Tribological properties of diamond-like nanocomposite coatings at high temperatures

Solid state magnetic resonance investigation of the thermally-induced structural evolution of silicon oxide-doped hydrogenated amorphous carbon

“…Silicon oxide-doped hydrogenated amorphous carbon (a-C:H:Si:O) coatings were deposited on aluminum foils by Sulzer-Metco Inc. (Amherst, NY, USA) using a proprietary plasma-enhanced chemical vapor deposition (PECVD) process, whose details are described elsewhere [49][50][51][52][53][54][55][56][57].…”

Frequency response of Diamond-like Nanocomposite thin film based MIM capacitor and equivalent circuit modelling

“…Apart from this when thickness of DLN film increases the field strength decreases for specific potential difference and the path length for electrons also increase as a result time for transportation further increase causing lowering of EPC. When the frequency is quite high >10 4 Hz the decrement in EPC reduces causing more or less a steady capacitance for thicker film (Fig. 9).…”

“…These are one diamond like carbon bonds network stabilized by hydrogen (a-C:H) and another quartz like silicon network stabilized by oxygen (a-Si:O) [1][2][3][4].Different chemical bonds between constituent atoms of the two networks lead to low residual stress [8]. Apart from different tribological [3,4,6], thermal [4,5], chemical [10], biocompatibility [7] properties, DLN has also good dielectric properties [1,2]. DLN possess electrical resistivity of 10 8 to 10 14 ohm cm, dielectric constant 3 to 10 and breakdown strength in the range of 10 6 to 10 8 V/cm [1,2,9].…”

Characterization and Applications of Diamond-like Nanocomposites: A Brief Review

“…DLN coating have excellent bulk and surface property as well as thermal stability. 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.…”

“…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] .…”
