Advantages of zinc alloy plating include good uniformity, high precision of plating thickness control, fine surface, suitable for high coating quality requirements, various post-treatment methods, good processing performance and welding performance, and the ability to produce single-side plated products to meet special requirements. The disadvantages of zinc alloy plating mainly include longer production process, higher requirements for substrate quality, raw materials need to be annealed, higher production costs, energy consumption and cost control are at a disadvantage.
Zinc alloy plating is a technology that uses plating methods to obtain different zinc alloy coatings for specific purposes. Its advantages are mainly reflected in the following aspects:
Good uniformity: Compared to hot-dip galvanizing, electro-galvanizing provides better uniformity of plating and ensures even coverage of the product surface.
High precision of thickness control: Electro-galvanizing is able to precisely control the thickness of the coating to meet the anti-corrosion performance requirements of different products.
Fine surface: The fine surface of electro-galvanized zinc plating is very suitable for products with high coating quality requirements.
Various post-treatments: Electro-galvanized zinc layers have high surface activity and can be subjected to various post-treatments, such as passivation, phosphatization, fingerprint resistance, self-lubrication treatment, etc.
Good processing and welding properties: Electro-galvanized zinc has excellent processing and welding properties and is particularly suitable for products requiring special welding requirements.
Ability to produce single-sided plated products: zinc plating can easily produce single-sided plated products to meet some special requirements.
However, there are some drawbacks to zinc alloy plating:
Longer production process: The need for annealing and re-plating makes the production process longer than hot-dip plating.
Higher quality requirements for the substrate: the raw material needs to be annealed and oiled before re-plating, which requires higher quality of the substrate.
Higher production cost: due to the need for annealing and re-plating, the production cost is relatively high.
Energy consumption and cost control are at a disadvantage: zinc plating to make thick zinc layer of automotive panels has a greater impact on production capacity, which requires an increase in the number of plating tanks, and a greater investment in equipment and consumption of electrical energy.
In summary, although zinc alloy plating has many advantages, its disadvantages need to be considered in practical application to ensure the comprehensive performance and economy of the product.
