Hard anodizing for orthopedic components

Hard_anodising_components_blu

In the industry of medical devices, particularly those for orthopedic applications, the quality of components is key. These external fixing devices for the upper and lower limbs, designed to correct the bone structure and treat post-surgical trauma, require materials with very precise dimensions and which are extremely resistant to wear and abrasion. With its black hard-anodizing treatment, Argos ST has played an important role in guaranteeing the reliability and durability of these orthopedic components.

Resistance and precision for orthopedic components

A leading company in the manufacture of orthopedic medical devices, focused particularly on trauma solutions (including external fixing devices designed for the upper and lower limbs) and vertebral stabilisation, found that it needed to improve the resistance of its aluminium components. These orthopedic devices are used by healthcare professionals to treat compound fractures and correct bone structure, with a direct impact on the functional recovery of patients. In such a critical context, it was necessary to apply a coating that could increase the wear and abrasion resistance of moving aluminium components without compromising the extremely high-precision dimensions required for these medical applications.

Black hard anodizing for high resistance

Argos ST proposed a black hard anodizing treatment for these aluminium orthopedic components. Hard coating equipped the devices with optimal wear and abrasion resistance, both essential for them to function properly. Hard anodizing is an electrochemical process that creates a protective layer of oxide on the surface of the metal, making it highly durable and improving its aesthetic properties, without compromising the structural quality of the underlying material. Hard anodizing, applied to aluminium, enabled a greater-than-standard thickness, with a layer of approximately 60 microns. This is significantly more than normal hard anodizing applications which tend to vary from 30 to 50 microns. This treatment left the components more resistant to extreme usage environments, e.g. in contact with the human body, reducing abrasion and wear.

The benefits of hard anodizing for orthopedic components

Use of the hard anodizing treatment offered a host of benefits:

  • Increased resistance: the treated components can be subject to demanding usage conditions without damage. This means abrasion and wear resistance are guaranteed, improving the useful life of the devices.
  • Maintaining precise dimensions: the precision of the treatment and careful control of the entire process made it possible to achieve optimal precision in terms of dimensions, a necessary requirement for orthopedic components.
  • Outstanding finish: the black finish of the hard anodizing treatment ensured the components have a refined, unobtrusive look for lasting aesthetic uniformity.

With its extensive experience in the treatment of metals and its ability to provide custom solutions, Argos ST confirmed its status as the perfect partner for companies manufacturing medical devices. Black hard anodizing has resolved the challenges of wear and precision, offering superior protection. Argos ST continues to represent a benchmark for companies seeking innovative solutions capable of meeting the most challenging technical and manufacturing requirements.
