iridiumpäällysteiset

Iridiumpäällysteiset refers to objects or surfaces that have been coated with iridium. Iridium is a dense, hard, and silvery-white metal belonging to the platinum group. Its extreme resistance to corrosion, even at high temperatures, makes it a valuable material for protective coatings.

Iridium coatings are applied through various methods, including electroplating, physical vapor deposition (PVD), and chemical vapor deposition (CVD). The choice of method depends on the substrate material, the desired coating thickness, and the application's requirements.

The primary benefit of an iridium coating is its exceptional durability and resistance to chemical attack and wear. This makes iridium-plated components suitable for demanding environments where other materials would quickly degrade. Applications can be found in aerospace, where iridium coatings protect parts from extreme heat and corrosive gases, and in scientific instrumentation, where its inertness is crucial. It is also used in some high-end jewelry and decorative items for its lustrous appearance and tarnish resistance. The high cost of iridium, however, limits its widespread use to specialized applications where its unique properties are essential.
