Ion Implanted AISI 316 Stainless Steel Foil

Ion Implanted AISI 316 Stainless Steel Foil combines the robust mechanical properties of traditional 316L stainless steel with surface enhancements introduced through nitrogen or helium ion implantation. This technique modifies near-surface layers at the atomic level, improving microhardness, pitting resistance, and overall corrosion behavior without altering the bulk structure. The implanted layer forms a metastable single phase—typically an iron nitride or helium-altered structure—that resists degradation in chloride-rich environments. Used widely in biomedical implants, aerospace structures, and vacuum chamber linings, this material supports critical applications like orthopedic prostheses, cryogenic seals, and ion-sensitive microelectronic packaging. Its demonstrated biocompatibility and reduced corrosion current density (as low as 0.0689 mA/cm² for helium implants) reinforce its value in medical and high-precision environments. Ion implantation offers a low-temperature, layer-free alternative to coatings, positioning this foil as an advanced surface-engineered material for the next generation of bio- and electrochemical interfaces.
