And friction force (FF) images with the laser-patterned DLN film are shown in Figure ten. A region near the corner from the microcrater structure was examinedCoatings 2021, 11,12 ofto examine the friction forces around the original and laser-patterned DLN surface. Related for the preceding research [25], the LFM ARQ 531 Biological Activity imaging was carried out making use of worn Si guidelines with the tip radius of 0.five . The friction contrast is clearly noticed and characterized by significantly reduced friction forces inside the laser-patterned area than on the original surface, see Figure 10b. As a result of fairly deep craters, the contribution of your surface relief slope for the lateral force signal is just not fully compensated through subtraction of two lateral force photos [46], major to “higher friction” at the crater edges. The decrease friction forces inside the laser-patterned area are accompanied with a lot decrease pull-off forces (Fpull-off ) than on the original film, as confirmed by the force istance curves (Figure 11a) measured in distinct positions inside the FF image in Figure 10b, namely: (1) Fpull-off = 1290 nN on the original film, (two) Fpull-off = 990 nN near the area of redeposited material, (3) Fpull-off = 63 nN inside the area of redeposited material, and (four) Fpull-off = 16 nN in the center of a crater. This suggests that the ablated and redeposited material modifications the nanoscale surface properties inside and around the laser-produced microcraters. The region from the low-friction area 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 reduced friction and pull-off force (than on original Coatings 2021, 11, FOR PEER Overview 13 of 16 Coatings 2021, 11, xxFOR PEER Review 13 of to surface) is almost certainly triggered by mass distribution of ablated clusters/particles, leading 16 variation within the structure and/or thickness in the redeposited layer.Figure 10.
