chrome vs pvd coating

Hello everyone,

I would like some testimony on bright pvd wheels vs chrome wheels as far as durability, shine, ease of clean etc... Pro's and con's for both please. Anyone have any experience with bright pvd wheels?

Thanks in advance

Laurie

Re: chrome vs pvd coating

I work for the world's largest PVD coater. Nooooo waaaay would I get PVD coated wheels. Yeah, it can be a decorative coating but that's on display parts and pieces, firearms, trophies, etc. I watched a video of how one of these companies does this. Spray a grey primer on and let it cure before PVD coating? No way. PVD coating is only a few microns thick. Any thicker and it can delaminate. PVD coating must have a clean and etched surface for proper adhesion. When we etch tools in our coating vessels, we actually burn a molecular layer off of the tools so the PVD coating adheres properly. Any oil-based solvent like WD-40 will lift PVD coating right off the part. Takes a while to do it but it will do it but it will happen. PVD coating is a line of sight process that occurs in a vaccuum greater than outer space. It would be next to impossible to get a uniform coating thickness in all the nooks and crannies of a complex wheel. I wouldn't do it.

Many of the newer cars today have had PVD coated wheels - and other parts - for years now
Yes, they 'can' peel, flake, discolor and otherwise fail - but so can chrome.
Either process requires complete and proper cleaning and prep to get reliable results.

I think the answer to your question lies in what you want and how you intend to use it.
If you want a 'color' then your almost stuck with a PVD or other sprayed coating technology.
If you just want some 'bling' then chrome is time proven technology to get there - if done correctly ...

Oh, you must work in Clinton Township Chet

Re: chrome vs pvd coating

Actually, John, I work everywhere but I have been seen a time or two in Clinton Twp or Wixom in Michigan. We have 9 centers in Canada and the U.S. with two more being built. I go around the country as an application engineer conducting coating tests and making recommendations as to what coating is best for machining auto engine parts, diesel truck engine parts, jet engine parts, etc.

Shaky Ground

How are you people? Standing on shakiy ground here, i do not have a camarro but I do have a car that is a thrill to drive just as I hope all your cars are for you. Anywy, I am trying to gather up some info on this new chrome plating being performed on wheels. Being torn between putting original type wheels or going modern with the chrome? Anyone out there have any expeience with the new wheels? I believe they call it PVD- google it. On second thought don't - you will be more confused then when you started. Chrome plating done wll vs. PVD chrome plating done well - who wins?
