An examination of trace surface on diamond-like carbon film after ball-on disk measurement

Nano scale investigation of particulate contribution to diamond like carbon film by pulsed laser deposition

“…DLC is one of the exciting and highly sought aer materials in industrial applications due to its high hardness, high elastic modulus, high electrical resistivity, good eld emission, high thermal conductivity, high optical transparency and high chemical inertness. [1][2][3][4] DLC lms are commonly used for cutting tools, anticorrosion coatings, tribological and electrochemical applications, in addition to various other applications such as protective layers in magnetic storage devices and microelectromechanical systems (MEMS). [5][6][7][8][9][10] The properties of DLC are inuenced by several features like; (a) sp 3 content, (b) H-content, (c) sp 2 cluster phase, (d) sp 2 cluster size, (e) number density of sp 2 cluster, (f) sp 2 cluster phase orientation and (g) any cross-sectional structure, as a consequence of interaction among sp 2 and sp 3 bonding of carbon.…”

“…11,12 The above mentioned factors including chemical bonding of carbon atoms and mechanical properties like elasticity and hardness of the DLC lms depend upon the deposition method and the parameters used therein. 1,2,[13][14][15][16][17] This is because energy of carbon species during deposition plays a vital role in establishing sp 3 /sp 2 phase formation in the DLC lms. 1,2,13 Pulsed laser deposition (PLD) has emerged as a successful deposition techniques to synthesize non-hydrogenated DLC (C-C sp 2 and sp 3 bonding) at room temperature.…”

“…2,14,18 Recently Ruiz et al have studied elastic heterogeneities in nanostructured DLC lms grown with various kinetic energies of ions ablated with an Nd:YAG laser of 1064 nm wavelength. 18 They have also studied sp 3 content variation along the thickness of the DLC lms by angle resolved X-ray photoelectron spectroscopy and observed that sp 3 content is less on the surface as compared to the subsurface region. They found that DLC lms synthesized with lowest kinetic energy (100 eV) of carbon ions with highest thickness (1050 nm) possess highest sp 3 content (40.8%) and all the lms have an elastic heterogeneity extending only to 20 nm diameter size domains.…”

Friction force microscopy study of annealed diamond-like carbon film

“…The deposition time was fixed at 5 min 30 s for each sample to achieve same thickness film of 120 nm. The experimental parameters used in this study were shown in previous work [21]. After the deposition, the DLC film was annealed with the RTP in nitrogen ambient.…”
