What to do if parts fade after hydrogen peroxide low-temperature plasma sterilization - AbleMed.


The hydrogen peroxide low-temperature plasma sterilization equipment operates in a vacuum under low-temperature conditions, utilizing the reactive species of plasma to react with microorganisms. Hydrogen peroxide (H₂O₂) is then employed to act on microbial cells, achieving sterilization. This type of sterilization equipment is primarily used in medical institutions such as operating rooms, laboratories, pharmaceutical factories, and testing facilities.

The medical devices mainly used for hydrogen peroxide low-temperature plasma sterilization equipment:

Hysteroscope, laparoscope, laryngoscope, probe, rigid endoscope, flexible endoscope, ophthalmoscope, fiber optic cable, intracranial pressure sensor, cryotherapy probe, prostate resectoscope, esophageal dilator, electrocautery device, defibrillator, laser probe, metallic items, glass items, silicone items, rubber items, etc.

What should be done if medical instruments undergo fading or corrosion after sterilization?


Inspect the parts where fading and corrosion occur. This fading phenomenon typically happens on metal surfaces that have undergone surface treatments, such as anodized aluminum. Hydrogen peroxide gas reacts with the surface of aluminum, causing a change or fading in color.


Although anodization is aimed at enhancing the surface properties of metals, using the oxide layer to improve their wear and corrosion resistance, and enhancing the quality and appearance of metal surfaces to make them smoother and more uniform, it can also serve a decorative purpose. However, if the materials and processes used are not tailored to the medical environment, such fading can occur. The fundamental reason is that most anodizing factories do not consider hydrogen peroxide low-temperature plasma sterilization as a specific usage scenario in their process standards. In essence, the quantity of these parts is small, the process is complex, and no factory would go to great lengths for this purpose.

If we want to eradicate this corrosion and fading issue at its source, medical device manufacturers must engage in discussions with their parts suppliers. They need to demand changes in their processes and seek solutions from suppliers to ensure that parts do not fade after sterilization. The two main processes that affect part fading are the materials used and the anodizing process (in layman's terms, the chemical solution formula). Alternatively, they can directly seek out factories capable of meeting these process standards.

What is aluminum anodizing?


Aluminum anodizing is an electrochemical process used to enhance the corrosion resistance and surface hardness of aluminum by forming an oxide layer on its surface.

What is the process flow of aluminum anodizing?


The process flow of aluminum anodizing includes cleaning, acid etching, anodizing, and sealing. Firstly, aluminum parts undergo cleaning to remove surface contaminants, followed by acid etching in acidic solution to remove oxide layers and surface oxides. Subsequently, the aluminum parts act as anodes and are immersed in an electrolyte for anodization, forming an oxide layer. Finally, sealing treatment is often conducted to enhance the sealing and corrosion resistance of the oxide layer.
