一、前言汽套缸是发动机的主要零件之一,它不但能直接影响发动机的使用寿命,而且也直接影响发动机的功率。当前发动机为了增大功率,正朝着大型,高增压方向发展,汽缸套工作条件愈来愈严酷,材质要求也越高,,汽缸套工作面的强化和提高耐磨性,是内燃机制造和使用厂共同关心的重要问题。虽然,从过去到现在一直不断地进行研究,但
First, the prelude Steam cylinder is one of the main engine parts, it can not only directly affect the service life of the engine, but also a direct impact on the engine power. The current engine in order to increase power, is moving in the direction of large, high supercharger, cylinder liner working conditions more and more harsh, higher material requirements, cylinder liner face to enhance and improve wear resistance, is the engine manufacturing and Use important issues of common interest to the plant. Although, from the past to the present has been continuously carried out research, however
