Institute of rare Earth Magnetic Materials and Devices

Cooperating with the National Engineering Technology Research Center for efficient Development and Utilization of Ionic rare Earth Resources, Jiangxi key Laboratory of rare Earth Magnetic Materials and Devices, Ganzhou rare Earth permanent Magnet material Service characteristics and Application Development Engineering Technology Research Center, the Institute of rare Earth Magnetic Materials and Devices (abbreviated as " Magnetic Institute") is founded by Jiangxi University of Science and Technology in 2014. It is a scientific research base to train talents of rare earth magnetic materials and to meet the needs of national economic development and the revitalization strategy of the Soviet area. We mainly engaged in rare earth permanent magnets, magnetic refrigeration, magnetic nano-wave-absorbing materials and other research fields.

Since its establishment, the Institute has adhered to the concept of serving the local economic of Jiangxi Province and has carried out multi-faceted and multi-level cooperation with local enterprises along the path of "market orientation-industrial objectives-technical barriers-R & D needs". To solve the technology problem as the goal and promote the development of industrialization, we take the road of the combination of industry, research and application. The Institute has a series of advanced equipment for magnetic material preparation, microstructure analysis, magnetoelectric performance testing and service characteristic evaluation, as well as 3 kg and 50kg sintered NdFeB industrial preparation production lines, with a total value of nearly 20 million RMB. There is a high-level and efficient R & D team with 14 researchers, nearly 60 doctoral and postgraduate students (including foreign students) and more than 10 undergraduates.

The Institute pays attention to talents training and is committed to train more high-quality talents for industries. Up to now, more than 10 graduate students successfully graduated from Jiangxi University of Science and Technology are now working and awarded by these rare earth permanent magnet enterprises such as Jinli Magnet (JLMAG), Gold dragon rare-earth based on Changting, Fujian province, Ningbo Yunsheng Co.Ltd and so on. We also attach importance to communicate with other universities and limitations, and establish relationship with the University of Idaho based on the United States, Air University located in Pakistan, Central Iron and Steel Research Institute, South China University of Technology in project cooperation, personnel training and team building. In order to contact and communicate with enterprises related to magnetic materials, we have signed cooperation framework agreements with more than 20 enterprises to jointly build academician workstations, joint research and development centers, test bases, and so on. Good economic and social benefits help us achieve a lot in new energy vehicles, wind power generation, maglev rail transit rare earth permanent magnet materials.

Main research fields and s achievements of the laboratory

1. Preparation technology of grain boundary diffusion of sintered permanent magnets with high temperature stability. The element characteristics are used to optimize the micro-morphology and element distribution of the main phase of NdFeB magnet, and the diffusion path of heavy rare earth elements is designed and constructed to promote the diffusion efficiency and distribution uniformity of heavy rare earth Dy and Tb in the diffusion process. After previous research, the rapid diffusion of heavy rare earth elements has been achieved, the same performance time has been reduced by 65%, and the element distribution uniformity element is higher than that of the traditional diffusion magnet. The above technologies have passed the pilot test and have been applied on a small scale in some magnetic materials enterprises in Ganzhou.

2. Low temperature delayed sintering technology.

In cooperation with Ganzhou Dongjiao rare Earth Co., Ltd., Fulte Electronics Co., Ltd., jointly improve the pulverization and sintering process and optimize the atmosphere protection process, the ultra-fine grained magnet without heavy rare earth is prepared, and its coercivity is the same as that of the magnet containing Dy, which greatly saves the cost and improves the economic benefit.

3. Structure design and levitation force simulation of maglev track

The efficient and intelligent permanent magnet maglev rail transit system, "rainbow", is a new traffic mode, which means that it is a smart rainbow over the city. the successful development of rainbow rail is of great significance to expand the application field of magnetic materials. The arrangement of magnets with different types of structures is simulated by Maxwell finite element software, and the magnetic field changes of different magnet combinations are calculated. According to the theoretical calculation, the best arrangement of magnetic rails is obtained. In the case of the optimal magnet array, the maximum levitation force per unit volume is 92592.59 kN/m3, and the maximum levitation force can reach 12.5 kN. Through the measurement of the self-designed permanent magnetic levitation device, the measured results of the levitation force are basically consistent with the simulated values. the device is used to optimize the magnetic circuit design and arrangement, and greatly reduce the development cost of the maglev track.

4. Surface Protection of Magnet for Rail Transit.

Ni protective coatings with high density, low porosity and excellent surface quality were prepared on the surface of sintered Nd-Fe-B magnets by pulse thickening rapid deposition technology. the corrosion potential increased to-0.69V and the corrosion current density decreased to 1.875 × 10 ~ (- 6) A ~ (- 6) cm ~ 2, which greatly delayed the corrosion resistance rate of magnet grain boundaries. The Ni protective coating prepared by the new pulse rapid deposition technology has good compactness and strong adhesion to the magnet surface, which can effectively isolate and significantly improve the corrosion resistance of the magnet, improve the service performance of the magnet and prolong the service life of the maglev track.

Team building of the Institute

The institute is adhering to the concept of "school, army, family" trinity. In scientific research and learning, it is divided into several groups according to different research directions, and the group holds regular group meetings to discuss the work. The institute organizes a large group meeting every two weeks, each graduate student reports on his or her work every semester, and each teacher reports on the progress of cutting-edge scientific research. In addition, we invite many knowledgeable and experienced professors and researchers in the industry to communicate and discuss with us. The teachers of the institute also actively participate in industry meetings to exchange and discuss with their peers, and also provide opportunities for graduate students to go out for meetings and make conference reports, so as to increase their knowledge and broaden their horizons.

Apart from scientific research and study, the institute pays attention to the creation of a relaxed and pleasant living atmosphere, and has carried out many rich activities, such as annual summary meetings, collective mountain climbing, weekly basketball days, and so on. Through these activities, we can adjust the atmosphere and enhance our emotions. perfect expression of family-like care.
