A diamond-like carbon thin film was coated onto a stainless steel substrate using plasma assisted chemical vapour deposition (PACVD). Instrumented indentation and scratching were used, supported by focused ion beam (FIB) microscopy, to explore deformation and fracture behaviours of this coating system. The formation and growth of ring and radial cracks in the coating, as well as plastic flow in the...
Amorphous carbon coatings (a-C and a-C:H) less than 100nm thick were deposited on KBr, and silicon wafer substrates via magnetron sputtering of a graphite target in argon, argon/hydrogen and argon/nitrogen atmospheres. Electron energy loss spectroscopy (EELS) analysis was used to quantify the sp 2 /sp 3 bonding in the films. Free-standing films of amorphous carbon were produced by...
