Ion Implanted AISI 316 Stainless Steel Disk
Available Configurations
Properties common to all products in this list
Key Features
Ion-Implanted AISI 316 Stainless Steel Disk (UNS S31600) is a molybdenum-bearing austenitic stainless steel disk that has undergone ion implantation surface treatment to introduce ionic species, typically nitrogen, into the near-surface layer, modifying microstructure and chemistry to enhance surface hardness, wear resistance, and corrosion performance without altering bulk properties:
Enhanced Surface Hardness, Wear Resistance & Corrosion Performance
Ion implantation modifies microstructure and chemistry to enhance surface hardness, wear resistance, and corrosion performance without altering bulk properties, providing surface-specific improvement beyond what standard 316 offers.
Low-Temperature Process Preserves Bulk Toughness
The ion implantation process operates at relatively low temperatures compared with thermal surface hardening methods, preserving the dimensional precision and bulk toughness of the substrate.
Modified Near-Surface Phase Resists Aggressive Environment Degradation
A modified near-surface phase resists degradation in aggressive service environments, providing enhanced durability at the surface where it is most needed without compromising the bulk material.
Bulk Properties Unaltered by Surface Treatment
Bulk properties remain unaltered by the surface treatment, ensuring this disk retains the full mechanical performance and corrosion resistance of standard AISI 316 beneath the modified surface layer.
Suited to Surgical, Orthopaedic & Reactor Instrumentation Parts
Biomedical, nuclear, and chemical processing industries employ this disk in surgical and orthopaedic components and reactor instrumentation parts requiring enhanced surface performance.
Industrial Applications
Ion-Implanted AISI 316 Stainless Steel Disk is used across biomedical, nuclear, and chemical processing sectors where enhanced surface performance is required without altering bulk material properties:
- ✦ Surgical & Orthopaedic Components
- Used in surgical and orthopaedic components, where enhanced surface hardness, wear resistance, and corrosion performance from ion implantation improve durability while preserving bulk toughness.
- ✦ Reactor Instrumentation Parts
- Applied in reactor instrumentation parts, where a modified near-surface phase resists degradation in aggressive nuclear service environments without compromising bulk dimensional precision.
- ✦ Corrosive Media Test Specimens
- Used as corrosive media test specimens, where enhanced surface corrosion performance from ion implantation provides a reliable, reproducible platform for evaluating performance in aggressive chemical environments.
- ✦ Surface Chemistry & Fatigue Resistance Research
- Serves as standardised test specimens for investigating surface chemistry changes, fatigue resistance under cyclic loading, and microstructural stability in corrosive environments, with uniform disk geometry supporting reproducibility across experimental series.
