前 言 本文述及对缸套内表面最终加工的要求,考核什么是所希望的和为什么?以及为什么仍然最广泛使用灰铸铁?并对铸铁及其表面处理的变化,对铝合金和高承载陶瓷的择优作出了评价。 对于铸铁,A型石墨具有最佳的抗拉缸性,对最佳耐磨性所要求的石墨形式也决定于基体和其它复合物(如碳化物)的存在。Bruni和Fazzina认为A+B混合型结构可改善耐磨性。然而在缸套使用前,它必须通过制造的各个阶段,包括表面最终加工。当装上内燃机后),它必然遇到外加的磨合条件,这类条件正变得采用更短的持续时间,因而增加了严酷性。对于这些要求和条件来说,A型或主要的A+B型石墨显示了一定的优点。
Preface This article addresses the requirements for the final machining of the inner surface of the cylinder liner, examining what is and what is desired and why it is still the most widely used gray cast iron, and on the changes in cast iron and its surface treatment, on aluminum alloys and on highly loaded ceramics Preference made a comment. For cast iron, type A graphite has the best cylinder resistance and the graphite form required for optimum wear resistance also depends on the presence of matrix and other compounds such as carbides. Bruni and Fazzina that A + B hybrid structure can improve the wear resistance. However, before the liner is used, it must pass through the various stages of manufacture, including surface finish. When fitted with an internal combustion engine), it inevitably encounters additional in-run conditions that are becoming shorter and longer, thus increasing the severity. For these requirements and conditions, Type A or Major A + B graphite shows some advantages.
