“…Coefficient of friction of DLN films does not depend monotonically with chemical composition [24] . Lowest and highest reported coefficient of friction ranges were reported as 0.04-0.08 and 0.1-0.2 respectively.…”

“…It has been also reported [5] that wear resistance of DLN film is in the range of 0.2 -0.4 compared to wear factor of DLC film 0.5-1. Wear resistance is further decreased with increased concentration of Si and O [24] . In general DLN film has lower residual stress, lower coefficient of friction in dry as well as humid atmospheres.…”

“…The performance of DLN film from a tribological perspective was investigated by Venkatraman C et al [23] . The performance was satisfactory up to 400 0 C. Later, D. Neernick et al in one of their paper stated low-friction, low-wear combined with low internal stress and good adhesion of DLN coating make it suitable for tribological application [24] . Again D. Neernick et al reported low-friction and low-wear behavior of Diamond-Like Nanocomposite coatings even in humid environments.…”

This can be used as tribological coatings, chemical protective coatings [23][24][25]27,34] and abrasion resistant coatings. It has optical transparency over a wide bandwidth which includes visible light and infrared.…”

Diamond-like Nanocomposites (DLN) is a newly member in amorphous carbon (a:C) family. It consists of two or more interpenetrated atomic scale network structure. The amorphous silicon oxide (a:SiO) is incorporated within diamond-like carbon (DLC) matrix i.e. a:CH and both the network is interpenetrated by Si-C bond. Hence, the internal stress of deposited DLN film decreases remarkably compare to DLC. The diamond like properties has come due to

“…DLN film consists of diamondlike carbon bonds chemically stabilized by hydrogen atoms and quartz-like silicon bonds chemically stabilized by oxygen atoms in a pure amorphous structure. [8][9][10] This films can be deposited by different techniques like plasma enhanced chemical vapor deposition, [9][10][11][12] plasma assisted chemical vapor deposition, 13,14 thermally activated chemical vapor deposition 15 etc. To achieve better film properties, researchers need to investigate the details parameters like precursor flow rate, chamber pressure, substrate temperature, which are very important for good quality microstructure of the films.…”

Diamond-like nanocomposite (DLN) thin films were deposited on pyrex glass substrate using different flow rate of haxamethyldisiloxane (HMDSO) based liquid precursor with nitrogen gas as a glow discharged decomposition by plasma enhanced chemical vapor deposition (PECVD) technique. The significant influence of different precursor flow rates on refractive index and thickness of the DLN films was measured by using spectroscopic filmatrics and DEKTAK profilometer. Optical transparency of the DLN thin films was analyzed by UV-VIS-NIR spectrometer. FTIR spectroscopy, provides the information about shifted bonds like SiC2, Si-C, Si-O, C-C, Si-H, C-H, N-H, and O-H with different precursor flow rate. We have estimated the hardness of the DLN films from Raman spectroscopy using Gaussian deconvolution method and tried to investigate the correlation between hardness, refractive index and thickness of the films with different precursor flow rates. The composition and surface morphology of the DLN films were investigated by X-ray photo electron spectroscopy (XPS) and atomic force microscopy (AFM) respectively. We have analyzed the hardness by intensity ratio (ID/IG) of D and G peaks and correlates with hardness measurement by nanoindentation test where hardness increases from 27.8 μl/min to 80.6μl/min and then decreases with increase of flow rate from 80.6μl/min to 149.5μl/min. Finally, we correlates different parameters of structural, optical and tribological properties like film-thickness, refractive index, light transmission, hardness, surface roughness, modulus of elasticity, contact angle etc. with different precursor flow rates of DLN films
