Passivation

Since 1983, Accurate Burring Co., LLC has provided high-quality deburring, cleaning, and finishing services. One of our key offerings is passivation, an important process that protects stainless steel parts from rust and corrosion. We serve a variety of industries, making sure that parts are treated to withstand harsh environments and maintain long-term performance.

What is Passivation?

Passivation is a metal finishing process that enhances the corrosion resistance of stainless steel. The process involves exposing stainless steel components to a citric or nitric acid solution. This removes iron or iron compounds from the surface, creating a thin oxide layer that prevents rust and corrosion. Citric acid passivation, in particular, is a preferred method for its eco-friendly properties and effectiveness in creating a durable protective layer.

Why Choose Citric Acid Passivation?

At Accurate Burring, we specialize in citric acid passivation for its environmentally friendly benefits. Citric acid is a non-toxic, biodegradable substance that removes contaminants without damaging the stainless steel. It’s ideal for industries looking to maintain sustainability while ensuring the longevity of their parts.

Citric passivation is especially effective in creating a protective layer on stainless steel components exposed to challenging conditions. This layer enhances the parts’ resistance to rust and corrosion, increasing their lifespan and reducing maintenance needs.

Our Passivation Process

Our team uses a variety of tools to guarantee the effective application of citric acid passivation. Parts are submerged in the citric acid solution using stainless steel, polyurethane, and rotating baskets. The baskets come in different sizes to accommodate parts of various shapes and make sure they are securely treated.

We also employ deionized (DI) water tanks, pH readers, hydrometers, and centrifugal spin dryers to monitor and control the passivation process. This helps us maintain precise conditions for every batch and guarantees that the parts are treated to meet the highest standards.

Our passivation knowledge also extends to laser-marked parts; we are well-versed in addressing the unique requirements of these parts and ensuring that the passivation process does not interfere with the laser markings, thereby preserving the marks’ integrity and clarity.

Industries That Benefit from Passivation

Passivation is an essential service in many industries where parts need to be protected from rust and corrosion. Key industries that benefit from citric passivation of stainless steel include:

  • Automotive: Passivation protects vehicle parts from rust, ensuring they last longer and perform reliably.
  • Medical: Stainless steel components used in medical devices need to be free from contaminants. Passivation ensures the safety and cleanliness of these parts.
  • Battery: Battery components are vulnerable to corrosion. Citric acid passivation helps preserve their performance and extend their life.
  • Food Processing: In the food industry, clean equipment is crucial. Passivation removes oils and contaminants, helping to meet hygiene standards.
  • Spring: Springs are often exposed to stress and wear. Passivation improves their strength and durability.

The Benefits of Citric Acid Passivation

Citric acid passivation offers several advantages. It creates a protective oxide layer that enhances the part’s resistance to corrosion. The process also removes contaminants at a molecular level, ensuring a cleaner surface.

By preventing rust and corrosion, passivation helps reduce downtime and repair costs. It also extends the life of parts, leading to fewer replacements and increased reliability.
