In this study, inspired by the wrinkle morphology of the Camponotus ant with thermoregulation, a biomimetic amorphous coating composed of a hemispherical array was fabricated on aluminum alloy using plasma electrolytic oxidation (PEO) technology. This biomimetic microstructure is obtained by controlling the content of hexagonal boron nitride (h-BN) nanoparticles in the electrolyte, where the increase in current density at a later stage allows the transition of the porous coating to the hemispherical array. The effects of functional group vibration and rotation in combination with the hemispherical structure afford the biomimetic coating a high emissivity of 0.91 within the range of 3–14 μm, which reduces the LED temperature by 17.1 °C and achieves a cooling efficiency of 10.6 %. Meanwhile, with a resistivity of 5.15 × 1014 Ω∙cm and a dielectric strength of 29.9 V/μm, the coating can prevent current leakage, consequently improving the stability and reliability of electronic packaging materials. In addition, h-BN flakes in the biomimetic coating with almost defects free act as a protective barrier to enhance the corrosion resistance of the aluminum alloy.

A ball-on disk tribometer assessed coating wear and friction behavior at room temperature (RT), 300, and 600 °C with loads of 10 and 20 N. The wear rate and mechanism were assessed using SEM-EDX and an optical profilometer. The coating characteristics included density, porosity, surface roughness, microstructure, and microhardness. The bond strength of Amdry1371 and Amdry1371/30%WC-Co coatings is analyzed using the scratch test. During the scratch test, both coatings show cohesive failure at 30-50 N and cohesive along with adhesive failure at 70 N loads. Compared to Amdry1371 coating, Amdry1371/30%WC-Co coating has greater microhardness and bond strength. The wear rate and friction coefficients of Amdry1371 and Amdry1371/30%WC-Co coatings increase with temperatures up to 300 °C and decrease at 600 °C. Wear debris is generated when contact surfaces fracture under the applied load, acting as a third body in the sliding process.

This glaze layer is present on worn surfaces, significantly reducing friction coefficients and the wear rate of coatings.

The results show that in three different electrolytes, the loads exhibited second-order LCR oscillation attenuation characteristics. Before the electric spark breakdown more ions would gather at both ends of coating No. 2 because of the largest capacitance C.

During the coating growth the ion migration speed and heat output were closely related to Ra because the values of Ra were markedly greater than that of R0.

Herein, we report the deposition of MPEN sputtering coatings of the Ti-Al-Zr-Mo-N system following the microstructure and morphology behavior as a function of the variation of Mo from 0 to 31.5 at.%. The phase evolution evidences significant changes from a predominant B1 (NaCl-type) structure with disordered N vacancies for the lower Mo contents to a predominant β (tetragonal) phase with ordered N vacancies for the higher Mo contents, which leads to remarkable morphological changes in the coatings. In addition, we found the best tribomechanical performance in the coating with a mixture between B1 (disordered N vacancies) and β (ordered N vacancies), due to a synergistic effect based on the resultant texture in each phase. Furthermore, the best protective character against corrosion was found to have a decreasing trend as the Mo content increased. These results demonstrate the need for optimization strategies to determine the balance between opposing effects of phenomena that occur during the deposition of MPENs, mainly those driven by the nature of the metal constituents and their atomic ratio.
