近日,在玛帕专题讨论会上,来自欧洲各国130位与会者的重要议题是新加工工艺——热喷涂涂层。这种新的涂层正在逐步代替乘用车缸体上的压装灰铸铁套,使乘用车发动机的生产趋势朝低油耗小型轻型发展。现代铝合金发动机广泛采用灰铸铁衬套生产,以保证其必要的导向性能。然而,成本和生产 Recently, at the Mpa Symposium, 130 important attendees from all over Europe focused on the new processing technology - thermal spray coating. This new coating is gradually replacing the pressed gray cast iron sleeves on the passenger car cylinder body, making the production trend of passenger car engines towards the small and light type with low fuel consumption. Modern aluminum alloy engines are widely used in the production of gray cast iron bushings to ensure the necessary directional performance. However, costs and production
