Abstract: The brass was coated on the surface of titanium ropes by physical vapor deposition(PVD), the effects of titanium substrate surface treatment, brass coating composition, coating thickness and coating profile on adhesion of titanium rope and rubber were studied. The results showed that the effective removal of the surface passivation layer of the titanium substrate and the use of the bottoming transition layer could improve the binding force of the brass coating and the titanium. The binding force between the titanium rope and the rubber increased with the growth of Zn content in the brass coating, and went to growth platform area when the Zn content ≥ 30%. The increase of thickness would reduce the adhesion, while the increase of surface roughness of the rope was conductive to the adhesion.
