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 کاملDrugs/Antibiotics as potential corrosion inhibitors for Metals - A Review
Corrosion protection of metals and alloys is a prime activity of technical, economic, environmental, and aesthetical significance. The use of inhibitors is one of the best choice of combating metals and alloys against detoriation against environmental impact. The toxicity of organic and inorganic corrosion inhibitors to the environment has provoked the search for ecofriendly corrosion inhibitor...
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 کاملMeasuring of Residual Stress in TIG Welding of the 304 Stainless Steel by Ultrasonic Method
In this research, the effect of different welding parameters on residual stress and microstructure of the weld region, as well as the comparison of two methods of measuring residual stress using critical fracture longitudinal wave method and preformation method have been investigated. For this purpose, the taguchi DOE methodology is used as a statistical method to optimize four parameters of pu...
متن کاملHigh 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...
