Surfaces of Corrosion-Resistant Metals in Wet Corrosion Environments.

High Strength Corrosion Resistant Metals

There are a number of ways to improve the corrosion and abrasion resistance of metals, including alloying, anodizing, nitriding and application of protective thin films. Alloying involves generating a binary phase diagram to determine the optimum composition and temperature dependence. For example, copper alloys known as “bronzes” offer high strength, abrasion resistance and high temperature co...

VIII-Metals-J-Corrosion protection-1_ CORROSION PROTECTION OF METALS

Nearly all metals, with the exception of gold and platinum, will corrode in an oxidising environment forming compounds such as oxides, hydroxides and sulphides. The degradation of metals by corrosion is a universal reaction, caused by the simple fact that the oxide of a metal has a much lower energy than the metal itself. Hence there is a strong driving force for the oxidation of metals. For ex...

Corrosion of Metals and Alloys

Although all metals are subjected to the general oxidation reaction (I), the tendencies to ionize differ from metal to metal. When two metals are exposed to an aquenous environment and release electrons according to reaction (I) , an electric potential is induced the standard value of which can be measured when the metals are in 1-molar solutions of their own salts at a predetermined temperatur...
