In this study, a series of Hf-N films were fabricated by magnetron sputtering technology. The impacts of the Ar/N2 ratio on the micro-morphology and microstructure of the films were investigated, and the relationship between the film properties and its microstructure was further analyzed. It was observed that the surface morphology of the Hf-N films, which grew in a columnar crystal form, became denser with the elevation of the Ar/N2 ratio. When the Ar/N2 ratio was increased to 50:2.5, the composition of the film transformed into a single HfN phase, and this single-phase composition remained unaltered within a wide range of nitrogen flow. We discovered that the compressive stress and texture coefficient significantly contributed to enhancing the nanohardness of the films. Specifically, when the Ar/N2 ratio was 50:2.5, the film exhibited a maximum hardness value of 28.4 GPa along with an elastic recovery value of up to 63.1%.

However, a major challenge is how to efficiently manufacture multi-scale micro-nano structures to increase surface wetting gradients. In this study, a composite processing that combines nanosecond laser oblique incidence and thermal oxidation to fabricate microgroove-nanowire (CuO) hierarchical structures with gradient wettability is proposed. Laser oblique incidence scanning is employed to fabricate microgroove structures with gradient geometric dimensions and chemical composition on the Cu surface, which in turn induced gradient wetting properties and facilitated the directed movement of droplets. The effect of scanning times on gradient structure and its wetting properties is also discussed in detail. To further enhance the directional flow distance of droplets, dense CuO nanowires are grown on the surface of microgrooves through thermal oxidation treatment, forming a micro-nano dual scale structure. The growth mechanism of nanowires is revealed, and the effects of thermal oxidation temperature and duration on nanowire growth and gradient wetting properties are discussed in detail. The gradient in contact angles, in conjunction with the variation in energy barriers in different directions, leads to more pronounced anisotropic wetting.
