Electrolytic rhodium plating

Rhodium plating is highly valued for its combination of exceptional properties, particularly its superior wear, abrasion, and corrosion resistance, along with its chemical stability. Renowned for its significant hardness, typically ranging from Hv800 to 1000, it forms a durable deposit. Furthermore, rhodium exhibits the lowest electrical resistance among the platinum group metals, providing low and stable contact resistance. This makes it ideal for use on electrical contacts requiring high surface hardness and exceptional durability. The plating also features a brilliant, permanent reflective appearance. However, it is important to note that the rhodium deposit naturally has high internal stress, meaning cracks can easily occur in thick layers, requiring careful control during the plating process.
