机车车辆运用强度的提高导致车辆活接部件的强烈磨损和提前损坏。在自润滑工况和振动条件下工作的摩擦部件中采用塑料是特别有效的。所以在金属材料日益短缺的条件下通过创制以聚合物为基的抗磨材料的途径来合理利用聚合物的问题,就变得越来越重要。将聚合物与其它材料复合就可以获得具有各种预定性能的材料系。努力创制兼备聚合物和金属最有用的性能的材料,其结果一定会是研制出金属聚合物系材料。改变聚 The increased use of locomotives and rolling stock causes strong wear and tear of live parts of vehicles. The use of plastic in frictional parts that operate under self-lubricating conditions and vibrations is particularly effective. It is therefore becoming more and more important to rationalize the use of polymers by creating polymer-based abrasion-resistant materials in the face of growing scarcity of metal materials. Materials that have a variety of predetermined properties can be obtained by compounding the polymer with other materials. Striving to create materials that combine the most useful properties of polymers and metals, the result will be the development of metal-polymer-based materials. Change poly
