Abstract: The corrosion resistance of transmission gear was studied by covering the surface of transmission gear with multi-layer solid lubricating film. First, the friction characteristics of the solid lubricating film are analysed. Then, the transmission torque of the transmission gear is obtained by the law of conservation of energy, and the relationship between the deflection angle β and the wear depth of the transmission gear is determined. Finally, the corrosion parameters of single-layer solid lubrication film and composite multi-layer solid lubrication film are compared in seawater environment to verify the corrosion resistance of transmission gear. The experimental results show that the multi-layer solid lubricating film can effectively improve the corrosion resistance of transmission gears. When the corrosion time is 12 days, when the BN content is 20wt. % and 30wt. %, the corrosion rate is as low as 0.0050 g/(m²·h) and 0.0037 g/(m²·h) respectively.

Keywords: transmission gear; multi-layer solid lubricating film; corrosion resistance; weight loss method; conservation of energy.
