The impact of surface treatment on the properties of magnesium alloys is multifaceted. The following are some specific impacts:

Corrosion resistance
Improve corrosion resistance: Surface treatments, such as anodizing, chemical conversion treatments and coatings, can form a protective layer on the surface of magnesium alloys, effectively isolating the alloy from contact with the external corrosive environment, thereby significantly improving its

corrosion resistance.
Extended service life: By reducing corrosion, surface treatment can extend the service life of magnesium alloy parts, especially in harsh environments such as high humidity and salt spray.

Wear resistance
Enhanced wear resistance: Surface treatments such as coating and electroplating can form a hard protective layer on the surface of magnesium alloy to reduce wear, especially in components with frequent contact friction, such as bearings, gears, etc.

Aesthetics
Improve appearance: Processes such as anodizing, coating, and electroplating can provide different colors and glosses, improve the appearance of products, and meet consumers' needs for aesthetics.
Decorative effect: Surface treatment can provide various textures and patterns to increase the decorativeness and design of the product.

binding force
Improve coating adhesion: Chemical conversion treatment and pretreatment before electroplating can clean and activate the magnesium alloy surface, improve the adhesion of subsequent coatings or plating, and prevent the coating from peeling off.

Electrochemical properties
Improved electrochemical properties: Surface treatments can change the electrochemical behavior of magnesium alloys, reducing the risk of galvanic corrosion, especially when in contact with other metals.

Thermal properties
Improved thermal conductivity: Certain surface treatment processes, such as anodizing, may affect the thermal conductivity of magnesium alloys, which needs to be considered in applications that require good thermal conductivity.

Mechanical properties
Improve strength and hardness: Some surface treatment processes, such as anodizing, can improve the surface hardness and strength of magnesium alloys to a certain extent.
Maintain toughness: Proper surface treatment can provide protection without significantly reducing the toughness of the alloy.

Antibacterial properties
Confer antibacterial properties: Specific surface treatments, such as adding antibacterial agents to the coating, can impart antibacterial properties to the surface of magnesium alloys, which is particularly important in applications such as medical devices.

Electronic performance
Electromagnetic shielding: Certain surface treatments, such as conductive coatings, can improve the electromagnetic shielding effect of magnesium alloys, which is very important in electronic devices.
In summary, surface treatment has a significant impact on the performance of magnesium alloys, not only improving its corrosion resistance and wear resistance, but also improving appearance, bonding strength, electrochemical properties, thermal properties, mechanical properties, and antibacterial properties. and electronic properties, thus broadening the application scope of magnesium alloys.
