Abstract :
Ultra-low coefficient of friction with a statistically averaged value of 0.0067 was observed during the tribological test on TiC/a-C composite coating synthesized by gas–solid interaction of Ti metal with CH4 gas in a thermogravimetric analyzer. Ultra-low friction behavior appeared due to transformation of D-band associated with disordered carbon lattice obtained at lower synthesis temperatures (1050 and 1150 °C) to graphitic G-band mode, which steam from ordered atomic layering occurring at higher synthesis temperature of 1250 °C.
