Topic: eletrolytic corrosion resistance over aluminum substrate surface

Hi! How to get an optimal corrosion resistance plating over aluminum substrate surface using electroplating methods, which metal and methos of work use in madding the alloys multiple layers for get the corrosion resistance??

Re: eletrolytic corrosion resistance over aluminum substrate surface

In my experience with decorative applications and aluminum wheel plating, The typical approach I used was this:

Non-etch soak

Etch

desmut

etch

desmut

zincate

zincate strip

zincate

sulfamate nickel strike

semibright nickel

high sulfur nickel

bright nickel

micro porous nickel

chrome


You can remove the high sulfur and micro porous nickels for a more "typical" cycle.
