A novel method for preparing aluminum/aluminum nitride ceramics (Al/AlN) substrates is proposed in this paper. The method included two processes: (1) the surface of AlN was coated with a CuO thick film and sintered; (2) Al foil was put on the pretreated (in process 1) AlN surface and bonded to AlN through pre-heating at 400°C and final heating at 660°C in N2-H2 reduction atmosphere. The experimental...
In this work, the adhesion energy, interfacial energy, interface bonding and interface magnetism of LaAlO3/Ni interface were calculated by the first-principles method. Meanwhile, the effectiveness of LaAlO3 as the heterogeneous nucleus of Ni grains was also analyzed. The results show that the Wad of the AlO2-O-OT interface is the largest, which is 3.58J/m2. Those of the LaO-OT interface and AlO2-Al-OT...
