A Fe-22Cr mesh/LaNi0.6Fe0.4O3-δ (LNF) composite, obtained via dip coating technique, was machined using a femtosecond laser as a possible gas permeable contact layer for solid oxide fuel cells (SOFCs). Both electrical performance and processing reproducibility of {Crofer22APU channeled interconnect-ablated composite contact material-La0.6Sr0.4FeO3 (LSF) cathode} structure were studied through electrochemical measurements on four replicas. For comparison, the obtained area specific resistance (ASR) data, under similar measurement conditions, for {flat Crofer22APU/LNF contact perovskite/LSF} and {channeled Crofer22APU/contact composite} setups are also presented. The results support the reproducibility for the measured ablated final systems, obtaining average ASR value of 0.06(1) Ω cm2 at 800 ºC, in air.

“…Moreover, machining of yttria tetragonal zirconia polycrystalline ceramic with an ablation rate of up to 1.35 mm min −3 and a surface roughness of R a =2.8 µm was shown [17]. In comparison to metals, the ablation characteristics of ceramics show a pronounced depen-55 dence in terms of heat-affected zone on the number of applied laser pulses per area [18]. The reported studies on orthogonal laser machining point directly to the problem in terms of surface quality and geometrical precision.…”

A novel approach for machining of cylindrical hard materials and arbitrary shapes is presented. Alumina-toughened zirconia dental implants with complex geometry are manufactured with femtosecond quasi-tangential laser ablation. This rapid-prototyping approach for small-scale production decreases the development-time cycle tremendously and trumps conventional approaches. Moreover, a competitive parameter study for radial and tangential ablation with single and multi-pulse is presented. A process achieving an ablation rate of 1mm3/min with a surface roughness Ra of 0.2 µm is introduced. The meta-stable tetragonal phase of the ceramic persists and is assessed via Raman spectroscopy. The small heat-affected zone is subsequently ablated with a radial laser process step. Hence, high-precision dental implants with a mean error of smaller 5 µm over the complete contour are shown.

“…In the literature, investigations of laser ablation are often performed on pure metals for which physical properties are well known (Nolte et al, ; Mannion et al, ; Colombier et al, ). Results on other types of materials have also been reported, depending on application fields such as semi‐conductors for microelectronic, dielectrics for optical systems, polymers or corneal tissues for medical issues (Kruger, ; Ashkenasi et al, ; Rosenfeld et al, ; Di Maio et al, ). Finally unusual materials but specific to some applications require adapted characterizations.…”

We have investigated femtosecond (fs) laser (130 fs, 800 nm, 5 kHz) ablation of polypropylene (PP). The following laser process conditions were varied: power density and number of pulses. The morphological parameters' response (depth, ablation diameter, ablation volume) to the laser process conditions, measured by an optical profiler, was investigated by the statistical analysis technique to determine the relationship between them. For this, the simple linear regression and the multiple linear regressions are compared. The simple linear regression shows that the ablation volume follows a linear relationship with the product of the power and the number of pulse.
