“…A colour-difference calculation was made to quantify the colour variation among samples [20,21]. The ΔE*, according to the CIE, represents the difference between two colours and can be estimated by 2 , where the indexes 1 and 2 denote two different colours. Figure 8 shows the ΔE* where the x axis represents the difference between two samples.…”

“…Thin films for decorative purposes can be deposited by many techniques such as plasma enhanced chemical vapour deposition and physical plasma deposition (PVD) [1,2]. Cathodic arc deposition (CAE-PVD) is appreciated due to its characteristics like high deposition rate, good adhesion, flexibility of deposition parameters, compatibility with many substrates and colour reproducibility [3][4][5].…”

Stainless steel and chromium-electroplated metal can change their metallic surface aspects into different colours by thin film deposition technologies. In this study, the colour change of titanium carbonitride (TiC x N y ) thin films as a function of N 2 and CH 4 flow rates in the deposition process was investigated. TiC x N y thin films were deposited by cathodic arc in an industrial equipment at low temperature (125°C) for decorative purposes. The samples were analysed by X-ray diffraction, scanning electron microscopy, glow discharge optical emissions spectroscopy, nanohardness, nanoscratch test and colorimetric analysis. The colour slightly changes from yellow gold to light bronze with carbon addition in the thin film structure. Scratch test determines an increase of the critical load for both plastic deformation and delamination as the carbon content increases. The failure mode shifts from brittle/ductile mode to ductile mode with the increase of the carbon content.

“…Titanium nitride films have been the most extensively studied films among transition metal nitrides due to their superior characteristics such as high hardness, good wear resistance and better mechanical and optical properties [1,2]. In addition, several Ti-based multicomponent coatings like TiAlN, TiCrN and TiZrN exhibit significantly improved properties compared to TiN coatings [3 -7].…”

“…Properties of nanocomposite transition metal nitrides can be controlled by the type and level of elemental dopant and fabrication procedure. Nanocrystalline transition metal nitrides, carbides and carbonitrides have been investigated for their interesting optical and decorative properties [21][22][23][24][25]. Correlations between chemical structure and optical properties [21,22,25], and structural morphology and optical behaviours of CrN, ZrN, TiN systems have been established [21].…”

Since solar thermal collectors are considered to be the most direct way of converting the solar energy into the usable form, in the last few years growing attention has been paid to the development of transition metal nitride and metal oxynitride based thin film selective surfaces for solar-thermal collectors in order to harvest more solar energy. A solar-thermal energy system, generally, shows very high solar absorption of incident solar radiation from the solar-thermal collectors in the visible range (0.3 to 2.5 µm) and extremely low thermal losses through emission (or high reflection) in the infrared region (≥ 2.5 µm). The efficiency of a solar-thermal energy conversion system can be improved by the use of solar selective surfaces consisting of novel metallic nanoparticles surrounded in metal nitride/oxynitrides systems. In order to enhance the effectiveness of solar thermal devices, solar selective surfaces with high thermal stability are a prerequisite. Over the years, substantial efforts have been made in the field of solar selective surfaces to attain higher solar absorptance and lower thermal emittance at high temperature (above 400°C) applications. In this article, we review the present state-of-the-art transition metal nitride and/or oxynitrides based vacuum sputtered Page 1 of 36 AUTHOR SUBMITTED MANUSCRIPT-JOPT-104532.R1 nanostructured thin film coatings with respect to their optical and solar selective surface applications. We have also summarized the solar selectivity data from recent published literature investigations, including discussion on some potential applications for these materials.
