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.
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.

Why Choose PST® by TriboTec?

Maximize tool performance, durability, and reliability with our exclusive PST® surface treatment technology.
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. This makes it ideal for HPDC molds and precision tooling.
