MECHANICAL STRENGTH ANALYSIS OF PERMANENT MAGNET COMPONENTS
As for the mechanical strength of permanent magnet components,the researchers used the pressure testing machine to test the load limit of the products and observed the samples of the fracture surface with the scanning electron microscope. Then the researchers conducted comparative experiments on the permanent magnet components in the process of the pre-sintering,fine grinding and sintering,etc. The results show that Zr O2 should be added at 0. 10% 0. 20% with oxygen content at 9% 10% and pre-sintering temperature at 1 290 ℃ 1 310 ℃ for 2-hour preservation. Besides,the particle size of the slurry should be well distributed at the fine-grinding stage. In particular,the temperatures of permanent magnet components should increase slowly within the most-shrinkage temperature range（ i. e. 1 050 1 200 ℃） and be stably and effectively controlled at the highest sintering temperature area. All these requirements are conducive to the improvement of permanent magnet components in the respect of their microscopic structures,magnetic properties and load limit.
