Tribological Properties of the DLC/SEBS/A187/Si Elastomeric Nanocomposite Multilayer Film
A DLC/SEBS/A187/Si multilayer was prepared by self-assembled monolayer (SAM) method and pulse filtered catholic vacuum arc source (FCVA) technology. Microstructure and frictional properties of the film were investigated by using X-ray photoelectron spectroscopy (XPS), AFM, SEM and UMT-2MT tribometer. Results showed that the peaks appearing at 287.8eV for XPS demonstrated the successfully graft of SEBS on the couple agent(A187); The surface of the top DLC film was compactly and uniformly distributed; Friction coefficient of the prepared film was not sensitive to velocity under low load and the coefficient ranged from 0.1 to 0.15, but at high load, the tribological property of the film deteriorated with the increasing of sliding velocity, when the normal load was 2N and the sliding speed was 30 r/min, only the top DLC film was scratched out, but when the sliding velocity increased to 240 r/min, the whole prepared film was scratched out.
