheel on a Z06 or ZR1 so they only offer it painted?

Seems to me that a wheel on a 638 HP car that can hit 1.13g's needs a stronger wheel then a car with 430 HP that hits .92g's. Yet GM offers a chrome wheel on the 638 Hp version on the C6.

PS- All wheels have to meet DOT requirements.

No contradiction. Part of the reason is the style of the wheel, some designs would be very labor intensive to polish prior to chroming.

Another part of the reason; I'm reasonably sure that the bean counters at GM have looked at what alloys of Aluminum will Electochrome and which ones would cause a hydrgen embrittlement problem. Cheaper material, cheaper tooling, cheaper handling = a cheaper wheel. In '08 a 5 spoke Chrome was an $1800 option, the split spokes were standard (no extra charge). $450 a wheel, Chrome just for profit?

I didn't say anything about the strength of a wheel for different models of Corvette. The Z06 and ZR1 wheel styles are exclusive to those models and C6 wheels wouldn't fit correctly anyway. If you want to widen the C6 wheels and run track days be my guest, I wouldn't trust stock C6 wheels at the stresses a Z06 or ZR1 would run.

You did notice that the '08 split spoke has never been available in Chrome? We'll never know if it was because of the cost to polish and chrome or if it was because the alloy would be affected by Hydrogen embrittlement and be weaker.

once again, Rick, that is a great thread outlining the differences in wheels. I even see our old buddy, "Modshack" showing the difference in wheels by pics. too bad steve eventually sold his C6.

Ah! I didn't know he sold it but figured he did since he hasn't been around in a long time. Too bad, he contributed a lot here.

Hal, you may be correct. I was relying on my 45 year old degree in metallurgy, but that was so long ago we only had stone, bronze and iron. Google does show some references to it, as you say. On the other hand Wikipedia says "tests have shown that austenitic stainless steels, aluminum (including alloys), copper (including alloys, e.g. beryllium copper) are not susceptible to hydrogen embrittlement" (http://en.wikipedia.org/wiki/Hydrogen_embrittlement). Perhaps part of the problem is that it can be hard to detect.

"While hydrogen can invade most metals, certain metals and alloys are known to be more susceptible to hydrogen embrittlement, namely magnetic steel, titanium, and nickel. In contrast, copper, aluminum, and stainless steel are least impacted."

http://www.wisegeek.com/what-is-hydr...rittlement.htm

"Hydrogen embrittlement does not affect all metallic materials equally. The most vulnerable are high-strength steels, titanium alloys and aluminum alloys."

http://techplate.com/hydrogenembrittlement.html

I found several referances that say the same thing.
