Process Flow for Magnesium Alloy Passivation Treatment

Degreasing: Remove grease and contaminants from the magnesium alloy surface using a degreasing agent.
Rinsing: Clean the degreased magnesium alloy surface to remove residual degreasing agents.
Activation/Etching: Treat the magnesium alloy surface with an activator or etchant to enhance surface reactivity.
Surface Conditioning/Bleaching: Further clean and activate the surface using a surface conditioner or bleaching agent.
Passivation/Film Formation: Form a protective oxide film on the magnesium alloy surface.
Rinsing: Clean the treated magnesium alloy surface to remove residual processing solutions.

Applications and Effects of Passivation Treatment for Magnesium Alloys

Through passivation treatment, the corrosion resistance of magnesium alloys is significantly enhanced in most environments, particularly in solutions containing chloride and sulfate ions, where the corrosion rate is greatly reduced. Additionally, passivation treatment improves the stress corrosion cracking resistance of magnesium alloys in alkaline media. This advancement promotes the broader application and development of magnesium alloy materials, enabling them to perform excellently in a wider range of scenarios.
