Q. Hi my name is Greg Mckeown; we produce parts for the rail industry and we use a material called Remko which has magnetic properties.
These parts are zinc and trivalent plated by an outside source but we are having issues with adhesion, with the plating flaking off. Any ideas what may be causing this?

A. Hi Greg. Can you point us to where we can read about Remko? I am not familiar with it, but if it's high in nickel it might need Wood's Nickel Strike before plating.

A. Greg,

First you have to find out if flaking problem is from base metal to zinc or zinc to trivalent plate; if base metal then a cleaning issue.

A. I see now that Remko is a trade name for materials including Remko HP high purity iron (DTD 5102). Plating onto Remko HP would not be plating onto cast iron but onto high purity steel. Therefore I would not expect this to be a difficult-to-plate material, and would share Popat's opinion that poor cleaning/activation may be responsible for poor adhesion of the zinc plating.
