“…1 DLC films have been utilized industrially as a wear resistant coating for hard-disk drive, optical component and also in the form of biocompatible coatings for medical purpose because of their excellent properties like high hardness, low coefficient of friction (COF), high wear resistance, chemical inertness, good optical transparency etc. [2][3][4][5][6][7] But DLC films can't retain their all characteristics at higher temperature because of conversion of sp 3 hybridized carbon to sp 2 hybridized carbon. Although, DLC films have high intrinsic compressive stress between the films and substrate, which generally provide the poor adhesion between film and substrate.…”

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

“…The problems include damaged base material due to the heat during deposition, residual stress between coating and base material, and a lack of adhesion. On the other hand, hydrogenated amorphous carbon (a-C:H) usually has rather low hardness and friction coefficient [1], and so, coating with a-C:H is useful for soft materials like rubber and plastic that is why its application for industrial products has been advanced [2,3]. In order to expand its application, it is essential to develop a coating process.…”

Hydrogenated amorphous carbon (a-C:H) films were deposited on rubber surface by plasma-enhanced chemical vapor deposition (CVD), using a non-equilibrium atmospheric pressure plasma torch. The effects of oxygen, in the deposition atmosphere, on the chemical and mechanical characteristics of a-C:H films were investigated. It was clarified that the amount of carbon atoms combined with oxygen atoms in the a-C:H films increased with the increase of the oxygen content in the deposition atmosphere. On the other hand, surface hardness decreased as the oxygen content increased. As a result, a very low frictional property of a-C:H films was achieved by CVD, using the non-equilibrium atmospheric pressure plasma torch with eliminating oxygen from the deposition atmosphere.

“…Nowadays carbon-based coatings attract interest for applications as protective coatings in many areas, such as magnetic storage disks, sliding bearings, gears, manufacturing tools, polyethylene terephthalate (PET) bottles, in textile and biomedical industries [13][14][15] . They can present low coefficient of friction 13 and reduced wear rate, being good candidates for tribological applications.…”

Ti-doped carbon coatings were deposited on TiAlV alloys by reactive dc-magnetron sputtering in Ar/CH 4 mixed gas. When Ar flow increases the incorporation of Ti into films raises while the concentration of C decreases. The formed nanometric TiC crystals were more noticeable for coatings deposited with higher Ar flows. Hardness (H) and elastic modulus (E) of coatings were measured by nanoindentation. H values were in the range of 8.8-15.9 GPa and E of 53.4-113.7 GPa. Higher values for H and E were obtained for films containing larger amount of TiC-phase. The presence of TiC crystals increased the coefficient of friction (COF) from 0.07 to 0.28 in scratch tests. Tribological experiments were carried out by using a pin-on-disk apparatus in air and in liquid. COF values ranged from 0.10 to 0.50 for tests in air. Despite of presenting higher COF, tests performed in liquid resulted in less pronounced wear tracks.
