NDT thickness of Zn coating
NDT thickness of Zn coating
(OP)
Dear all,
How can I determine thickness of elctroZn plating on iron substrate without cutting the piece?
Alcometer is out of the question I guess since Zn is conductive.
Xray? anything else?
Thansk,
Herc.

Second common method is using a weight difference - weigh the item, strip off the Zn with inhibited HCl, reweigh and calculate using surface area and density of Zn. More commonly used for small or irregular items which are difficult to measure with a magnetic thickness gage.
