1,Description:

Inherent corrosion resistance and ease of sterilization are essential to ensure patient safety and equipment life. In addition, the lightweight nature of aluminum reduces the physical strain on healthcare providers when moving medical devices.

It is also cost-effective for mass production, as the initial mold costs cover a large number of units.

2,Applications:

Alkali etching is a basic and important pretreatment in the anodizing of architectural aluminum panels and profiles.Alkali etching yields a detailed etching surface with no glossy satin finish, which is the result of a high percentage of diffuse reflection.Table 3 shows the electrochemical properties of intermetallic compound particles in aluminum alloys during alkali etching.Different intermetallic compounds and even the same compound with different particle sizes can have completely different electrochemical properties.There are two mechanisms for the formation of surface corrosion pits in aluminum alloys due to the presence of the second phase of intermetallic compounds: the second phase acts as a cathode (e.g., Al3Fe) causing the aluminum matrix around the particles to preferentially dissolve; and the second phase of intermetallic compounds particles is an anode (e.g., Mg2Si) relative to the aluminum matrix and preferentially dissolves.The presence of second-phase intermetallic compounds in aluminum alloys, regardless of whether they are cathodic or anodic with respect to the aluminum matrix, results in the formation of corrosion pits on the surface during alkali corrosion, which produces a lightless, diffusely scattered surface.The former forms corrosion pits due to localized dissolution of the aluminum surrounding the second phase; the latter forms corrosion pits due to direct dissolution of the intermetallic compound.Therefore we can expect that the bright effect of chemical or electrolytic polishing is hardly reflected after anodizing of multiphase aluminum alloys.
