Uhlig [4] have more or less classified the corrosion types as: (1) General Corrosion or Uniform Attack, (2) Pitting, Fretting, Cavitation-erosion, (3) Dealloying Dezincification and Parting, (4) Intergranular corrosion, (5) Cracking.
Marshakov, "Electrochemical studies of the kinetics and mechanism of brass dezincification," Electrochimica Acta, vol.
10), by means of x-ray photo-electron spectrometry (XPS), that a Cu-Zn-Co ternary alloy exhibits much slower dezincification than normal brass.
Zinc generally goes into the domestic supply from corrosion of galvanized iron and dezincification of brass.
The major sources of water contamination of Zn are from industrial wastes, deterioration of galvanized iron and dezincification of brass etc.
With CuZn, the dezincification process [18] where Zn segregates to the surface of CuZn when heated to below its melting point of 914[degrees]C is utilized.
All Acvatix ball valves are made of 100 per cent DZR (dezincification resistant) brass and the balls are chrome-plated and polished.
"We showed how the difference between forward and reverse current flows allowed determination of the surface copper-to-zinc ratio and hence the degree of dezincification of the brass.
Zinga has been used to galvanise aluminium boat superstructures and has even been used to coat brass propellers to stop "dezincification" of the brass in seawater where the zinc element of the alloy dissolves in seawater to protect the stainless steel prop-shaft etc and the remaining copper is naturally soft and begins to break up.
These brass tubes, 70% copper, 30% zinc, suffered from "dezincification," which is a process where the zinc is preferentially removed by corrosion.
