Hydrophobic and highly hydrophobic zirconia coatings are obtained by air-plasma spraying of powder and suspension materials. The proposed method and the developed equipment make it possible to obtain nanostructured surfaces with water-repellent properties. The high hydrophobicity of the coating is achieved by creating a hierarchical texture of its surface obtained by the combined method of plasma spraying of powder and liquid-phase materials. The developed surface of the coating based on zirconia ZrO₂ obtained by the method of sequential plasma spraying of micropowders (with 20–40 µm microparticle sizes) and liquid materials in the form of suspensions (with 50–100 nm nanoparticle sizes) makes it possible to increase the water-wetting angle up to 145 degrees.

疏水性和高度疏水性的氧化锆涂层是通过对粉末和悬浮材料进行空气等离子喷涂获得的。所提出的方法和开发的设备使得获得具有疏水性质的纳米结构表面成为可能。涂料的高疏水性是通过使粉末和液相材料通过等离子喷涂的组合方法在其表面形成层次结构来实现的。通过依次等离子喷涂微粉（粒径为20–40 µm）和悬浮液形式的液体材料（粒径为50–100 nm）获得的基于氧化锆ZrO ₂的涂层的已开发表面成为可能将水润湿角增加到145度。
