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...
متن کاملA Short Introduction to Corrosion and Its Control Corrosion of Metals and Its Prevention What Is Corrosion
The consequences of corrosion are many and varied and the effects of these on the safe, reliable and efficient operation of equipment or structures are often more serious than the simple loss of a mass of metal. Failures of various kinds and the need for expensive replacements may occur even though the amount of metal destroyed is quite small. Some of the major harmful effects of corrosion can ...
متن کاملCorrosion 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...
متن کاملAnomalous dissolution of metals and chemical corrosion
An overview is given of the anomalous behavior of some metals, in particular Fe and Cr, in acidic aqueous solutions during anodic dissolution. The anomaly is recognizable by the fact that during anodic dissolution more material dissolves than would be expected from the Faraday law with the use of the expected valence of the formed ions. Mechanical disintegration, gas bubble blocking, hydrogen e...
متن کاملCorrosion Prevention
Speculating about where the future of the field of corrosion prevention, detection, and rehabilitation might lead is interesting—but not without risk. We all are aware of the revolution in electronics, particularly digital electronics, and information science during the past 20 years. We also should recognize that materials science and technology have undergone a major revolution, bringing us n...
