The Electrolizing Process

The Electrolizing Thin Dense Chrome process, or Traditional Thin Dense Chrome, is a proprietary electroplating technique that yields a microcracked surface texture and imparts a hard, uniform metallic chromium surface deposit. This uniform, thin layer guarantees that part tolerance and balance are maintained without the necessity for subsequent machining, even when dealing with intricate shapes, all while delivering simultaneous benefits regarding protective qualities and performance improvements.
Armoloy provides two distinct surface textures (Micro Nodular / Micro Cracked), each specifically engineered to address your requirements. Our team of engineers conduct a thorough assessment for each application, enabling them to customize the advantages by choosing the appropriate texture and co-deposits, thus optimizing your component's performance. This proactive approach effectively safeguards against metal failures and elevates machine performance and output efficiency.
