Title:
SULFUR TREATMENT FOR COPPER ZINC ALLOYS
Document Type and Number:
WIPO Patent Application WO/2012/148912
Kind Code:
A4
Abstract:
Brass components exhibiting excellent resistance to dezincification corrosion and stress corrosion cracking are prepared without, or with a reduced need for, corrosion inhibiting additives by developing a metal-sulfide rich barrier layer at the surfaces of the component. Brass components treated as disclosed exhibit corrosion resistance as determined by standardized testing that yields dezincification penetration less than 200 microns in depth and exhibits no stress corrosion cracking.
