Ok I have a nephew that works at a major tool manufacturer that does nickle plating. He is allowed to run just about anything through he wants, and has offered to do my stock steel ATV wheels. He claims that alot of guys he works with have done every type of wheel from race to street with no known problems.

I have heard of possible problems with stress related parts failing due to some sort of depletion in the metal from plating? I believe this was with chrome plating though? So any metallurgy experts or anyone in the know before I possibly ruin a stock set of wheels?

Any and all help appreciated

Thanks

IAJack

I have worked in a Plating shop for 13 years. I see no reason why you shouldn't be able to Strip the current finish, then bright nickel plate the wheels safely. ride'em hard Polcat

IAJack, you are correct that certain types of plating,mainly hard chrome,can cause hydrogen embrittlement which causes cracking in stressed areas.This trapped hydogen can be removed by a post heating of the parts. If the nickel plating is a electroless type you do not have to worry.

polcat, others....

Thanks for your reply. As in your answer and others I have pretty much decided to have em done. Alot of guys in the business like you I have talked to say failures are pretty rare, and are mostly due to high strength steels and high stress parts. Although wheels are under alot of pressure, I really still wouldn't call em a high stress part like an engine blower or heads.

Also Do you bake any of your parts afterwards or anything special?

Thanks again BTT

Hydrogen embrittlement is more prevalent in heat treated material. As the other fellow stated electroless plating does not induce hydrogen embrittlement, but many plating processes are electric current aided. The baking process to prevent this problem is usually around 375 degrees from 4-10 hrs. immediately after plating the parts. As stated before though hyrogen embrittlement is not a problem usually associated with non-heat treated parts. With your rims I do not see any problems.
