About Rhodium Electroplating
Rhodium Electroplating Services
Rhodium is a precious metal valued for its durability, conductivity, and resistance to heat, wear, and corrosion, making it an excellent choice for electroplating. Titan Plating offers specialised rhodium electroplating services, delivering high-quality coatings with a focus on fast turnaround to meet your project deadlines. Our processes ensure reliable performance for components in demanding environments.
Rhodium in Electroplating
Rhodium is a rare, silvery-white metal from the platinum group, known for its hardness, high density, and resistance to oxidation and acids. It provides a durable, reflective coating in electroplating, enhancing the substrate's properties without using rhodium for the entire part. As a byproduct of nickel and copper refining, rhodium offers a cost-effective alternative for high-performance applications.
Benefits of Rhodium Electroplating
Rhodium electroplating offers several advantages:
-
Corrosion Resistance: Provides superior protection against oxidation, acids, and moisture, even in extreme conditions.
-
Hardness and Durability: High hardness ensures resistance to wear, impacts, and scratching.
-
Heat Resistance: High melting point suits applications in high-temperature environments.
-
Electrical Conductivity: Low electrical and contact resistance ideal for electronic components.
-
Aesthetics: Brilliant, reflective silvery-white finish enhances appearance.
Applications of Rhodium Electroplating
Rhodium electroplating is used in various applications:
-
Catalytic Converters: Reduces nitrogen oxides in automotive exhaust systems.
-
Electrical Contacts: Coats connectors for low resistance and durability.
-
Optics: Applied to mirrors and fibres for reflectivity and corrosion resistance.
-
Thermocouples: Measures high temperatures due to heat resistance.
-
Nuclear Reactors: Coats detectors for neutron flux measurement.
Industries Using Rhodium Electroplating
Titan Plating provides rhodium electroplating for diverse industries:
-
Automotive: For catalytic converters and electrical components.
-
Electronics: In contacts, connectors, and semiconductors.
-
Telecommunications: For optic fibres and high-frequency circuits.
-
Aerospace: In thermocouples and heat-resistant parts.
-
Chemical Processing: For acid-resistant coatings in manufacturing.
Rhodium Electroplating Process
Titan Plating employs precise electroplating methods for rhodium:
-
Barrel Electroplating: For small, durable parts rotated in an electrolyte bath for uniform coating.
-
Rack Electroplating: For larger or delicate components secured on racks for controlled thickness.
The process begins with substrate preparation, including polishing, ultrasonic cleaning, and rinsing. An underplate like nickel may be applied. The part is immersed in a rhodium electrolyte solution, and an electric current deposits the coating. Post-plating includes rinsing, steam cleaning, and drying. Our fast-turnaround ensures quality and efficiency.
