| Abstract: | Properties of PTFE(Poly Tetra Fluoro Ethylene) is modified by adding the reinforcement of nanometer ZnO with the method of latex commix of mechanical stirring and ultrasonic oscillating, which also produces nanometer ZnO improved PTFE composite. The mechanism of friction and wear property of the bush produced with modified-fluoroplastics under the metal basis is discussed in this paper. Results show that all properties of this kind of bush meet or exceed specified standard requirements, which establishes the foundation for its application on speeding-up railway cars and freight cars. |
