Active screen plasma nitriding treatment

●Practical use of two-step irradiation technology in industrial processes!
Step 1: Glow discharge between the furnace wall and screen
Step 2: The material temperature rise using heat radiation from the screen. Surface modification treatment by reactive action species passing through the screen.

This is noteworthy! Advantages of not using radiated plasma directly on workpieces:
　1) No damage from discharge on the workpiece surface
　2) Homogeneous film formation

●Proven achievement (the example of application for the stainless steel material, Silicolly)
Hardness level of base material: 56HRC (615HV or equivalent)
Surface layer after nitriding treatment: 1000HV

●Leave small-lot processing to HATTA!
- Responses to multi-product and small-lot requests anytime, 24-hours a day
- The detailed production system using “service tables”

●Pure nitriding and soft nitriding also available!
Hatta's technology makes full use of energy from nitrogen ion
- Treatment at low temperatures and minimal distortion in comparison to other methods
- Post-processing is unnecessary with simultaneous nitriding treatment
- Improved wear resistance and corrosion resistance
- Popular applications
　Components of automobiles, machine tools, precision equipment, etc.

●Clean heat treatment: Vacuum heat treatment
Technologies applied early by Hatta Kogyo.
Treatment available for vacuum brazing, diffusion bonding, etc. in addition to vacuum hardening and vacuum precipitation hardening.
- No oxidation or decarburization due to heating from the inside of the furnace in a vacuum state. Heat treatment methods with excellent photoluminescence
- Little carbon dioxide is emitted during heating and cooling. Amount of gas used is small for the ambient air.
