Conforming Anodes for Hard Chrome Plating
What wuld be the etching time for rods? Does it vary based on the size of the rod?
Also, what, precisely, are conforming anodes?
The time and power levels during the
activation preplate procedure determine the degree of etch. The
of reverse etch required for parts varies significantly, depending upon
- Substrate material
- Heat treatments applied.
- Carbon content of
I can't define reverse etch parameters
without additional part information, and then, it would require that I
more time than this "Ask The Expert" forum permits.
Regarding conforming anodes, I have
lot of people how to fabricate them. The process involves melting ingot
lead-alloy, casting "gridmats", forming the gridmats into the
curvature or shape and welding the gridmats together to build
basket. Attachment leads are
then welded to the anode body to form a completed anode.
These anodes are more efficient than
plate parts at higher current densities and can help to achieve deposits
are more uniform.
