拖拉机履带板是一种重要的易损零件。在田间作业时,它主要承受低应力磨料磨损。在这种使用条件下。寻找更合适的材料以代替或补充高锰钢是我国工业和科技工作的一个重要任务。本文概述了我国在这方面已进行的主要工作;介绍了一种模拟磨损试验机及根据它作出的磨损曲线。文章还对几种材料的磨损面进行了分析,并探讨了磨损机理。 Tractor track shoes are an important and vulnerable part. When working in the field, it mainly suffers from low stress abrasive wear. Under these conditions of use. Finding more suitable materials to replace or supplement high manganese steel is an important task for our country’s industrial and technological work. This article provides an overview of the major work our country has done in this area. A simulated wear tester is presented, along with the wear curves it produces. The article also analyzes the wear surface of several materials and discusses the wear mechanism.
