WebFeb 3, 2024 · In this work, suspension plasma spraying (SPS) with different hydrogen (H2) flow rates was employed to produce TiO2 coatings with various phase contents, oxygen contents, and roughnesses. To eliminate the role of the morphology and oxygen content on the photocatalytic activity, all coatings were polished to reach the same roughness … WebSurface roughness is found to affect the substrate static and dynamic wettability for root-mean-square roughnesses below 7 nm. The kinetics of liquid–liquid displacement is slowed down drastically by the nanoroughness. Nevertheless, contact line motion is found to be governed by a thermally activated process.

WebIn pneumatic systems, unsuitable surface roughnesses that may occur (especially at the bottom of the groove) may cause leakage. After machining, honing, grinding and similar processes, compliance with the recommended. surface roughness values in all product channels as well as dynamic work surfaces has an important effect. WebOn the basis of stochastic theory two different forms of Reynolds-type equation corresponding to two different types of surface roughnesses are developed. It is shown that the mathematical form of these equations is similar but not identical to the form of the Reynolds equation governing the behaviour of smooth, deterministic bearing surfaces.

WebNikuradse (1933) provided relations between this shift Δu + and the reduced roughness height h s + = h s u τ /v for the specific sand-grain roughnesses of various heights h s he investigated. Note that for most types of “real-life” roughness, the sand-grain size h s that has the same effect is several times larger than the depth of the grooves or other …
