The oxidation of superalloys is a fascinating scientific process that involves the reaction of an advanced material with an oxidizing medium to form oxides. When we talk about high temperatures, we are usually referring to environments where oxidation reactions accelerate dramatically under such conditions. This process is destructive to high-temperature alloy parts, and the importance of studying it is self-evident. Understanding this process is critical for researchers who are committed to the proper use of superalloys, the improvement of old alloys, and the development of new alloys.
## What is the oxidation of high temperature alloys?
To understand the oxidation of high-temperature alloys, we first need to understand the concept of high-temperature oxidation of metals. This word has a narrow sense and a broad sense. A narrow interpretation refers to the process in which metal reacts with oxygen at high temperatures to form metal oxides. The broad explanation is more complicated. It refers to the process in which atoms, atomic groups or ions that make up a material lose electrons at high temperatures.
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. For example, some parts of aerospace engines need to be heat treated in air, low vacuum, or argon containing trace amounts of oxygen. The oxidation of these parts belongs to high-temperature oxidation in a narrow sense. In addition to the reaction between metal and oxygen, generalized high-temperature oxidation also includes high-temperature vulcanization, high-temperature halogenation, high-temperature carbonization, mixed gas oxidation and hot corrosion.
## Oxidation Research of High Temperature Alloys
The chemical composition of high-temperature alloys is complex, with more than ten main alloying elements, which makes the oxidation process very complicated. To understand this process, researchers broke it down into two main parts: thermodynamics and kinetics. Thermodynamic analysis can help us judge and understand the possibility of oxidation reactions and the role of alloy elements, while kinetic studies can help us determine the speed and law of oxidation reactions, as well as analyze the control mechanism of oxidation reactions.
