Mechanical and tribological properties of TiC/amorphous hydrogenated carbon composite coatings fabricated by DC magnetron sputtering with and without sample bias

Ceramic TiC/a:C protective nanocomposite coatings: Structure and composition versus mechanical properties and tribology

“…6a [5,6,9,40,41]. It is worth to mention that in the work of Hu et al [37] similar trends of hardness, elasticity and CoF values depending on the elemental composition were presented.…”

Effect of bias voltage on microstructure and properties of Ti-doped graphite-like carbon films synthesized by magnetron sputtering

“…[13][14][15]. An example of such metal-containing DLC films are the Ti-DLC films which have shown reduced internal stress and improved adhesion strength on substrates [16,17]. On the other hand, the a-C films which are predominantly composed of graphite-like structure (sp 2 bonds) rather than diamond-like structures (sp 3 bonds).…”

Tribological behaviour of titanium carbide/amorphous carbon nanocomposite coatings: From macro to the micro-scale

“…Also, the observation of the cracks by high resolution scanning electron microscopy revealed that sliding cavitation were maintained in the nanometric regime due to the reduced size of the grains and enhanced mobility of boundaries. Many groups have later synthesised TiC/C tough composites for tribological applications [14][15][16][17][18][19][20] although the correlation of the friction properties with their chemical composition is quite unclear. Thus, for instance, Gulbinski et al [15] finds friction a variation from 0.6 to 0.1 when total carbon content increases with a plateau around 0.45 for medium contents.…”
