Solution - Rust occurred after plating (metallization) on iron

Company LL had a trouble with a rust occurred after plating on iron. They could not solve this
by adding under layer plating and change the specifications by some other company. Then they asked our help. We observed and analyzed the rusty surface with EDS (Energy Dispersive X-ray Spectrometry), we found the particles derived from the barrel polishing abrasives.
We proposed the change from the barrel polishing process to our pretreatment on the ground, because the media attached to the material affects the rust after plating. Finally we were able to prevent the rust.
