Case Study of Functional Characteristics Improvement of Silvec: Case 3

We will introduce examples of how we have solved the functional characteristics challenges faced by our customers and cases adopted through VE proposals. Case 3: Direct Chromate for Zinc Die Casting (for rust prevention) ■ Automotive Parts Manufacturer Company A Due to the very strict dimensional tolerances of the zinc die casting (ZDC1) products, it was not possible to apply electro-zinc plating. We received an inquiry from a customer who was looking for a company that could achieve "no white rust formation after 50 hours in the JIS neutral salt spray test" using trivalent chromium-based direct chromate on zinc die casting. After evaluating our prototype of direct chromate, we cleared the "no white rust formation after 50 hours in the JIS neutral salt spray test" and proceeded to mass production.

Is trivalent chromium plating different from trivalent chromate? [Explained in a video]

Is trivalent chromium plating different from trivalent chromate? [Explained in a video]

Is there a difference between trivalent chromium plating and trivalent chromate treatment at Silvec?

Q: Is trivalent chromium plating different from trivalent chromate? A: Yes, they are different. Trivalent chromium plating is typically applied over nickel plating, and the base material can be any metal that can be plated. However, trivalent chromate is generally applied after zinc plating, although we can also apply trivalent chromate directly to aluminum.

Is chromate treatment necessary after zinc plating?

Is chromate treatment necessary after zinc plating?

Is chromate treatment necessary after zinc plating of Silvec?

Q: Is chromate treatment necessary for zinc-coated surfaces? A: In the case of electro-galvanized coatings, chromate treatment is applied to most products after zinc plating. Zinc coatings are very prone to rust. For zinc plating on iron materials, the zinc coating helps to delay the onset of red rust by corroding (forming white rust), which prevents the occurrence of red rust. Chromate treatment is performed to prevent the formation of white rust (for rust prevention purposes). The corrosion resistance against the formation of white rust depends on the performance of the chromate coating.

Hexavalent chromium treatment

Hexavalent chromium treatment

The most effective chromate treatment (target materials: aluminum and zinc)

This is a chemical treatment that has been most commonly used due to its high processing effects (improvement of rust prevention, corrosion resistance, and paint adhesion). It is ideal for components that require high durability, such as outdoor parts.

Chromate treatment (pre-treatment for painting) .com @ Eiwa Kogei Co., Ltd.

Pre-treatment for painting aluminum (aluminum die casting) and zinc die casting, which are difficult for paint to adhere to.

When high quality and adhesion are required for the painting of aluminum (die-cast) and zinc die-cast products, we adopt "chromate treatment," which is a pre-treatment for painting aluminum (zinc). By applying "chromate treatment" to aluminum materials and zinc die-cast products, which are considered difficult for paint to adhere to, we can impart "high adhesion" and "high corrosion resistance." These non-ferrous metal materials often encounter adhesion issues during painting. It is necessary to align the required quality and painting specifications during the design phase of the painting process.

Zinc-nickel alloy plating with trivalent chromate treatment (white)

Zinc-nickel alloy plating with trivalent chromate treatment (white)

Compared to zinc plating, zinc-nickel alloy has about four times the corrosion resistance until red rust occurs!

We would like to introduce our processing of "Zinc-Nickel Alloy Plating and Trivalent Chromate Treatment (White)." Zinc-nickel alloy plating possesses excellent corrosion resistance by incorporating 5-8% nickel into zinc plating. Additionally, in salt spray tests, zinc-nickel alloy shows approximately four times the corrosion resistance compared to zinc plating before red rust occurs. This corrosion resistance makes it widely used in important automotive components and cold climate specifications. 【Features】 ■ Contains 5-8% nickel in zinc plating ■ High rust prevention (Salt spray test: over 1000 hours before red rust) *For more details, please download the PDF or feel free to contact us.

Zinc plating and trivalent chromate treatment (white and black)

Zinc plating and trivalent chromate treatment (white and black)

By applying a chromate treatment, the formation of white rust on the zinc plating can be prevented!

We would like to introduce our processing of "Zinc Plating and Trivalent Chromate Treatment (White and Black)." The corrosion protection effect of zinc plating is called "sacrificial protection," which utilizes the property that zinc corrodes before iron, thereby protecting the product from rust. Additionally, by applying chromate treatment, we can prevent the occurrence of white rust on the zinc plating film. 【Features】 ■ Rust resistance (Salt spray test red rust for over 240 hours) ■ By applying chromate treatment, it is possible to prevent the occurrence of white rust on the zinc plating film. *For more details, please download the PDF or feel free to contact us.
