The evolution of interface characteristics and heat transfer mechanism of joint were studied in detail. The results showed that the diamond interfacial thermal conductivity is greatly enhanced by the continuous nano TiC interlayer. Meanwhile, by adjusting the brazing temperature to eliminate the seam defects and obtain the appropriate width of seam and diffusion zone, it is also helpful to improve the joint performance. The high temperature performance of joint was also characterized, the thermal conductivity and shear strength of joint remained at 499 W/m∙K and 160 MPa respectively at 400 °C.

SEM and wear studies revealed that the AXL coating, characterized by its dense microstructure and minimal porosity, exhibited superior hardness (12.1 GPa) and least specific wear rate (0.1 × 10⁻⁶ mm³/N-m). In contrast, 9MB and SLX coatings showed relatively higher porosity, lower hardness, and increased wear rate.

The experimental rheological data measured with a high-temperature rheometer up to 1550 °C were supported by the study of the internal structure by an X-ray powder diffraction analysis (XRPD), scanning electron microscopy with an energy-dispersive X-ray spectroscopy (SEM/EDX), a Fourier transform infrared spectroscopy (FTIR) and Raman microspectroscopy. The increase in the B₂O₃ content in the samples caused a dramatic decrease in the softening and liquidus temperatures. Up to 15 wt% B₂O₃ content, it was possible to determine the break temperature, which decreased with increasing B₂O₃ content. The exponential decrease in dynamic viscosity with an increasing temperature and its decrease with an increasing B₂O₃ content was caused by the decrease in the [BO₄] tetrahedra coupled with an increase in the [BO₃] units and boroxol rings, leading to a simplified structure with a higher number of non-bridging oxygens. Semiempirical models (Arrhenius, VFT, Riboud, Urbain, and Ray and Pal) were used to compare experimentally acquired dependencies with theoretically obtained ones. The dependence of dynamic viscosity over the temperature range of 1320–1520 °C and a B₂O₃ content 0–30 wt% was predicted with a relative error of 2.5 % using an artificial neural network (ANN).

In this study, the effects of trace BNT doping on the crystalline structure, microstructure and PTCR properties of La, Nb and Mn Co-doped BaTiO₃ PTCR ceramics were investigated. The results show that with the increase of BNT content, the lattice parameters, tetragonality and grain size decrease, while the Curie temperature increases monotonously. However, the room temperature resistivity decreases at first and then turn over to increase as the BNT content increases, reaching its minimum value at the sample doped with 0.25 mol % BNT.

Bi³⁺ ions enriched in the grain interior affect the resistivity as donors, while Na⁺ ions enriched in the grain boundary affect the grain boundary barrier as acceptors.
