Ion Implanted AISI 316 Stainless Steel Foil/Sheet
Available Configurations
Properties common to all products in this list
Key Features
Ion Implanted AISI 316 Stainless Steel Foil (UNS S31600) is a molybdenum-bearing austenitic stainless steel foil surface-modified by ion implantation, typically nitrogen or helium ions, to alter near-surface microstructure, improving microhardness, pitting resistance, and corrosion behavior without changing bulk properties:
Improved Microhardness, Pitting Resistance & Corrosion Behavior
Ion implantation alters near-surface microstructure, improving microhardness, pitting resistance, and corrosion behavior without changing the bulk properties of the underlying 316 alloy.
Low-Temperature Process Avoids Thermal Distortion or Sensitization
The ion implantation process creates a modified near-surface layer that resists degradation in chloride-rich and biologically active environments at temperatures too low to induce thermal distortion or sensitization of the substrate.
Retains Bulk Ductility, Formability & Dimensional Integrity
This foil retains the bulk ductility, formability, and dimensional integrity of the 316 alloy while gaining enhanced surface performance from the implantation treatment.
Suited to Biomedical Implant Fabrication
Biomedical implant fabrication benefits from this foil's combination of enhanced surface biocompatibility and corrosion resistance with the proven mechanical performance of bulk 316 alloy.
Surface Performance Enhanced Without Compromising Bulk Properties
This foil's surface performance is enhanced while retaining bulk ductility, formability, and dimensional integrity — suited to ion-sensitive microelectronic packaging where surface properties matter independently of bulk behavior.
Industrial Applications
Ion Implanted AISI 316 Stainless Steel Foil is used across biomedical, vacuum technology, and microelectronics sectors where enhanced surface performance is required while retaining bulk mechanical properties:
- ✦ Biomedical Implant Fabrication
- Used in biomedical implant fabrication, where improved microhardness, pitting resistance, and corrosion behavior from ion implantation enhance long-term performance in biologically active environments.
- ✦ Vacuum Chamber Linings
- Formed into vacuum chamber linings, where the modified near-surface layer resists degradation while bulk ductility, formability, and dimensional integrity remain unchanged.
- ✦ Ion-Sensitive Microelectronic Packaging
- Used in ion-sensitive microelectronic packaging, where surface performance must be enhanced while retaining the bulk properties of the 316 alloy, a combination delivered through the low-temperature implantation process.
- ✦ Surface Chemistry Modification & Biocompatibility Enhancement Research
- Supports studies of surface chemistry modification in austenitic alloys, biocompatibility enhancement through ionic surface engineering, and near-surface phase stability under electrochemical and mechanical loading.
