Preparation and Characterization of Semi-Metal Friction Materials Doping Rare Earths
In order to study the effects of preparation process on the performance and microstructure of the materials, semi-metal friction materials doping rare earths were produced. Different influencing factors in preparation processes (forming pressure, hot- pressing temperature, etc.) were investigated and the optimum technological parameters were selected. The results showed that preparation processes has correlation with the properties of the materials. The morphology of worn surface was observed by scanning electronic microscope, and the conclusion was drawn that wear mechanisms of the materials were mainly abrasive wear, adhesive wear and fatigue wear. Doping RE in the materials can improve the interracial bonding among the components of semi-metal friction materials and make the structure of the materials more impact.
