In medical technology, aluminum has a very high utility value as a basic material or alloy, due to its low weight. During anodizing and hard anodizing, the surface finish grows into the workpiece. Despite the low process temperatures, these processes – which occur with precisely defined dimensional changes – create extremely strong bonding forces between the surface finish and the basic material.
HART-COAT®, our hard-anodized coating characterized by extremely fine pores, offers exceptionally high durability, excellent resistance to corrosion, and hardness values of up to 480 HV0.025.
HART-COAT® is used in a range of applications, including to coat fixed-angle rotors of microliter centrifuges. These devices can be found in blood banks and clinical laboratories, where blood and other bodily fluids are centrifuged. In the research area, these centrifuges are used for the extraction of DNA, proteins and enzymes. For weight reduction purposes, fixed-angle rotors are manufactured from aluminum alloys. With a thickness of 40 µm, this hard-anodized layer protects components against corrosion.
