Precious metal plating is used in everyday items around us, from cell towers to ball-bearing surfaces to circuit boards. In space, though, silver plating and gold plating are important barriers that protect vital equipment from the incredibly harsh environment around it – shielding components from extreme temperatures, radiation and other severe stresses.
The harshest of conditions require the highest quality materials and the highest level of precision. At AOTCO Metal Finishing, that’s exactly what we specialize in: precision-finished parts that meet the most demanding needs and regulatory requirements.
To satisfy the growing demand for silver plating services and gold plating for aerospace applications, AOTCO is expanding our silver plating capacity with larger tanks and an in-house team of engineers dedicated to developing solutions for the aerospace industry’s surface finishing challenges. We specialize in the plating of light metals including: Magnesium, Titanium, Beryllium, and their various alloys.
Why Silver Plating in Space?
Electroplating in the space industry is essential. Silver plate in particular offers a range of benefits essential for aerospace and satellite technology, thanks to its chemical composition and more affordable cost than other precious metals like gold.
Silver plating has great electrical resistance while also offering superior anti-galling properties, making it ideal for threaded assemblies prone to friction and wear.
The lubricious nature of silver plating reduces the risk of thread damage and seizing, ensuring smooth operation and longevity in challenging environments like space.
Plus, silver's soldering qualities enhance manufacturing efficiency and reliability.
All those factors make the silver electroplating process desirable for satellite applications, particularly for interior components less susceptible to oxidation.
Take waveguides, for example. The center of the waveguide is electroplated in silver because it’s a material that provides good radio frequency (RF) performance thanks to silver’s electrical conductivity and solderability.
Gold Plating and Other Precious Metals Electroplating
Other metals are also used for aerospace electroplating. Gold plating is often seen on the outside of satellites, for instance, because of gold's reflectivity and corrosion resistance.
Copper plating is also typically used for electronic applications like the circuit boards found on satellites.
When selecting the appropriate precious metal for an aerospace application, several factors are considered, including:
Electrical Resistivity and Conductivity
Metal materials with high conductivity ensure optimal performance and help dissipate heat efficiently. Silver has the highest conductivity of structural metals.
Anti-Galling Properties and Lubricity
In space, where metal components and critical systems are subjected to extreme temperature variations and mechanical stresses, reducing wear and friction ensures smooth operation and longevity.
Soldering and Malleability
Forming a reliable bonding between components and the surface is important, as is the ability to work with the material during manufacturing.
Reflectivity and Light Absorption
Minimizing absorption of solar radiation helps create stable operating conditions, mitigating the risk of overheating and damage.
Corrosion Resistance
A durable barrier protects against corrosion, reducing the need for frequent maintenance and replacement.
Industrial Specifications and Regulatory Requirements
Meeting regulatory requirements and aerospace specifications with a NADCAP-certified vendor is table stakes.
Cost Efficiency
While gold plating remains an option for certain applications, the higher cost often steers preferences towards silver, given its comparable performance and relative cost-effectiveness. Look for the right silver plating specifications for a cost-effective plating solution and process.
