The oxidation of high-temperature alloys refers to the process in which high-temperature alloys react with oxidizing media at high temperatures to form oxides. At high temperatures, the oxidation reaction accelerates rapidly and is destructive to high-temperature alloy parts. Therefore, it is very necessary to study and master the oxidation laws of high-temperature alloys.
The definition of high-temperature metal oxidation has a narrow sense and a broad sense. The oxidation reaction in the narrow sense is the most basic and common, because oxygen is the most common gas medium in nature and industrial environments, and air and water vapor can be found everywhere. Some parts of aero-engines need to be heat treated in air, low vacuum or argon gas containing trace amounts of oxygen. Compressor parts of aero-engines or gas turbines, re-entry shuttle spacecraft, etc. must withstand the effects of high-temperature oxidizing environments. The effects of these parts Oxidation belongs to high temperature oxidation in a narrow sense.
The chemical composition of high-temperature alloys is complex, with more than ten main alloying elements, so the oxidation process is very complicated. The study of the oxidation process usually includes two aspects: thermodynamics and kinetics. Through thermodynamic analysis, the possibility of oxidation reaction and the role of alloy elements can be judged and understood. Determine the speed of the oxidation reaction, the rules of the oxidation reaction, and analyze the control mechanism of the oxidation reaction through kinetic studies.
During the oxidation process of high-temperature alloys, an oxide film is formed on the surface of the alloy. This oxide film can play a protective role and prevent further erosion of the alloy by high temperature environments. However, the formation of oxide films can also affect the properties of the alloy. Therefore, studying the formation and properties of oxide films is of great significance for the application of high-temperature alloys.
In short, the oxidation research of high-temperature alloys is of great significance for the correct use of high-temperature alloys, the improvement of old alloys, and the development of new alloys.
