Ysed within this work had common thicknesses of quite a few millimetres, it might be affordable to consider coatings that exhibit a life time that exceeds these of PVD coatings by a factor of 10.000. Needless to say, the question remains regardless of whether applications exist that would make it achievable to benefit from these tremendous life occasions. five. Conclusions Additive manufacturing of Reldesemtiv Autophagy tungsten carbide surfaces can cause wear-resistive surfaces that will very easily be manufactured in almost arbitrary geometries and exhibit a good adhesion to stainless steel substrates. Tribological tests revealed very constant coeffi-Coatings 2021, 11,9 ofcients of friction which can be highly fascinating for technical applications. Each the adhesion of your cobalt-containing tungsten carbide phase on steel bodies along with the formation of homogeneous microstructures do not pose dramatic problems. A final mechanical surface treatment procedure following deposition led to wear-resistive WC/Co surfaces that exhibited exceptionally low put on prices below dry conditions. The so-prepared surfaces exceeded the life time of high-quality PVD-coated surfaces by orders of magnitude.Author Contributions: Conceptualization, J.A. and M.M.; methodology, J.A. and M.M.; validation, F.K., M.S., J.A. and M.M.; investigation, F.K. and M.S.; information curation, F.K. and M.S.; writing–original draft preparation, F.K. and M.S.; writing–review and editing, J.A. and M.M.; visualization, F.K. and M.S.

coatingsArticleDefective Microwave Photonic Crystals for Salinity DetectionYuxia Zhu 1,2, and Hongwei Yang1College of Food Science and Technologies, Nanjing Agricultural University, Nanjing 210095, China Department of Physics, Nanjing Agricultural University, Nanjing 210095, China; [email protected] Correspondence: [email protected]: In this paper, defective microwave photonic crystals (MPCs) are made to sense the salinity of aqueous options. The defective MPC sensors are constructed by two kinds of microwave dielectric layers and a single defective salt option layer. Transfer matrix technique (TMM) for lossy medium is created to calculate the transmittance spectra of the sensors. It is actually located that the peak transmittance of both the defective resonance within the microwave band gap (MBG) and transmitting modes outside the MBG monotonously decrease using the improve of salinity, when the resonant and transmitting mode frequencies remain unchanged. By comparing the 4 MPC sensor structures, the initial transmitting mode inside the upper frequency band outdoors the MBG of the 15-layer MPC sensor has the largest salinity sensing variety from 0 to 40 with relative steady detecting sensitivity. The sensing principle is primarily based on the fact that the dielectric loss element of saline option is much more sensitive to salinity than the dielectric continuous inside the microwave frequency band. The sensitivity, high-quality element, and salinity detection range in the MPC sensors are calculated and compared.
