Caustic Effect On Zinc-Coated Steel
Can you tell me whether caustic soda will dissolve the zinc coating on zinc-coated steel?
Read MoreTighter Tolerances
We have a number of jobs that require making steel parts with very tight tolerances on the fit. We are thinking that zinc plating/chemical conversion coating might not be the best solution for us. Are there other materials out there that might give us more consistency on our tolerances and thickness?
Read MoreCopper Plateback
We have a rack line where we run our zinc and tin plating, and we are noticing when soaking copper parts, in our alkaline soak cleaner, that our steel parts will acquire a dark film on them, when removed from the soak, to go into the electrocleaner. What would be causing this?

Despite concerns about cobalt and chromium coating debris on metal hip replacements, noted dermatologist says there is little risk that patients will have a skin reaction or joint pain from the devices.
Read MoreCobalt-Free Zinc and Zinc-Alloy Passivation
This article will detail an alternative to cobalt-containing trivalent chromium passivation. Field results from this unique passivate system have demonstrated comparable corrosion protection to existing cobalt-containing Cr(III)-based passivates. The new system is easy to handle and offers a broad operation range. The performance, appearance and passivation mechanism, as well as some limitations, will be discussed.

The following article highlights the introduction of a gold-iron hard gold electrolyte as an anti-allergic alternative to replace cobalt- and nickel-containing hard gold deposits.
Read MoreElectroless Nickel Duplex Coatings Using RoHS-Compliant Systems
Duplex coatings can offer corrosion and wear resistance that exceed those of conventional electroless nickel (EN) deposits for specialty applications. Duplex coatings consisting of a high-phosphorus EN or a new ternary alloy underlayer and an upper layer of low-, low/mid- or mid-phosphorus electroless nickel were investigated. Wear, adhesion and corrosion resistance properties for numerous combinations of EN duplex coatings are presented here, both as-plated and after heat-treatment. Duplex coating results are compared with single layer EN deposits.
