摘要
In order to improve the wear resistance of elastic metallic-plastic thrust bearing pad, micro-assembling PTFE/Al2O3 multi-layer film was developed by alternating radio frequency(RF) magnetron sputtering PTFE and Al2O3 targets. For enhancing the adhesion of the interfaces between PTFE and Al2O3 film, N+ implantation was employed. The structure, mechanical and micro-tribological properties were studied by XPS, X-ray photoelectron spectrometer and atomic force and friction force microscope (AFM/FFM). The results show that the multi-layer consists of Al2O3 component and crystalline PTFE. The hardness of the multi-layer modified by ion implantation is less than that of Al2O3,but its toughness is greatly improved. The friction coefficient of PTFE/ Al2O3 multi-layer modified by ion implantation is much lower than that of Al2O3 film, and its resistance to wear is much greater than that of PTFE film. Therefore the wear resistance of elastic metallic-plastic thrust bearing pad is greatly improved.
