What is Plasox®?
Plasox® is a proprietary plasma-based nitriding post-oxidation surface treatment that produces a protective coating resistant to aggressive environmental conditions. The most critical factor of the Plasox® process is controlled oxidation, where pure magnetite is formed, providing exceptional corrosion resistance.
Advantages of Plasox®
Corrosion Protection
Protection from rust and other forms of corrosion.
Wear Resistance
Improved wear resistance for demanding industrial applications.
Reduced Friction
Enhanced anti-friction properties for moving and sliding components.
Black Finish
Provides an aesthetically pleasing black appearance.
Surface Integrity
No surface pitting, flaking, or hydrogen embrittlement.
Salt Spray Resistance
Easily surpasses 150 hours of salt spray testing per ASTM B117.
Surface Hardness
Achieves surface hardness of 70+ HRC.
Complete Coverage
Provides 100% part coverage.
Compound Zone
Produces a thick compound zone, or white layer, up to 0.0015″.
Oxide Layer, White Layer, and Diffusion Zone
The Plasox® process creates a multi-layer surface structure designed to improve corrosion resistance, wear performance, hardness, and friction characteristics while maintaining the dimensional integrity of the component.
Typical Plasox® Applications
- Tool holders
- Milling cutters
- Threading tools
- Drills
- Internal pump components
- Die casting components and permanent molds
- Steel-on-steel sliding and guiding applications
- Components requiring resistance to aluminum adhesion
- Gun components
- Specialty tools
Environmentally Friendly
The Plasox® protective coating method is environmentally friendly compared with many hot-dip coating and plating processes. It adds virtually no dimensional change, is extremely durable, and complements an already improved plasma ion nitrided surface.
