Zinc plating, also known as galvanization or zinc coating, is a process of applying a protective layer of zinc to the surface of various metal objects under the ASTM B633. This plating technique offers several benefits, which include:

Corrosion resistance: Zinc is highly resistant to corrosion, making it an excellent protective coating for metal surfaces. The zinc layer acts as a barrier, preventing moisture and other corrosive elements from reaching the underlying metal. This helps to extend the lifespan of the coated object and reduces the risk of rust or corrosion. For example thickness classes: SC3 (severe) 12μm, SC4 (very severe) 25μm.

Enhanced durability: Zinc plating can significantly enhance the durability and longevity of metal objects. By providing a protective layer, it helps to minimize wear and tear, reducing the likelihood of surface damage or degradation. This is particularly beneficial for objects exposed to harsh environments, such as outdoor equipment or automotive components.

Cost-effective: Zinc plating is a relatively cost-effective surface treatment compared to other protective coating options. The process is efficient and can be applied to a wide range of objects, from small screws and fasteners to larger components. Additionally, the availability and low cost of zinc make it an economical choice for many industries.

Paint adhesion: Zinc plating provides an excellent base for paint adhesion. The surface of zinc is receptive to paint, allowing for better bonding and adhesion of the paint layer. This is especially relevant for objects that require additional protection.

Easy application: Zinc plating is a relatively straightforward process that can be applied using techniques, such as electroplating. It can be used on different types of metals, including steel, iron, and brass, providing versatility in application.

Overall, zinc plating offers a range of benefits, including corrosion resistance, enhanced durability, cost- effectiveness, improved aesthetics, paint adhesion, ease of application, and self-healing properties. These advantages make it a popular choice for numerous industries, including automotive, construction, electronics, and consumer goods.

What Are The Best Plating Processes For Corrosion Resistance For Steel?

Corrosion will jeopardize the integrity of components of aircrafts, vehicles, and many other all types of equipment. Paramount Metal Finishing provides metal plating solutions that improve the corrosion resistance of metal parts for the aerospace, military, medical as well as industrial and energy industries. The following brief guide offers the best plating solutions Paramount Metal Finishing offers for corrosion resistance to help you decide which type of plating may best fit your requirements.

Metal Plating For Corrosion Resistance On Steel

Electroless Nickel Ams 2404, Astm B733

Because it does not need electric current, electroless nickel plating takes less time than electroplating processes like hard chrome. This type of metal plating improves corrosion resistance by creating a thick, even coating of nickel onto a metal surface. EN can plate down deep recesses of complex shapes. The protective nickel coating has a high hardness and is able to fill any flaws, making it the best metal plating solution for worn or degraded metal parts. Another advantage of electroless nickel plating is that after the plating process is complete, the metal part is ready to go—there’s no need for further surface finishing, grinding, or machining, unlike with other metal finishes.

Manganese Phosphate Mil-dtl-16232 Type M

Manganese phosphate is the hardest type of phosphate coating, and it provides superior corrosion resistance for steel parts. Unlike other phosphate coatings, manganese phosphate can protect steel parts even after they are broken in. Manganese phosphate coatings absorb lubricants on steel surfaces to enhance corrosion resistance and prevent the galling of parts like bearings, bushings, and fasteners that are subject to wear.

Zinc Nickel AMS 2417, ASTM B841

Zinc platings alone have marginal corrosion resistance, but provide even better protection when alloyed with nickel. Zinc nickel plating protects steel, copper, and brass against high temperatures. It can also minimize galvanic corrosion caused by dissimilar metals. This type of metal plating is commonly used in the aerospace industry for landing gears, flap tracks, and other metal parts. It’s also used widely in the defense, automotive, heavy equipment, and agricultural machinery industries. Zinc nickel is a sacrificial coating and is an environmentally safe alternative to cadmium that offers equivalent and, in some cases, better corrosion resistance.

Benefits of Nitric Passivation
AMS 2700, AMS-QQ-P-35, ASTM A967

Nitric passivation refers to a process in which a metal surface, particularly stainless steel, is treated with a nitric acid solution to remove contaminants and promote the formation of a protective oxide layer. This oxide layer enhances the corrosion resistance of the metal and offers several benefits. Paramount Metal Finishing offers nitric passivation of large and small parts to the following specifications AMS 2700, AMS-QQ-P-35 and ASTM A967.

Here are some of the key benefits of nitric passivation:

1. Corrosion Resistance: Nitric passivation helps to improve the corrosion resistance of stainless steel and other metals. The process removes surface contaminants, such as iron particles and embedded carbon, which can initiate corrosion. By creating a clean and passive oxide layer, the metal becomes more resistant to corrosion from exposure to various environmental factors, including moisture, chemicals, and high temperatures.
2. Surface Cleanliness: Nitric passivation effectively cleans the metal surface, eliminating contaminants such as dirt, grease, oils, and machining residues. By removing these impurities, the passivation process ensures a clean and sanitary surface, making it suitable for applications that require strict hygiene standards. This is why it is commonly used in pharmaceutical, biotechnology, medical and food processing industries where cleanliness is essential.
3. Improved Durability: The formation of a passive oxide layer through nitric passivation improves the durability and longevity of stainless steel. The protective layer acts as a barrier against corrosive substances, preventing them from reaching the underlying metal surface. This helps to prevent pitting, crevice corrosion, and other forms of localized corrosion that can degrade the metal over time, thus extending its lifespan.
4. Regulatory Compliance: In some industries, such as food and pharmaceuticals, regulatory standards and guidelines require the use of passivated stainless steel to ensure product safety and hygiene.
5. Cost Savings: Nitric passivation can contribute to cost savings in the long run. By enhancing the corrosion resistance and durability of stainless steel, the need for frequent repairs, replacements, and maintenance is reduced. It’s important to note that while nitric passivation offers several benefits, handling nitric acid requires expertise and adherence to safety measures to prevent accidents or harm.
