| Objective To investigate the engineering application and coating performance about technology of brush cadmium plating of 300M steel in the undercarriage. Methods Cadmium coating with good appearance quality was obtained with two different kinds of brush cadmium plating solutions. The microstructure, thickness, binding force, corrosion resistance, property against hydrogen embrittlement of the cadmium coating were tested by SEM, salt-fog cabinet, mechanics experimental machine and so on. Application study of this technology in brushing electroplating of the undercarriage parts. Results Both of the electroplating solutions used could obtain cadmium coatings with stable quality as well as thickness and bonding force that met the technical requirements on the surface of 300M. The neutral salt spray performance of the cadmium coating was over 500 hours, and the property against hydrogen embrittlement was also qualified. Conclusion The technology of brush cadmium plating can be successfully used in repair of undercarriage parts for a certain type of aircraft. |
