This study explores the performance of micro-textured tools when cutting GH4169 during spray cooling. First, morphologies micro-textures were selected according to simulation and experiments. Secondly, experiments carried out As appropriate for each experiment, regression models force, temperature, or tool wear area established, variance analysis was conducted. The functions obtained from respe...

Abstract An experimental investigation was performed for investigating the tribological performance of micro-dimple surface texture patterns on a cylindrical in realistic operating environment starved lubrication. Micro-dimples were generated by dual-frequency texturing method, which high-frequency (16.3 kHz) three-dimensional (3D) vibration and low-frequency (230 Hz) one-dimensional (1D) appli...

Hierarchical textures (combining 2D periodic large and small micro textures) as an external outcoupling solution for OLEDs have been researched, both experimentally by optical simulations. For the case of a red bottom emitting OLED, different hierarchical were fabricated using laser-based methods replication step applied to OLED substrate, resulting in increased light outcoupling. Laboratory-si...

Improving the magnetic properties of non-oriented electrical steel (NOES) through optimization crystallographic texture has been an on-going research activity for decades. However, using traditional rolling and annealing procedures, obtained final textures were usually very similar, i.e., exhibiting {111} (γ) <110> (α) fibres, which not desired {001} (θ-fibre) optimal quality. In current work, ...

Polydimethylsiloxane (PDMS Sylgard 184, Dow Corning Corporation) pre-polymer was combined with increasing amounts of cross-linker (5.7, 10.0, 14.3, 21.4, and 42.9 wt.%) and designated PDMS1, PDMS2, PDMS3, PDMS4, and PDMS5, respectively. These materials were processed by spin coating and subjected to common micro-fabrication, micro-machining, and biomedical processes: chemical immersion, oxygen ...

Procedural textures have significant advantages over image textures. Procedural textures are compact, are resolution and size independent, often remove the need for a texture parameterization, can easily be parameterized and edited, and allow high quality antialiasing. However, creating procedural textures is more difficult than creating image textures. Creating procedural textures typically in...
