Aluminum anodizing is a surface treatment technique used to enhance the corrosion resistance, hardness, and wear resistance of aluminum products. This process involves immersing aluminum products in an electrolyte solution and inducing an oxidation reaction through electrolysis, forming a layer of oxide film on the surface of the aluminum. This oxide film typically consists of aluminum oxide (Al2O3), which can have a hardness comparable to that of glass.

The main steps of aluminum anodizing include cleaning the aluminum surface, forming an oxide film on the aluminum surface, sealing treatment, and possible post-treatment steps. By controlling parameters such as current density, electrolyte composition, and temperature during the oxidation process, the thickness and properties of the oxide film can be adjusted.

Aluminum anodized colors:

The colors of aluminum anodizing depend on the thickness of the oxide film and the formation conditions. Common colors include black (both glossy and matte), red, green, blue, bronze, gold, transparent, etc. Among these, the main colors suitable for endoscopes are black, bronze, and gold. These colors of aluminum anodizing can maintain their color for a long time in medical sterilization equipment and are not susceptible to corrosion.

Medical endoscopes and black aluminum anodizing:

Due to the potential exposure of medical endoscopes to patient fluids, tissues, secretions, and possible pathogens during use, the risk of cross-infection significantly increases if the endoscopes are reused without proper disinfection. Therefore, to ensure the safety of medical procedures, protect patient health, and maintain the safety of medical personnel, medical endoscopes need to undergo regular disinfection.

Chemical disinfection is one of the common disinfection methods for endoscopes. It involves immersion or spraying of endoscopes with chemical disinfectants (such as hydrogen peroxide, glutaraldehyde, chlorine gas, ethylene acetate, etc.) to kill surface bacteria, viruses, fungi, and other pathogens. However, these disinfectants can also cause damage to endoscope components. For example, strong corrosiveness can damage metal or plastic components of endoscope surfaces exposed for long periods. Some disinfectants, such as hydrogen peroxide, may cause fading of surface treatments on endoscope components.

Black aluminum anodizing offers several advantages compared to oxide films of other colors. Its oxide layer provides aluminum products with higher wear resistance and corrosion resistance, thus extending the product's lifespan. Additionally, the thermal conductivity of black oxide films is stronger, making them perform better in high-temperature environments. The black oxide film has stronger light absorption capabilities, making it suitable for optical devices or optoelectronic equipment, thus enhancing their performance. Black aluminum anodizing demonstrates superiority over oxide films of other colors in various aspects and has a wide range of applications in medical settings.
