chrome embrittlement

wasnt sure where this really belonged ,but this area made sense anyway.
since a certain kid from the new york area brought this subject up again to start crap in another post i figured id start a new post about it and differant cures for it for everybody to decide for themselves rochesterovernightplating.com/serv04.htm

www.springerlink.com/index/L532061V336P2K83.pdf another cause of embrittlement,maybe we should sto welding and start gluing parts together B)

We buy a ton of fasteners and the wholesaler's catalog is littered with warnings around hydrogen embrittlement. We can't even buy chromed bolts from any of the mainstream fastener companies.

I'm no expert on the subject, but I remember being told by a race bike frame maker never to chrome a frame.

My understanding on Hydrogen Enbrittlement is that the problem can be resolved by baking the part at 350F for 60 minutes. This releases the build up of the gas during the plating process.

Please give link to post. You've peeked my curiosity.

This is the original discussion I referenced in another thread

yeah did ya notice the part in the first post from a year and a half ago where BOEING calls for baking parts in an oven by their specs?

yeah, yeah; but they have specs... I have been reading as well

depth of chrome, layers of chrome shape or piece being chromed and more factors are used by engineers to decide what temperature and for how long.

Using toothless Joe's 30 minutes at 400* recipe on everything from triple trees to frames to spokes is just asking for trouble. also has old toothless Joe ever done any kind of testing to find out how strong the parts that were leaving his shop were? How is he sure he has effectively combated the effects of the chroming process?



Point being re-chroming spokes even if you bake them is just as unsafe (with no testing) as running 200psi through a tube rated for 400 psi (yes air compresses, but pressure is pressure). Neither one should be considered the correct method, but both will get the job done if the offending party is AWARE of the risks (I wont ride re-chromed spokes but if a grown ass man wants to shake and bake them have at it!)

and how do you know what the process was when they were origionally plated?

I don't but I trust Kawasaki did a test or two to make sure the spokes would do the job.

how about the bolts holding on your handle bars and fork legs and all those other shiny parts on your bike? does kawasaki have some sort of patent on safe chrome plating,or was all that stuff subbed out to the cheapest vendor they could lay their hands on to supply enough materials to build bikes with?
how about all those fancy chrome bumpers that have been slapped on cars and trucks since the dawn of time? are they just time bombs waiting to explode going down the road? how about all those old cragar wheels people have been running since the 60s? :woohoo:
