The interface temperature reaches over 1000 ℃ in 1 s at an ultra-fast rate via the electric field assistance. The reaction layer of the joint consists mainly of Cr23C6 and the silicides of Fe, Co, Ni, and Cu. With the increase of brazing holding time, Cu gradually precipitates from the alloy, and the shear strength of the joints first increases and then decreases. The maximum strength value is 80 MPa at the test temperature of 800 ℃. This approach could help significantly improve the efficiency of ceramic bonding and achieve low-temperature joining for high-temperature applications. © 2024 Elsevier Ltd LA - English DB - MTMT ER - TY - JOUR AU - Lofaj, František AU - Kabátová, Margita AU - Kvetková, Lenka AU - Lisnichuk, Maksym AU - Albov, Dmitry AU - Jenei, Péter AU - Gubicza, Jenő TI - Structure, mechanical and tribological properties of Ta-xN coatings deposited by reactive HiTUS JF - JOURNAL OF THE EUROPEAN CERAMIC SOCIETY J2 - J EUR CERAM SOC VL - 44 PY - 2024 IS - 9 SP - 5326 EP - 5339 PG - 14 SN - 0955-2219 DO - 10.1016/j.jeurceramsoc.2023.11.020 UR - https://m2.mtmt.hu/api/publication/34376832 ID - 34376832 LA - English DB - MTMT ER - TY - JOUR AU - Wei, K.

In the present work, the influence of thermal processing parameters on the structure and electrical properties of NBT ceramics modified with 5 mol% sodium niobate (NBT-5NN) are evaluated. It is shown that quenching leads to higher electrical conductivity due to reduction at high temperatures, resulting in a higher oxygen vacancy concentration. The quenched materials also exhibit enhanced rhombohedral distortion and ferroelectric properties. The reduction process is largely reversible by reoxidation during annealing at intermediate temperatures in the region of 550 degrees C, which helps to recover the bulk resistivity to values close to those of the as-sintered materials. On the other hand, the rhombohedral distortion and ferroelectric properties were not affected significantly by the annealing procedure, indicating that the mechanisms responsible for the modification of electrical conductivity and structural distortion/ferroelectric properties have a different origin.
