Problems solved by technology

[0003] When the car is running, the car frame will be subjected to vertical static load, symmetrical vertical dynamic load, oblique symmetrical dynamic load, other loads, etc., and it will continue to accept the impact of these loads, which will greatly test the fatigue resistance of the car frame. When the anti-fatigue performance of the vehicle frame is not good, it will cause the deformation, cracks and corrosion of the vehicle frame after a long time of use, which will bring serious safety hazards to driving. The anti-fatigue performance of the car frame is general. The surface performance of the car frame is only improved by performing a corresponding heat treatment process on the car frame. However, the effect cannot meet the performance requirements of the car frame, and the corrosion resistance of the car frame is relatively low. Poor, and the working environment temperature of the car frame is generally high, and at the same time it is placed in the external environment for a long time, it is more prone to corrosion behavior, reduces the performance of the car frame, and then shortens the working life of the car frame

The invention discloses a corrosion-resistant automobile frame with an anti-fatigue surface, and relates to the technical field of automobile accessories. Corresponding treatment, at last the car frame is generally strengthened; the car frame with anti-fatigue surface and corrosion resistance provided by the present invention not only has good surface microhardness, but also has good fatigue resistance and surface corrosion resistance performance, can significantly prolong the working life of the car frame and improve its safety.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an automobile frame with an anti-fatigue surface and corrosion resistance. Background technique [0002] The car frame is a frame structure spanning the front and rear axles of the car, commonly known as the girder, which is the chassis base skeleton of the car. On the wheels, the frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car so that each assembly maintains a relatively correct position and Withstands various loads inside and outside the car. [0003] When the car is running, the car frame will be subjected to vertical static load, symmetrical vertical dynamic load, oblique symmetrical dynamic load, other loads, etc., and it will continue to accept the impact of these loads, which will greatly test the fatigue resistance of ...
