Acteron has developed a unique process for the electrodeposition of rhodium. OptiRhodium(tm) is a major breakthrough in characteristics and applications of rhodium coatings. It eliminates problems of ductility, stress cracking, porosity and adhesion traditionally associated with rhodium deposits.

Advantages
• Wear Resistance Greater wear resistance than conventional rhodium due to the OptiRhodium(tm) refined grain structure. Hardness and wear resistance far exceed hard gold.

   

• Corrosion Resistance Highly inert pore-free coatings provide extreme corrosion resistance and are resistant to most process environments including fluoride, chloride, nitrate, sulfate and phosphate exposures. Superb Diffusion Barrier - The strongest barrier available due to its dense, pore-free structure and inherent low metallic diffusion properties. Thin underplate coatings of OptiRhodium(tm) can prevent substrate diffusion through gold outer layers even with prolonged exposure at highly elevated temperatures.

   

• Excellent Ductility Even at high coating thickness due to our proprietary low deposit stress process.

   

• Low Resistivity 4.5 micro-ohm-cm makes OptiRhodium(tm) excellent for electrical contacts and other electrical applications.
• Optimum Reflectivity Our proprietary refined grain structure and uniformity of deposit provide optimum reflectivity.
• Enhanced Adhesion Substrate and underplate bond is excellent due to innovative OptiBond(tm) non-etching activation processes.
• Thermal Stability Highly resistant to chemical oxidation. Melting point exceeding 1950†C.

         Applications
