“…Visual examination, however, showed a dark-gray to black color. Apparently, the light falling on the roughened surface gets scattered and absorbed, resulting in the appearance of dark surfaces [16,17]. For this reason, optical microscopy of the surfaces was difficult.…”

“…MCA is produced by laser ablation with an excimer laser having energy in the range of a few Joules, pulse duration of 0.002-1.5 ms, and wavelength in the range of 1.15-11.00 mm. Such adjustable characteristics of the laser allow variation of the material choice and MCA process parameters over a wide range [16,17]. An example of MCA formed on the surface of steel is shown in Fig.…”

“…Laser-assisted surface structuring approach has shown great potential for production of highperformance metal thermal emitters [21][22][23][24], addressing some intrinsic shortcoming of other fabrication techniques such as materials selection, area limitation and cost. A large variety of surface topographies can be accessed by varying laser treatment parameters (i.e.…”

Effective thermal management is of paramount importance for all high-temperature systems operating under vacuum. Cooling of such systems relies mainly on radiative heat transfer requiring high spectral emissivity of surfaces, which is strongly affected by the surface condition. Pulsed laser structuring of stainless steel in air resulted in the spectral hemispherical emissivity values exceeding 0.95 in the 2.5–15 µm spectral region. The effects of surface oxidation and topography on spectral emissivity as well as high temperature stability of the surface structures were examined. High performance stability of the laser textured surfaces was confirmed after thermal aging studies at 320°C for 96 hours.

“…Previous work has identified that microcolumnar array (MCA) structures, produced by laser surface modification, could enhance the adhesive bonding strength for metals, alloys and ceramics [8][9][10]. The idea that adhesion depends on the mechanical interlocking of the adhesive with surface roughness is frequently discussed in the literature and is believed on a wide scale.…”

a b s t r a c tGlass is a promising substitute substrate material being evaluated for electronic packaging technology. Improving the electroless copper plated layer adhesion of the glass is one of the most important considerations for development of the technology. An excimer laser (248 nm) was used for structured texturing of glass surfaces (to improve adhesion) by changing mask dimensions, laser operating parameters and overlapping pitch spacing, and therefore producing a range of micro-scale features. Electroless plated copper adhesion strength was assessed using quantitative scratch testing, demonstrating that micro-patterned structures can significantly improve copper/glass adhesion. New ISO 25178 Part 2 areal surface texture parameters were used to characterise the surface roughness of ablated glass surfaces, and correlated to the scratch testing results. Highly correlated parameters were identified that could be used as predictive surface design tools, directly linking surface topography to adhesion performance, without the need for destructive adhesion quantification via scratch testing.
