A chromium-free plating system that reduces costs by up to 30% while retaining excellent corrosion protection and low friction coefficients has reportedly been developed b y Doerken Corp. USA, Ann Arbor, Mich. Called Delta-Protekt KL 105, the zinc-flake coating is applied via dip-spin, dip-drain, spray, or spin-coating.

Corrosion protection is established by sacrificial corrosion of zinc, and is enhanced by a barrier effect caused by overlapping ...
