| description | The invention discloses an anti-corrosion treatment method for the surface of a bearing outer ring of a railway wagon. The anti-corrosion treatment method comprises the following steps that firstly, the surface of the bearing outer ring is subjected to oil removal, cleaning and drying treatment; secondly, the surface of the bearing outer ring is subjected to sand blasting treatment, so that the cleanliness of the surface of the bearing outer ring is Sa3 level, and the roughness is 10-30 micrometers; thirdly, the surface of the bearing outer ring is subjected to thermal spraying treatment, and a coating is formed; and 4, carrying out sealing treatment on the coating by using a passivation solution. According to the anti-corrosion treatment method for the surface of the outer ring of the bearing of the railway wagon, the anti-corrosion treatment process is simplified, the corrosion resistance of the bearing is improved, the service life of the bearing is prolonged, and the environmental protection property in t |
