Abstract: (6301 Views)
The surface properties of metal-ceramic coatings based on titanium dioxide are described in dependence on the detonation spraying conditions. It is found that such properties as surface roughness, surface thickness and its hydrophobicity can be controlled in the production process by selecting certain values of the technological parameters of the spraying process. The optimal values of the technological parameters of detonation spraying, ensuring maximum hydrophobicity of the produced coatings are determined. The roughness of the coating surface and the coating thickness depend on the speed of the nozzle passage in accordance with the inverse power law. The roughness and the contact angle depend on spray distance in accordance with a parabolic law. New equations are obtained that can be useful for predicting the characteristics of the coating surface, as well as for determining the optimal mode of spraying the coating, ensuring its best hydrophobicity.
