Manufacturing textured surfaces: State of art and recent developments (2015, background): “Equally, the size of the thermal affected zone surrounding a 10-mm diameter hole induced using Nd: YAG laser pulses can be smaller than 10% of the texture diameter.(92) Surface defects such as bulges or burrs represent another issue when using LST technology.”
Optimization of the surface texture for silicon carbide sliding in water (2006, background): “The surface texture, such as artificial micro-grooves or micro-dimples fabricated on the contact surfaces has proven to be effective to improve the tribological performances of sliding [1–6].”
Friction characteristics of microtextured surfaces under mixed and hydrodynamic lubrication (2013, methodology): “An important characteristic of these textures is the absence of material pile-up around the circumference of the dimples that are typical of laser surface texturing methods [19,29].”
