Aerospace & Defense Plating Solutions
Engineered precious metal plating for mission-critical components operating in extreme aerospace and defense environments.
What Is the Aerospace & Defense Industry and Why Plating Matters?
The aerospace and defense industry includes systems and components used in aircraft, spacecraft, military equipment, and advanced defense technologies. These applications demand extreme reliability, as components must perform under high stress, temperature variation, vibration, and exposure to harsh environments.
Metal plating plays a critical role in enabling these systems to function as intended by improving conductivity, corrosion resistance, wear performance, and environmental protection without increasing component size or weight.
Key Functions:
- Electrical conductivity for signal and power transmission
- Corrosion resistance in aggressive environments
- Wear resistance for moving and contact surfaces
- Thermal and environmental protection
- Thin, conformal coatings for weight-sensitive designs

Engineering Challenges in Aerospace & Defense Components
Aerospace
Corrosion Resistance in Extreme Environments
Problem:
Aircraft components are regularly exposed to harsh conditions like high humidity, saltwater, extreme temperatures, and chemical exposure, leading to corrosion and degradation of parts.
Solution:
Selective plating allows precise application of corrosion-resistant coatings (such as nickel or gold) to critical areas of aerospace components, protecting them from these harsh environments without adding unnecessary weight.
Wear and Friction in Moving Parts
Problem:
Aerospace components like landing gear, actuators, and engine parts experience high wear and friction due to continuous operation, leading to degradation over time.
Solution:
Selective plating can be used to apply wear-resistant coatings (like hard chrome or electroless nickel) to reduce friction, extend the life of moving parts, and improve performance under extreme operating conditions.
Surface Fatigue and Cracking
Problem:
Aircraft parts such as turbine blades, shafts, and bearings are subjected to cyclic stress and fatigue, which can lead to surface cracks, pitting, and eventual failure.
Solution:
Selective plating with materials like nickel can enhance the surface hardness and fatigue resistance of these components, improving their durability and preventing premature failure.
Electrical Conductivity and Shielding
Problem:
Aircraft require reliable electrical connections and electromagnetic interference (EMI) shielding to protect sensitive avionics and electronic systems.
Solution:
Selective plating of metals such as gold, silver, or copper on connectors, wiring, and critical components can improve electrical conductivity and provide EMI shielding, enhancing the reliability and performance of onboard electronics.
Component Repair and Maintenance
Problem:
Replacing worn or damaged aerospace components can be expensive and time-consuming, especially for hard-to-reach areas or complex parts.
Solution:
Selective plating offers an effective way to repair worn or damaged components in situ, restoring their functionality without needing to replace the entire part. This can significantly reduce maintenance downtime and costs, particularly in high-value parts like engine components.
Thermal Management
Problem:
Aerospace systems often operate at extreme temperatures, particularly in engines and propulsion systems, leading to issues with thermal expansion, overheating, and material degradation.
Solution:
Selective plating with materials like silver or gold can enhance the thermal conductivity of components, helping to dissipate heat more efficiently and manage thermal stresses in critical areas.

Defense
Corrosion in Harsh and Diverse Environments
Problem:
Military equipment often operates in extreme environments, including marine (saltwater), desert (sand and dust), and arctic conditions, leading to accelerated corrosion and degradation of components.
Solution:
Selective plating with corrosion-resistant materials like nickel can protect critical areas from environmental damage, extending the life of weapons systems, vehicles, and communication devices. This is particularly useful for naval vessels, aircraft, and ground vehicles.
Wear and Abrasion of Moving Parts
Problem:
Defense equipment such as firearms, tanks, helicopters, and drones experience high levels of wear and friction due to heavy use, impacting performance and reliability.
Solution:
Selective plating with wear-resistant coatings such as electroless nickel can significantly increase the durability of moving parts like bearings, gears, and hydraulic systems, reducing maintenance costs and extending operational life.
Electrical Conductivity and EMI Shielding
Problem:
Reliable electrical connections and shielding from electromagnetic interference (EMI) are critical for military communication systems, avionics, radar, and weaponry, where failures can compromise operations.
Solution:
Selective plating with highly conductive materials such as gold, silver, or copper can improve electrical performance and EMI shielding on connectors, circuitry, and communication devices. This ensures reliable functionality in critical battlefield conditions.
Component Fatigue and Structural Integrity
Problem:
Defense components, including aircraft parts, missile systems, and armored vehicles, undergo extreme stress and fatigue, which can lead to cracks, deformation, or catastrophic failure.
Solution:
Selective plating with materials like nickel can enhance the surface hardness and fatigue resistance of structural components, improving their ability to withstand mechanical stresses, shocks, and vibrations over long-term use.
Costly Repairs and Maintenance Downtime
Problem:
Military equipment often operates in remote and challenging environments where logistics and repairs are costly and difficult. Replacing components or equipment can lead to significant downtime.
Solution:
Selective plating can be used to repair worn or damaged parts in situ, such as landing gear, gun barrels, and engine components. This reduces the need for full replacements, cutting down on costs and minimizing equipment downtime during field operations.
Thermal Management
Problem:
Military systems like engines, weapons, and electronics are subject to extreme heat during operation, which can lead to overheating, material degradation, and reduced efficiency.
Solution:
Selective plating with thermally conductive materials, such as silver, can improve heat dissipation, protecting critical components from overheating and improving the overall thermal management of systems.
Stealth and Radar Absorption
Problem:
In modern warfare, stealth and reducing radar visibility are critical for aircraft, drones, and naval vessels. Uncoated materials can reflect radar signals, making vehicles and equipment more detectable.
Solution:
Selective plating with materials that absorb or scatter radar signals, such as silver, copper, or nickel, can help reduce the radar cross-section of defense assets, enhancing their stealth capabilities without compromising structural integrity.
