China / South Korea / United States PST® provided by Tribotec Europe – Germany (Göppingen) PST® provided by Tribotec Europe – Germany (Göppingen) Global PST® Network PST® surface treatment technology was developed by Philos Co., Ltd. Tribotec is the partner responsible for PST® in Europe. Industries We Serve What is PST®? PST® (Philos Surface Treatment Technology) is a patented diffusion-based metal surface treatment. Titanium (Ti) and nitrogen (N) are diffused into the material of tool steels, forming a deep, homogeneous diffusion zone with exceptional hardness and durability. Unlike conventional nitriding or PVD coatings, PST® is not an applied layer but diffusion zone, with the same thermal expansion coefficient as the matrix material making it highly resistant to thermal cycling and mechanical stress. Why Choose PST® by TriboTec? Maximize tool performance, durability, and reliability with our exclusive PST® surface treatment technology. Tool Life Extension PST® significantly increases the lifespan of molds and dies, reducing maintenance and replacement costs. Depending on the application, tool life can be extended up to 10 times compared to conventional treatments. High Surface Hardness The PST® diffusion process achieves surface hardness up to HRC 75 while maintaining core toughness. This ensures tools remain strong yet wear-resistant under extreme conditions. Wear & Corrosion Resistance PST® surfaces are highly resistant to wear, erosion, corrosion, and heat checking. This guarantees consistent quality and reliability of the products of our customers especially for high-volume industrial productions. Durable Diffusion Zone Unlike coatings or nitriding PST® forms a diffusion zone without geometric changes. There is no risk of delamination or brittle layers, providing maximum durability and long-term performance. Complex Geometry Friendly PST® can treat intricate shapes and highly polished surfaces without altering their geometry or finish.

In just a few clear steps, we collaborate closely with you – from analyzing your tools to releasing the treated components – ensuring a smooth process, precise results, and minimal downtime. Surface Cleaning & Activation All components are thoroughly cleaned and surface-activated to remove contaminants. This step is essential to enable uniform and effective diffusion during the PST® treatment. PST® Diffusion Treatment In a controlled low-temperature process (approx. 450–650°C), titanium and nitrogen diffuse into the tool steel surface. This creates a deep, integrated diffusion zone with high hardness and exceptional resistance to wear, heat and fatigue.
