hi everyone does anyone know what does triple chome mean.do it mean copper,broze and chrome.or.do it mean copper,bronze,chrome,chome,and chrome.or do it mean chrome,chrome and chrome,which one is correct is the triple chrome term just a sales pitch and all wheels are chromed the same process.thanks i need all the info i can get . :banghead:

 

I think you'll have to get a manufacturer to tell you what thickness is applied.

Where I work, we're always sending parts out for high-tech coatings. Hard chrome is one of them. You can specify all kinds of thicknesses, from 0.0002" flash chrome, up to .015" or more.

Triple chrome is a funny statement, because putting it in the tank three times doesn't make sense, because if you want more chrome, you just leave it in the tank longer.

 

thanks for the info :)

 

Triple Chrome Plating

Q. I heard someone use the term "triple chrome plated". They explained that the steel part is dipped three separate times in a solution before being polished. They claim that the chrome comes out thicker. Is this possible?

A. Due to the low efficiency, slow plating speed and tendency for chromium to produce rough deposits with heavy buildups, platers will often plate a part requiring a thick chromium coating over more than one plating cycle. It is fairly common to grind or polish the chrome after the first layer, then plate "chrome-on-chrome" as needed to get the desired dimensions. A special activation technique is needed to accomplish a satisfactory bond between the two chromium layers.

The polishing step after the first layer will result in smoother subsequent deposits. It can also improve the corrosion resistance of the final product significantly, because it creates a smeared boundary between the microcracks in the first and second layers of chromium. Generally, there is no need to polish between any subsequent layers.

Most parts are plated with chromium using a single plating cycle. This may not be possible if the required chromium thickness is too great, or if the plater cannot accurately estimate the plating rate of deposition and plating time. Platers will often pull a part from the chrome tank, measure it quickly, then immediately return it to the tank and resume plating if it needs more thickness. This process may be performed more than once. If the part is not polished in between, the part may have a rougher deposit, even it receives the desired final thickness of chromium. Also, this procedure may result in a weak bond with the potential for peeled chrome.

 

Triple chrome plating is basically what you were thinking. First, the part is stripped, cleaned and washed in an acid bath. Then, it is electroplated with a layer of copper. Imperfections in the finish are ground and filled, then hit with a copper bath again. If the part finish is smooth, then it gets a bath of nickle. Minor imperfections are buffed out, and then the part will get it's final bath in chromium. The 3 step plating gives the part better depth and luster, as well as better adhesion and durability. The real key is the plater takes time between each layer to buff out any imperfections. It is not uncommon to get 2 or 3 copper dips until the finish is perfect. Only then will you get a flaw free finish. If you just dip a part in chromium, the imperfections will be visible under the chrome, and it will peel off or rust quickly. Find a reputable shop to do your plating. You get what you pay for. Make sure to ask the wheel manufacturer how long their chrome warranty is.

 

thanks you were very helpful :)
