We propose a new laser-based fabrication process of small-sized riblets on PWA1483 coated on a 3 μm-thin sputtered Ni/Cr/Ni multilayer. Laser ablation was used for local material removal. Subsequent oxidation was used to provide an optimal riblet dimensions for a drug reduction and oxidation resistance. As a result of the heat treatment, a 7 μm oxide film was formed. The oxide film consists of two different oxide layers: while the upper one is formed of a dense Cr₂O₃ layer with NiO, Cr₂NiO₄, and TiO₂ inclusions, the bottom one mainly consists of alpha-Al₂O₃. Between the riblets, a TiO₂ layer was formed on the top of Cr₂O₃ layer. First mechanical tests showed a promising riblet stability under the low-cycle fatigue load, under tension, and under quasi-cyclic bending load. The riblets also exhibit no severe failure by applying a quasi-cyclic bending stress of 900 MPa for 200 times. Furthermore, cyclic tensile loading with a mean load of 500 MPa and an amplitude of 220 MPa corresponding to a strain range of 0.35% (stress level of R = 0.35) led to no damage of the riblet structure.
