Corrosion Behaviour of Copper Alloy in 3%NaCl Aqueous Solution

Corrosion Behaviour of NIMONIC-90 Alloy

Investigations were conducted on hot corrosion of Nickel base, NIMONIC-90 at 675°C and 725°C. The tests were carried out on small test coupons coated with a chemical containing Sodium sulphate and Sodium Vanadate which is representative of the corrosive deposit that usually forms during service in the coal fired boiler and the likes operating in marine atmospheres. Corrosion rates were measured...

Effect of Hydrogen on Corrosion and Stress Corrosion Cracking of AZ91 Alloy in Aqueous Solutions

The effect of hydrogen on the corrosion and stress corrosion cracking of the magnesium AZ91 alloy has been investigated in aqueous solutions. Hydrogen produced by corrosion in water diffuses into, and reacts with the Mg matrix to form hydride. Some of the hydrogen accumulates at hydride/Mg matrix (or secondary phase) interfaces as a consequence of slow hydride formation and the incompatibility ...

Corrosion Performance of Copper - Diamond Composites in Different Aqueous Solutions

In the present work copper/diamond composites, such as (Cu-10 Vf % diamond uncoated, Cu-30 Vf % diamond uncoated, Cu-10 Vf % diamond coated NiCrB and Cu-30 Vf % coated NiCrB) as heat sink materials have been fabricated using powder metallurgy and electroless techniques. The copper powder used in this study has been fabricated using electroless technique and the diamond powder was electroless co...

Developing of Corrosion Resistance Nano Copper Oxide Coating on Copper using Anodization in Oxalate solution

Copper alloys are widely used in the manufacturing of heat transfer applications, this due to their excellent heat transfer properties. Copper contamination is one of the serious industrial problems in the boiler feed water system. This contamination commonly resulted from copper corrosion reactions in boiler feed water environment. The best way to reduce the copper contamination is by improvin...
