Abstract
The invention relates to the technical field of railway vehicles, and discloses a steering frame surface treatment method, a steering frame and a railway vehicle. The treatment method comprises the following steps of processing a titanium alloy steering frame by taking a titanium alloy as a material; performing acid pickling on the surface of the titanium alloy steering frame; performing iron ioninspection on the surface of the titanium alloy steering frame; and performing anodizing treatment on the surface of the titanium alloy steering frame. The invention further discloses the steering frame processed by using the treatment method and the railway vehicle comprising the steering frame. According to the steering frame surface treatment method, the steering frame and the railway vehicle,the steering frame is made by taking a titanium alloy as a raw material instead of a carbon steel material in the prior art, and has the advantages of light weight, high strength, good corrosion resistance and good low-temperature impact toughness; and the surface of the titanium alloy steering frame is subjected to the acid pickling, iron ion inspection and anodizing treatment, so that the corrosion resistance, the wear resistance and the weather corrosion resistance of the steering frame of a high-speed train are improved.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a bogie surface treatment method, a bogie and a rail vehicle. Background technique [0002] The EMU bogie is one of the important components of the high-speed rail train, and it is also the key load-bearing part of the train operation. It plays the role of supporting the car body and bearing various loads between the car body and the wheels, and the stress situation is complicated. During the operation of the vehicle, as the vehicle bumps and is subjected to alternating loads, its working conditions are harsh, and its materials are often required to have high strength and stability. my country's high-speed rail will serve in extreme weather conditions in the northern region and exported to Russia and other countries. It is even more necessary for the bogie frame material to have good low-temperature impact toughness, corrosion resistance, and weather corrosion resistance. ...
