Where pump parts are fabricated by welding from nickel aluminum bronze plate, there is a serious risk of selective phase corrosion (dealuminification) in the heat effected zone of the weld. This can crack if stressed, e.g., by water hammer effects. Pump Impellers
Etching metal using the salt water method is pretty easy to do.
COMPATIBILITY CHEMICAL COMPATIBILITY Chemicial Compatibility Guide The following information is intended to be used as a general guideline for pump material selection.

Preparation of 3-mercaptopropyl)trimethoxylsilane (PropS-SH) film on brass surface and its corrosion resistance performance were investigated by surface energy analysis, Fourier t
Heavy metal pollution in water is very high in areas where mining, smelters, metal processing refineries, wood preservation, and paper processing facilities are located. Human exposure to heavy metals as well as public concern for the associated health risks have both risen dramatically as a result of an exponential increase of their use in ...

and decarboxylation of glucuronic acid have been published (2). Bornyl glucuronide was obtained from the urine of borneol-fed guinea pigs as the zinc salt (ZBG) and its chemical identity was established by elementary analysis and by the Dische calorimetric test. CJ2HS001,Zn.2H20. Calculated.
Why does zinc react with salt water? originally, i did an experiment by wrapping zinc wire around an iron nail to stop it from rustin(in other words, galvanising)and put it in salt water and pbserve for a few days, it didn't corrode but the zinc reacted to the salt water.
• Coolant is water only • Source water does not meet engine manufacturer specifications • Ethylene glycol is beginning to degrade or coolant is burnt • Combustion gas blow-by from cracked head, head gasket failure, perforated hole in cylinder liner, etc… • Acid type cleaner used and not flushed thoroughly POTENTIAL DAMAGE • Corrosion on iron components as well as other metals in the system

Weekly Salt Water Pool Maintenance. Your weekly salt water pool maintenance routine will depend on pool usage and environmental factors. In addition to spot cleaning with a skimmer net, vacuuming and emptying the pool pump basket the most common thing you'll need to do is balance the water chemistry.
During operation in water, especially salt water, the oxidation forms a weak electrical current, which may corrode the hull and engine parts. Since zinc is easily oxidized in the presence of this electrical current, it "sacrifices" itself by corroding quickly, consuming all of the electrical imbalance in the ship.
The acid water goes in, coming out it's nice, neutral water. For some folks, they say that after a week or 2 the blue stains stopped. They can have a pretty strong and immediate effect of slowing down the corrosion in the pipes. Neutralize Acidic Well Water. We usually recommend a backwash neutralizer to neutralize acidic well water.

MLPC International (Arkema Group) is supplier for Dibenzyldithiocarbamic acid zinc salt.
used to sterilize potable water systems is discussed. Case histories of chlorine as an oxidant and biocide on corrosion behavior are given. Guidelines are developed for alloy use in fresh waters. Chlorine is the primary oxidant, other than oxygen (aeration), used in treating cooling water, potable and waste water, and water used in swimming pools.

Marine Biofouling. It is both the inherent resistance to biofouler attachment and the poor adherence of the occasional biofouler able to attach that made copper so useful as hull sheathing for sailing vessels and copper-nickel so useful for the piping, water boxes, and other components of marine cooling water systems.
Zinc (Zn) and Lead (Pb) are us ually called gunmetal ("rødmet-all"). Leaded gunmetals with high tin content (at least 5% Sn) such as RG5 are comparatively resistant to corrosion in sea wa-ter provided the water is pure. In sulphide polluted sea water, alloys with higher content of Sn, for inst. RG7 and RG10, are quite resistant. 3.1.4 Aluminiumbronze

As Ed said there are a lot of different materials classified as "Brass", eg Naval brass, Aluminum brass.. that are used in Sea Water service and perform well. Usually alloys with higher Zn content are more susceptible to dezincification and can be suppressed by the presence of small amount of arsenic and other elements.
Mechanical Properties*. Resistant to pure steam. Carbon dixide, dissolved oxygen can increase corrosion. Resistant to ammonia attack. Water, Potable Excellent Corrosion affected by water chemistry (mineral content, acidity) system design and fabrication. Free carbon dioxide can cause pitting in cold water. Pitting in hot water caused by cathodic deposits.
