现代车用发动机用新材料新工艺

发动机是汽车的心脏。发动机零件的服役条件很恶劣，疲劳、磨损、高温、腐蚀、振动等，时刻威胁着发动机零件的使用寿命。因此，与汽车其他零件相比，发动机零件所用的材料往往要好得多。本文详细地阐述了现代车用发动机各主要零部件用的新材料、新工艺。新材料、新工艺在现代车用发动机上的应用将越来越广泛。

Discuss about New Material and New Technology of Modem Engine

Launch the machine is an automotive heart. Launch the machine spare parts undergoes military service the condition very bad, tired, wear away, heat, decay, vibrate the etc. , threaten the service life of launch the machine spare parts every moment. Therefore, compared with other spare partses of automobile, launch the machine spare parts use of material usually want much better. This text elaborated the modern in detail vehicle- use launch the new material that each main zero partses of machine use, new craft. Lately the material, new craft is vehicle - use to launch in the modern on board application will more and more extensive.
