Optical and tribological properties of decorative titanium carbonitride coatings

“…The C/N and Ti/CN signal ratios obtained by GD-OES analysis are shown in Figure 4. The C/N ratio increases with the increase of CH 4 addition in the gas mixture during the deposition process while the Ti/CN ratio decreases [1,18]. Therefore, one can conclude that the methane addition leads to increase the carbon content in the samples.…”

Unconventional Applications of Superconducting Nanowire Single Photon Detectors

“…The tradeoff for better sensitivity in infra-red is lower critical current density and , which translates into worse signal-to-noise ratio and need for better cryogenics. The main drawbacks of this family of materials is their sensitivity to chemical and physical conditions during thin film deposition, where substantial efforts have been made to achieve better consistency and process compatibility [ 78 , 79 , 80 ], and high reflectivity [ 81 , 82 , 83 ] that makes anti-reflective coatings or integration into photonic cavities necessary to achieve high quantum efficiency [ 4 , 84 ]. The second common class of SNSPD materials is that of amorphous superconductors, mostly popular for long wavelength photon detection.…”

Seramik Karoların Altın Dekorasyonunda Katodik Ark-FBB TiN Kaplama Proses Parametrelerinin Optimizasyonu

“…İdeal altın renklendirme stokiyometrik TiNx (x=1) bileşimi ile ifade edilirken, kompozisyonda N/Ti oranının artmasıyla (x1) bakır-kahve, N/Ti oranının azalmasıyla (x1) ise açık altın-gümüş renk oluşumu gerçekleşmektedir (Zeghni 2003, Lousa et al 2007. (Alves et al 2015, Niyomsoan et al 2002.…”

“…Özellikle katot akımı, reaktif gaz akış oranı ve kaplama süresi ile farklı kompozisyonda ve renklerde TiNx kaplamalar elde edilebilmektedir. İdeal altın renklendirme stokiyometrik TiNx (x=1) bileşimi ile ifade edilirken, kompozisyonda N/Ti oranının artmasıyla (x1) bakır-kahve, N/Ti oranının azalmasıyla (x1) ise açık altın-gümüş renk oluşumu gerçekleşmektedir (Zeghni 2003, Lousa et al 2007 (Alves et al 2015, Niyomsoan et al 2002. Bu bağlamda üretilen kaplamaların rengi N/Ti oranı ile ilişkilendirecek açıklanmıştır: K550-100, K650-100, K750-100 serisi kaplamalarda artan nitrojen ile kaplamaların rengi bakır-yeşil-mor olarak değişmiştir.…”
