And friction force (FF) photos of the laser-patterned DLN film are shown in Figure 10. A area near the corner on the microcrater structure was examinedCGS 21680 web Coatings 2021, 11,12 ofto evaluate the friction forces on the original and laser-patterned DLN surface. Related for the earlier research [25], the LFM imaging was carried out applying worn Si strategies using the tip radius of 0.five . The friction contrast is clearly seen and characterized by considerably lower friction forces within the laser-patterned area than around the original surface, see Figure 10b. Because of fairly deep craters, the contribution in the Elesclomol References surface relief slope towards the lateral force signal just isn’t fully compensated throughout subtraction of two lateral force photos [46], leading to “higher friction” at the crater edges. The reduce friction forces in the laser-patterned area are accompanied with a great deal decrease pull-off forces (Fpull-off ) than around the original film, as confirmed by the force istance curves (Figure 11a) measured in different positions inside the FF image in Figure 10b, namely: (1) Fpull-off = 1290 nN around the original film, (two) Fpull-off = 990 nN near the area of redeposited material, (three) Fpull-off = 63 nN inside the area of redeposited material, and (4) Fpull-off = 16 nN inside the center of a crater. This indicates that the ablated and redeposited material adjustments the nanoscale surface properties within and around the laser-produced microcraters. The location of your low-friction region with redeposited material covers the distance of 102 in the crater edge and, like the crater, it covers a circle area of 157 radius. The occurrence in the area “2” with slightly lower friction and pull-off force (than on original Coatings 2021, 11, FOR PEER Overview 13 of 16 Coatings 2021, 11, xxFOR PEER Assessment 13 of to surface) is probably brought on by mass distribution of ablated clusters/particles, top 16 variation inside the structure and/or thickness on the redeposited layer.Figure ten.
