机车车辆零件修复的经济效益在于可使大量零件在磨损的工作表面修复后又可以重新使用,同时金属的损耗很小。采用合理的磨损表面增厚方法不仪可以恢复工作表面的尺寸和形状,而且还可提高其大犬多数表面的耐磨性,与制造新备件相比,零件修复可以大大减少材料的消耗,因 The economic benefit of locomotive and vehicle part repair is that it allows a large number of parts to be repaired and then re-used on worn work surfaces, with minimal metal loss. Using a reasonable method of wearing surface thickening not only restores the size and shape of the working surface, but also improves the wear resistance of most of its large dogs, which can significantly reduce the material consumption compared to the manufacture of new spare parts.
