The main obstacle to calculate the 'feel' of a product from its surface properties is the ill-defined surface topography that is encountered after the most surface finishing processes. In this work this obstacle was avoided by producing well-defined surface topographies by laser texturing. The friction of textures having surface features with...

By laser ablation with ultra short laser pulses in the pico- and femto-second range, well controlled dual scaled micro- and nano-scaled surface textures can be obtained. The micro-scale of the texture is mainly determined by the dimensions of the laser spot, whereas the superimposed nano-structure is the result of so-called laser induced "self...

Laser induced self-organizing rippled nanostructures on steel are formed by femtosecond laser pulses. They are applied as hydrophobic surfaces. A low fluence results in ‘regular ripples’ with a spatial repetition of 300–500 nm, orientated perpendicular to the laser polarization direction. In twinned areas ‘pre-ripples’ with much smaller...

The origin and growth of a self organizing rippled nanostructure have been studied on slightly etched high temperature steel using 240 fs laser pulses with a wavelength of 800 nm. SEM, AFM and confocal microscopy have been used for analyses. A relatively low energy input results in a regular structure with a wavelength in the range 300 - 500 nm...
