In this study, a series of novel rare-earth co-doped zirconia powders and corresponding coatings with the nominal composition RE_0.02Gd_0.025Yb_0.025Y_0.05Zr_0.88O_1.94 (RE = Er, Eu, Sm, Nd) were successfully synthesized via solid-state reaction and deposited as coatings by air plasma spraying (APS). The phase structure and thermophysical properties were systematically characterized from room temperature to 1600 °C using X-ray diffraction (XRD) and laser flash analysis. All co-doped coatings exhibit a mixed monoclinic, tetragonal, and cubic phase structure. Notably, the ErZr coating shows similarly low thermal conductivity, with the lowest measured value of 2.24 W/(m·K) at 1600 °C. The calculated defect scattering coefficients (Γ ≈ 1.624-1.626) for the co-doped compositions are significantly higher than the coefficient of 8YSZ (Γ ≈ 1.054), confirming that multi-element doping introduces stronger phonon scattering through enhanced lattice distortion and oxygen vacancy effects.

Impedance spectroscopy measurements performed over the temperature range 300–480 K reveal a clear semiconducting behavior and conductivity saturation at high temperatures for all sintered samples. The electrical conductivity is strongly affected by the sintering temperature, reflecting the influence of microstructural evolution on charge transport. The conduction process is governed by thermally activated small-polaron hopping, with activation energies ranging from 0.482 to 0.577 eV. The investigated compound exhibits excellent thermistor performance, characterized by high material constants (β = 5430–6590 K) and large temperature coefficient of resistance. The temperature coefficient of resistance (TCR) analysis reveals the coexistence of both negative (NTC) and positive (PTC) thermistor behaviors depending on the operating temperature range.

A multiscale research framework combining molecular dynamics (MD), finite element method (FEM), scratching experiments, and turning experiments is established to investigate the material removal mechanism, brittle-ductile transition (BDT) behavior, and thermo-mechanical coupling in SiC machining. MD simulations reveal the atomic-scale evolution from plastic-dominated removal to brittle fracture with increasing scratching depth, while FEM simulations characterize stress concentration, crack initiation, and damage evolution at the continuum scale. Experimental results demonstrate that laser-induced thermal softening and surface oxidation, together with ultrasonic vibration-assisted intermittent cutting, effectively reduce machining resistance and suppress crack propagation. Compared with conventional machining, the laser-ultrasonic composite process decreases the scratching force by 71.0 % and the surface roughness by 60.9 %. Furthermore, the measured force reduction slightly exceeds the linear superposition of the reductions achieved by laser-assisted and ultrasonic-assisted machining alone, with a relative gain of 2.60 %, indicating a positive interaction trend.
