The Study of Surface Structure and the Tribological Property of DLC-Modified NBR Elastomers Using DC-MS

The DLC film was prepared on a nitrile rubber (NBR) elastomer by DC magnetron sputtering (DC-MS), and the sp3 ratio of adjusted changing negative bias voltage applied to substrate. microstructure, composition, tribological properties films deposited NBR substrates were systematically investigated. results reveal that surface can protect reduce roughness NBR. While ranges from 0 V −150 V, content increases with an increase in voltage. viscoelasticity substrate will greatly affect film’s adhesion strength behavior.
