Spark plasma sintering and a standard sintering method are used to manufacture ceramic plates with a diameter of 30 mm from aluminum oxide powder with a fraction size approximately equal to 3 µm. Dynamic strength of the ceramics obtained is studied. Dynamic loading is carried out by a hardened steel impactor. It is shown that energy dissipation in a material obtained using spark plasma sintering is substantially larger than that in a material produced using standard sintering, which means that it is more resistant to dynamic loads.

火花等离子烧结氧化铝基细粒陶瓷动态强度的实验研究

放电等离子烧结和标准烧结方法用于从氧化铝粉末制造直径为 30 毫米的陶瓷板，氧化铝粉末的粒度大约等于 3 微米。研究所得陶瓷的动态强度。动态加载由硬化钢冲击器执行。结果表明，使用放电等离子烧结获得的材料的能量耗散明显大于使用标准烧结生产的材料的能量耗散，这意味着它更能抵抗动态载荷。
