Fast & Effective Removal of Free Irons
Ultrasonic passivation is the process of improving the corrosion resistance of stainless steel with the help of cyclic sound pressure. During the passivation process, ultrasonic sound waves drive the citric acid solution deep into the part or parts, removing the free irons allowing for the chromium in the stainless steel to form a thin microscopic shell on the outside of the part. The ultrasonic waves help assist in removal of the free irons by creating motion as the free irons are being removed.
Our Ultrasonic Passivation Services Include:
- Passivation of small or large batches as well as large individual parts
- Passivation using deionized water and citric acid
- Copper sulfate testing of passivated parts
