Bright, Smooth, Corrosion-Resistant Finishes
APT offers electropolishing of stainless steel and titanium. We specialize in electropolishing industrial metal components for the Semiconductor, Oil & Gas, and Medical industries.
Electropolishing is an electrochemical process which polishes the surface of a metal by removing a microscopic amount of material from the part. The electrochemical process employs an acidic viscous medium for the transportation of ions, allowing surface undulations to form a more planar surface finish. APT’s electropolishing process results in parts that are bright, smooth, and possess a more corrosion-resistant finish.
Benefits of Electropolishing
- Enhanced Surface Appearance: Produces a smooth, bright, and aesthetically appealing finish.
- Improved Cleanliness & Sterilization: Creates a cleaner, smoother surface that is easier to sterilize, making it well suited for medical and other high-purity applications.
- Access to Complex Geometries: Polishes recessed, intricate, and difficult-to-reach areas that may be inaccessible using conventional mechanical polishing methods.
- Precision Material Removal: Removes a controlled amount of surface material while reducing microscopic peaks, burrs, and surface irregularities.
- Enhanced Corrosion Resistance: On stainless steel, preferentially removes surface iron while enriching chromium and nickel at the surface, improving passivation and corrosion resistance.
Unmatched in the Industry
Our ability to electropolish odd-shaped metal parts of virtually any size — with the same outstanding surface finish from lot to lot — is unmatched in the industry.
In order to achieve the desired level of polish and localized areas of polish, the size, position, and distance of the cathode to the part must be precisely controlled. In electropolishing, the metal part is immersed in a temperature-controlled electrolyte bath and connected to the positive terminal (anode) of a DC power supply. The negative terminal is attached to a cathode, to which the particles removed from the metal part are attracted when electric current is applied.
Anodic Process Technologies’ experience and process control result in outstanding electropolishing results for high-performance applications — from surgical instruments to components engineered to withstand harsh downhole environments.
