Rectangular spot size (mm2): 10 × 2 Authors found that HEA coating exhibited high wear resistance at the 2.6 kW and 4 mm/s. Wear protection of cutting tools Guo et al. [89] AlCrFeCoNi onto 1100 Aluminum substrate using Nd: YAG laser Pulse Power (kW): 1 and 1.2Scan ...
The porosity study revealed the pores population in the [30;121] p/mm2 range, with a median circularity C50p = [0.30;0.55] and a median pore size DE50p = [65;100] μm. No clear trends can be observed with any of the porosity metrics in respect to the process parameters. Concerning...

When the biofilms on the carriers from sites 26 mb, 26 db, and 36 mb were analysed, in terms of the number of cells of six distinct morphotypes present on the 6 mm2 surface area [Figure 4], it was obvious that the colonisation was very luxuriant and that the three sulci differed very...

The beam dimensions and the beam divergence are 14 × 7.5 mm2 and 2 × 1 mrad,2 respectively. At the distance of 90 mm from the sample, the laser irradiated vertically onto the sample surface through a 4 mm × 7.5 mm diaphragm. The pulse energy Ein on sample was varied between 13 ...
Actually, the whole voltage is n times higher than that of the S-PVLPC minus n(kT/q)ln(n), n being the number of subcells and the rest of the symbols with their usual meaning), whereas the current of the whole device is the same as that of a subcell (n times lower than that...
Finally, the value of Ma increased. When the laser energy density reached 90 J/mm2, there were obvious signs of Marangoni convection in the coating, as shown in Fig. 3(d,e). And the width and dilution ratio of the coating increased as Marangoni convection becomes stronger. Download: ...
LIBS involves focusing a pulsed laser beam with an irradiance of at least 10 MW/mm2 onto a solid, liquid, or gaseous target. The intense photon flux breaks down the target material resulting in a plasma. The excited electronic states in the plasma emit light at characteristic wavelengths, ...
Furthermore, four rectangular grooves with an area of 1.8 × 7 mm2 and depth of 0.05 mm were carved on each QTF prong surface in order to provide a reduced electrical resistance R without affecting the quality factor Q. Such a modified QTF has a R value of 107.15 kΩ ...
