Plasma Nitriding for Wear, Hardness & Fatigue Life

Extend component life with precise, low-distortion surface hardening.

Plasma nitriding forms hard, wear-resistant nitride layers by diffusing nitrogen into the surface using a controlled glow-discharge plasma. Compared with gas or salt bath nitriding, plasma offers the lowest activation temperatures and most tunable process conditions, minimizing distortion while targeting the case depth and hardness profile your application requires.

Since 1992, Patt Technologies has run pulse plasma nitriding to improve the durability of our own filtration systems, we then brought that expertise to automotive, aerospace, and medical customers. 

Every batch is run with a process tailored to it: gas chemistry, pulse parameters, bias voltage, and temperature. This is done with the goal of delivering deep, uniform cases, with strong adhesion, and repeatable results for tight-tolerance parts.

What you can expect

• Custom processes for each alloy/part to meet demanding specs
   
• Uniform case formation with excellent adhesion and edge coverage
   
• Low-distortion treatment for thin-wall, high-precision components
   
• Improved wear resistance, surface hardness, and fatigue strength
   
• Compatibility with common engineering alloys (tool steels, stainless steels, Ni-base alloys, Ti, etc.)
  
   

Typical applications: valves and seats, dies and adapters, extrusion components, bearing races, shafts, surgical instruments, and high-precision wear parts.
