Problems solved by technology
[0002] Most of the air ducts of rail vehicles in the related art are made of steel materials, and the air ducts of steel materials are of high quality, resulting in high energy consumption of vehicles, which do not meet the requirements of modern vehicle lightweight development
If light metal materials are used, because their strength and rigidity are lower than those of steel materials, there will be major problems in connecting with the steel structure of the car body (such as direct welding with steel), and its own thread strength is low and cannot be directly threaded.
At the same time, there is a large potential difference between light metal materials and carbon steel materials, and electrochemical corrosion is prone to occur when they are in direct contact with each other, resulting in a decline in the performance of the product for a long time and failing to meet the expected design requirements
