国内外近年来对缸套、活塞环用的材质,进行了大量的研究工作。就合金铸铁而言,出现了如加硼铸铁、加铌铸铁和钒钛铸铁等。也有在钒钛铸铁中,再行加入其他合金元素,如稀土、硼和钨等。其具体效果,说法不一,但是通过几年来的实践证明,钒钛铸铁具有更大的优越性。为了分析比较几种典型材质的耐磨性能和匹配性能,以选择最佳的材质类型, In recent years, domestic and international cylinder liner, piston ring with the material, a lot of research work. In terms of alloy cast iron, appeared, such as boron cast iron, plus niobium cast iron and vanadium titanium cast iron. There are also vanadium titanium cast iron, then add other alloying elements, such as rare earth, boron and tungsten. The specific effects, different opinions, but through years of practice has proved that vanadium titanium cast iron has greater advantages. In order to analyze and compare the wear resistance performance and matching performance of several typical materials to select the best material type,
