At ADV Plating, we work with companies in all industries to provide the best surface finishes that meet their specific requirements. Surface finishing is the last step in the manufacturing process and directly impacts the functionality, durability, and performance of the parts and components used. Industries have unique and specialized requirements for their final surface finishes due to both regulatory standards and unique environmental stressors that are at play. Our team at ADV Plating can assist you in determining the best material to plate your products to ensure longevity and functionality over time. Let’s take a look at several industries that rely on surface finishes and plating.
Aerospace and Defense
The aerospace and defense (A&D) industries have stringent demands when it comes to surface finishes. These finishes are required to guarantee optimal durability, reduce friction, and offer formidable resistance to corrosion. Such properties are especially crucial given that aircraft and military hardware often endure extreme environmental conditions, such as high heat & sub-freezing cold, salt water, and even the vacuum of space. Additionally, A&D industries must comply with a multitude of governmental agencies, both domestically and internationally.
In the aerospace and defense sector, some of the prevalent Surface Finishes include:
- Anodizing: This is a commonly utilized finish for aluminum components owing to its ability to form a resilient layer of oxide that effectively resists wear and corrosion. It is typically used for critical parts such as the landing gear and the structural elements of the airframe, providing them with a robust protective barrier.
- Electroless Nickel Plating: This kind of finish is recognized for offering a uniform coating thickness, safeguarding the underlying material against wear and degradation due to corrosion. It’s a popular choice for complex shapes and designs, making it an indispensable option for high-wear aerospace components that require reliable protection.
- Chemical Conversion Coating (Alodine): This unique finish stands out for its ability to provide resistance to corrosion without affecting the electrical conductivity of the material. It’s typically applied to aluminum surfaces used for avionics and structural components, ensuring they remain corrosion-free and retain their electrical performance.
- Ceramic Coatings: Known for their high-performance credentials, these finishes are ideal for reducing friction and enhancing the wear-resistance of components. These include crucial parts like engine elements, which demand superior thermal protection in high-stress situations. The ceramic coating ensures these components can withstand challenging environments while maintaining both their functionality and lifespan.
Firearms
In the firearms industry, surface finishing is critical to prolonging the longevity of moving parts by increasing wear resistance, reducing friction, and protecting against corrosion. Given the emphasis on reliability and precision, it is important that these finishes are robust enough to endure harsh conditions while not altering the geometry and sizes of parts.
Here’s a close look at widely used Surface Finishes for Firearms:
- Parkerizing (Phosphate Coating): This is a matte finish that provides an anti-corrosive layer, enhancing oil retention and safeguarding the steel components of the firearm. Due to these qualities, it enjoys considerable popularity in the production of military-grade firearms and the restoration of vintage weapons.
- Black Oxide: An age-old and traditional finish that serves dual purposes – minimizing light reflection and acting as a safeguard against corrosion. It’s frequently used on barrels, slides and other steel parts due to its protective nature.
- Cerakote: This is a ceramic-polymer coating that has gained a reputation for its toughness, its customizability, and its resistance to corrosive agents, harsh chemicals, and impact. These features make it a preferred choice for gunsmiths, who also view its vast color range and superior protection as big advantages.
- Hard Chrome Plating: This finish offers a sleek and wear-resistant exterior, making it ideal for components such as bolts and barrels that undergo heavy usage and need a low-friction surface.
- Electroless Nickel w/ PTFE: EN with a PTFE (Teflon) co-deposit offers increased hardness,resistance to corrosion, and a very low coefficient of friction. These characteristics are well suited for internal parts such as firing pins, triggers, and bolt carrier groups.
Medical Industry
In the field of healthcare and medicine, the importance of surface finishes cannot be overstated. The right finish can ensure sterility, promote compatibility with the human body, and extend the lifespan of medical devices. The devices need to be durable, capable of enduring sterilization procedures, while simultaneously maintaining a low friction and exhibiting no reaction with body tissues or fluids.
Key Surface Treatments for Medical Equipment:
- Electropolishing: This is a meticulous process designed to smooth and pacify metal surfaces. Electropolishing accomplishes two key things: it drastically reduces micro-roughness and eliminates impurities. The process is extensively utilized on stainless steel surgical tools and implants, guaranteeing cleanliness and boosting resistance to corrosion.
- Passivation: This is a chemical process tailored for stainless steel and titanium that eliminates free iron on its surface and amplifies the material’s inherent resistance to corrosion. Instruments that will be exposed to bodily fluids often undergo passivation, which is essential for maintaining their longevity and effectiveness.
- Titanium Anodizing: This process is employed to coat implants and enhance the oxide layer on titanium components. The result is improved wear resistance and biocompatibility, making this finish a popular choice for orthopedic and dental implants.
- Electroless Nickel Plating: Many medical devices use brass components. Electroless nickel adds a hard durable surface to brass, which is naturally soft, thus extending the lifespan of parts. In addition, EN is resistant to a wide range of chemicals, making it ideal for medical environments where sterilization and cleaning agents are used. It also meets many biocompatibility requirements in applications that come into contact with patients.
