UltraGlow® Ion Nitriding
UltraGlow® Ion (Pulse Plasma) Nitriding is a case-hardening treatment which uses glow discharge technology to introduce nitrogen ions to the surface of a metal for diffusion into the part. This process is carried out in a vacuum vessel where a high-voltage electrical charge forms plasma, causing nitrogen ions to accelerate and impinge on the metal. When the nitrogen ions bombard the part they heat up the metal, clean the surface, and absorb nitrogen into the surface.
Benefits:
- Extends part/tool life
- Selective hardening process
- Reusable masking (versus coatings or other surface treatments)
- Adds performance, fatigue strength and endurance
- Enhances surface lubricity
- Reduces erosion
- Increases material flow in molds and dies
- Improves corrosion resistance
- No post-process machining
- Improves wear resistance
- Zero to minimal growth/distortion
- Precise and versatile
- Environmentally friendly process (i.e. free of toxic sales, ammonia and any other toxic gases)
- Phase controllable compound zone (or white layer)
UltraGlow® Gas Nitriding
UltraGlow® Gas Nitriding is a case-hardening process whereby nitrogen is introduced into the surface of a solid ferrous alloy by holding the metal at a suitable temperature in contact with a nitrogenous gas, usually ammonia.
Benefits:
- Extends part/tool life
- Adds performance, fatigue strength and endurance
- Enhances surface lubricity
- Reduces erosion
- Increases material flow in molds and dies
- Improves corrosion resistance
- No post-process machining
- Improves wear resistance
- Zero to minimal growth/distortion
- Precise and versatile
- Phase controllable compound zone (or white layer)
Ferritic Nitrocarburizing
Ferritic Nitrocarburizing is a thermochemical treatment which involves the diffusional addition of both nitrogen and carbon to the surface of ferrous materials usually at temperatures not exceeding 1100°F. The primary objective of such processing is to improve the anti-scuffing characteristics of ferrous engineering components by producing a white layer (compound zone) at the surface of the part, which has excellent tribological properties.
Oxidation Treatment
Advanced Heat Treat’s Oxidation Treatment can further improve the corrosion resistance properties attained by the nitriding cycle. This is a passivation process in which oxygen bonds with ferrous alloys at a low processing temperature. This process will also cause the part to change to a blackish or steel-bluish color, which is sometimes referred to as a “black oxide” process.
