釹鐵硼磁鐵 燒結:
燒結釹鐵硼磁鐵是一種有色磁性材料,由于其具有優異的磁性能、耐熱性和耐腐蝕性,被廣泛應用于電機、變頻器、空調、電視、電腦和其他電子設備中。燒結釹鐵硼磁鐵的制備方法包括燒結和氧化燒結。
燒結法——燒結法的基本原理是將鐵粉、釹粉、硼粉和其他添加劑混合,放入高溫灶中,在高溫下燒結成磁性材料。燒結過程中,釹粉在燒結溫度范圍內熔融,分散在鐵粉中,形成磁性材料。燒結后的釹鐵硼磁鐵具有較高的磁性能,但有一定的燒結溫度要求,燒結溫度過高會導致鐵粉形成多孔結構、磁性損失和燒結塊脆性。
氧化燒結法——氧化燒結法是在燒結過程中,加入適量的氧化劑,在氧化劑的作用下,形成一層氧化膜,使燒結后的釹鐵硼磁鐵表面光潔,具有良好的磁性能。氧化燒結法可以提高燒結塊的強度,降低燒結溫度,減少燒結時間,節約能源。
Sintered neodymium-iron-boron magnet is a kind of colored magnetic material, which is widely used in motors, frequency converters, air conditioners, televisions, computers and other electronic devices because of its excellent magnetic properties, heat resistance and corrosion resistance. The preparation of sintered neodymium-iron-boron magnet includes sintering and oxidation sintering.
Sintering method - the basic principle of sintering method is to mix iron powder, neodymium powder, boron powder and other additives into a high-temperature furnace and sinter them into magnetic materials at high temperature. During sintering, neodymium powder melts and disperses in iron powder to form magnetic materials within the sintering temperature range. The sintered neodymium-iron-boron magnet has high magnetic properties, but there is a certain sintering temperature requirement. If the sintering temperature is too high, the iron powder will form a porous structure, magnetic loss and sintered block brittleness.
Oxidation sintering method - oxidation sintering method is to add a proper amount of oxidant in the sintering process, and under the action of the oxidant, a oxide film is formed on the surface of the sintered neodymium-iron-boron magnet, which makes the surface of the sintered neodymium-iron-boron magnet smooth and has good magnetic properties. Oxidation sintering method can improve the strength of sintered block, reduce sintering temperature, reduce sintering time and save energy.
