一、前言以往曾经多次试验采用表面处理的方法来提高气缸壁、活塞环和活塞等工作条件苛刻的发动机零件的配合面的耐磨性,并有不少成功的例子。这些表面处理技术的共同特点是:零件成本增加不大,处理后零件的重量、体积和冷却性能的变化也较小。可以预料这些处理技术今后将会陆续问世,以适应燃料品种的变化和提高燃料经济性的要求。例如绝热发动机就要求有能够经受恶劣的润滑条件的新型配合表面。本文试从这种新型表面处理技术的效果来进行探讨。这种新技术同以往的表面处理方法
I. PREFACE In the past, we have tried many times to improve the wear resistance of engine parts with harsh working conditions such as cylinder wall, piston ring and piston by surface treatment. There are many successful examples. Common features of these surface treatment technologies are: small increase in parts costs, handling parts weight, volume and cooling performance changes are also small. It is expected that these treatment technologies will come out in succession in order to meet the requirements of fuel variety changes and fuel economy. For example, adiabatic engines require new mating surfaces that withstand harsh lubrication conditions. This article tries to explore the effect of this new surface treatment technology. This new technology with the previous surface treatment methods
