Electropolishing is an electrochemical process that removes a thin layer of material from a metal surface, typically stainless steel, to achieve a smooth, shiny, and ultra-clean finish. This process enhances corrosion resistance, reduces surface roughness, and eliminates micro-burrs and contaminants. Often described as “reverse plating,” electropolishing dissolves surface imperfections rather than depositing material, resulting in a uniform and polished appearance.

Electropolishing is utilized across various industries to enhance the performance and longevity of metal components:
Stainless steel, particularly 300 and 400 series alloys, is commonly electropolished to enhance its corrosion resistance and surface finish. While 400-series stainless steel offers increased hardness, it is more susceptible to corrosion. Electropolishing mitigates this by removing surface impurities and promoting a uniform passive layer, combining strength with durability.
Surface Preparation: Removal of contaminants such as oils and oxides through cleaning and rinsing.
Electropolishing: Immersion of the workpiece in the electrolyte bath with controlled current application.
Post-Treatment: Neutralization and removal of residual acids, followed by drying to prevent staining.
Heat Management: Ensure proper tank sizing and cooling systems to dissipate heat generated during the process.
Ventilation: Implement adequate ventilation to handle fumes from acidic electrolytes.
Equipment Maintenance: Regularly clean tanks and replace electrolyte solutions to maintain process efficiency.
Fixture Design: Develop appropriate fixturing to ensure uniform current distribution, especially for complex parts.
