Laser Textured Surfaces for Mixed Lubrication: Influence of Aspect Ratio, Textured Area and Dimple Arrangement
Unidirectional sliding experiments with polished and laser textured steel surfaces were carried out to investigate the effects of different textured area densities, aspect ratios and dimple arrangements. The system was lubricated with Polyalphaolefin (PAO) at 100 °C and the contact pressure was 3 MPa. For measuring Stribeck curves, the sliding speed was controlled between 40 and 2000 mm/s. The ...
متن کاملNumerical investigation of the tribological performance of micro-dimple textured surfaces under hydrodynamic lubrication
Surface texturing is an important approach for controlling the tribological behavior of friction pairs used in mechanical and biological engineering. In this study, by utilizing the method of three-dimensional computational fluid dynamics (CFD) simulation, the lubrication model of a friction pair with micro-dimple array was established based on the Navier-Stokes equations. The typical pressure ...
متن کاملWetting of textured surfaces
We discuss quantitatively the wetting of a solid textured by a designed roughness. Both the hydrophilic and the hydrophobic case are described, together with possible implications for the wetting of porous materials. © 2002 Elsevier Science B.V. All rights reserved.

متن کاملComputer Description of Textured Surfaces
This work deals with computer analysis of tex tured surfaces. Descriptions of textures are form alized from natural language descriptions. Local texture descriptions are obtained from the direction al and non-directional components of the Fourier transform power spectrum. Analytic expressions are de rived for orientation, contrast, size, spacing, and in periodic cases, the locations of text...
متن کاملHydrodynamic lubrication of textured surfaces: A review of modelling techniques and key findings
Understanding the influence of surface properties (roughness, grooves, discrete textures/dimples) on the performance of hydrodynamically lubricated contacts has been the aim of numerous studies. A variety of different numerical models have been employed by many researchers in order to find optimal texturing parameters (shape, size, distribution) for best performance enhancement in terms of load...
