Paramount Metal Finishing is a Zinc Phosphating specialist to TT-C-490 Type I and MIL-DTL-16232 Type Z (Classes 1-3). Zinc phosphating is a chemical conversion coating process applied to steel and other metals. It offers several benefits, particularly in Military and industrial applications.

Benefits of Zinc Phosphating:

1. Corrosion Resistance

• Primary benefit: It enhances the corrosion resistance of metals, especially steel.
• Works as a protective barrier and helps retain paints and oils that further prevent rust.
• Often used as a pretreatment before painting or CARC coatings.

2. Improved Paint Adhesion

• Zinc phosphate coatings create a microscopic, porous surface that allows paint and other coatings to bond more effectively.
• Prevents paint peeling and flaking, especially in harsh environments.

3. Wear and Friction Reduction

• It reduces metal-to-metal contact, improving lubrication retention.
• Useful in parts where sliding or movement occurs (e.g., mechanical assemblies).

4. Base for Further Coatings

• Acts as a solid base layer for additional coatings like CARC paint and powder coating
• Oil or wax-based rust preventatives
• Offers a uniform coating thickness

5. Produces a consistent and even coating, important for:

• Maintaining tolerances
• Aesthetic finish
• Functional reliability
• Cost-Effective and Scalable
• Suitable for mass production and widely used in military, automotive, appliance, and heavy equipment industries.

Zinc phosphating offers is cost effective compared to other high-performance coating methods. It offers an enhanced aesthetic finish with a matte gray appearance that can serve as a final finish in some applications.

High Corrosion Resistant Alternative to Cadmium
AMS 2417 ASTM B841 ASTM F1941

Paramount Metal Finishing offers ZINC NICKEL plating to AMS 2417 and ASTM B841 on large parts up to 9 feet in length. Zinc nickel plating as the name suggests is a co-deposited coating of zinc and nickel.

Zinc Nickel is a high performance finish that offers maximum corrosion resistance especially for components used in severe environments. The zinc and nickel alloying creates a distinctive composition that will corrode at a much slower rate than zinc. The combination of approximately 10-15% nickel and the remainder zinc, can offer up to 10X the protection of traditional zinc plating.

Paramount Metal Finishing Zinc Nickel plating benefits:

• Maximum corrosion resistance
• Salt Spray 500+ hours
• RoHS Compliant
• Increased part life span
• Alternative to cadmium and hot dip galvanizing
• Trivalent, Hexavalent and Black Chromates available

ASTM B733, AMS 2404, MIL-C-26074

Electroless nickel plating or autocatalytic nickel plating is a widely used surface finishing process that offers several advantages over other plating techniques. Specifications for EN are ASTM B733, AMS 2404 and MIL-C-26074. Here are some of the key benefits of electroless nickel plating:

Uniform and Consistent Coating: Electroless nickel plating provides a uniform and consistent coating on complex geometries, including internal surfaces, corners, and recesses. It deposits a uniform layer of nickel onto the substrate, regardless of its shape or size, ensuring an even coating thickness.

Corrosion and Wear Resistance: Electroless nickel coatings offer excellent corrosion resistance, protecting the underlying substrate from rust, oxidation, and chemical attack. The deposited nickel layer acts as a barrier, preventing the substrate from being exposed to the corrosive environment. Additionally, electroless nickel coatings provide good wear resistance, enhancing the lifespan and durability of the treated parts.

Hardness and Surface Hardness: Electroless nickel plating can produce coatings with varying levels of hardness, ranging from relatively soft to very hard, depending on the specific formulation and process parameters. This allows the plating to meet different requirements, including wear resistance, load-bearing capacity, and dimensional stability. Electroless nickel coatings can also be heat treated to further increase their hardness and surface hardness.

Thickness Control: Electroless nickel plating enables precise control over the coating thickness. The process parameters can be adjusted to achieve the desired thickness, ensuring consistent results and meeting specific engineering requirements.

Excellent Adhesion: Electroless nickel coatings exhibit excellent adhesion to a wide range of substrates, including metals, alloys, ceramics, and some plastics. This adhesion ensures that the coating remains firmly attached to the substrate, even under harsh operating conditions or thermal cycling.

Lubricity and Low Friction: Electroless nickel plating can provide a self-lubricating surface, reducing friction and wear in sliding or rotating applications. By incorporating certain additives or incorporating post-plating treatments, the coefficient of friction can be reduced, resulting in improved performance, reduced energy consumption, and extended service life.

Versatility: Electroless nickel plating is a versatile process that can be used in various industries and applications. It can be applied to a wide range of materials, including steel, aluminum, copper, brass, and more. The plating can be customized to meet specific requirements, such as high phosphorous coatings for increased corrosion resistance or low phosphorous coatings for solderability.

Paramount Metal Finishing offers electroless nickel in rack and barrel processes.

Overall, electroless nickel plating provides numerous advantages, including uniform coating, corrosion and wear resistance, hardness control, excellent adhesion, lubricity, versatility, and cost-effectiveness. These benefits make it a popular choice for a wide range of applications, from automotive and aerospace to electronics and medical equipment.

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.
