Metal thermochromic phenomenon and its application in magnetic polishing machine

Metal thermochromic phenomenon and its application in magnetic polishing machine
Metal thermochromic phenomenon refers to the phenomenon that the surface color of metal changes under high temperature environment. This phenomenon is widely used in aviation, automobile, construction and other fields. As a new type of surface treatment equipment, magnetic polishing machine uses the principle of metal thermochromic to achieve efficient and environmentally friendly polishing of metal surface. This article will discuss the phenomenon of metal thermochromic and its application in magnetic polishing machine.

Metal thermochromic phenomenon
The occurrence of metal thermochromic phenomenon is mainly related to the structure and composition of the oxide film on the metal surface. When the metal comes into contact with oxygen under high temperature environment, a layer of oxide film will form on the surface. This oxide film has a certain protective effect and can prevent the metal from continuing to oxidize. However, the structure and composition of the oxide film will change with the increase of temperature, resulting in the change of metal surface color.
Metal thermochromic phenomenon has the following characteristics:
Reversibility: Metal thermochromic phenomenon is reversible within a certain temperature range, that is, when the temperature is reduced, the color of the metal surface can be restored to its original state.
Heredity: The phenomenon of metal thermal discoloration has a certain degree of heredity, that is, the color change produced by the metal in a high temperature environment will remain in the subsequent processing process.
Stability: The color produced by the phenomenon of metal thermal discoloration has a high stability and is not easy to fade.

Principle and advantages of magnetic polishing machine
The magnetic polishing machine is a device that uses the action of a magnetic field to achieve metal surface polishing. The principle is as follows: the metal to be polished is placed in a magnetic field, and a magnetic fluid is generated on the metal surface. The abrasive particles in the magnetic fluid grind the metal surface under the action of the magnetic field force, thereby achieving a polishing effect.
The magnetic polishing machine has the following advantages:
High efficiency: The magnetic polishing machine has a fast polishing speed and high efficiency, and is suitable for mass production.
High precision: The magnetic polishing machine can achieve micron-level polishing accuracy to meet the needs of high-precision processing.
Environmental protection: The magnetic polishing machine uses water-based grinding fluid, which is pollution-free and meets the requirements of green production.
Strong adaptability: The magnetic polishing machine is suitable for various metal materials, such as stainless steel, copper, aluminum, etc.

Application of metal thermochromism in magnetic polishing machine
The application of metal thermochromism in magnetic polishing machine is mainly reflected in the following aspects:
Polishing effect monitoring: By observing the change of metal surface color, the polishing effect can be monitored in real time to ensure the polishing quality.
Optimize polishing process: According to the law of metal thermochromism, adjust the polishing temperature, time and other parameters to achieve the best polishing effect.
Protective effect: The oxide film produced by metal thermochromism has a certain protective effect, which can prevent the metal from continuing to oxidize during the polishing process.
Aesthetics: The metal thermochromism phenomenon can make the metal surface present different colors and improve the appearance quality of the product.
In short, the application of metal thermochromism in magnetic polishing machine is of great significance. Through the study of metal thermochromism, the polishing effect of magnetic polishing machine can be improved, providing strong support for my country’s metal surface treatment industry. At the same time, the application of metal thermochromism in other fields also has broad prospects and deserves further discussion.
