CVD-5B™ Metal Hardening

Email A Colleague

Trimteck is at the forefront of applying innovations in material science to extend the life of process control equipment. First used in the aerospace industry, CVD-5B is a chemical vapor diffusion process wherein a hard wear-resistant metal mesh is fused into the surface of a wide variety of ferrous and non-ferrous materials. Trimteck has harnessed and perfected this advanced hardening technology to – in some cases – effectively extend the life of our valves 10-fold.

Industrial customers have increasingly demanded that process control equipment also be wear-resistant and capable of sustaining higher temperatures, and CVD-5B was developed as a cost-effective alternative for addressing these process control issues. Unlike coatings and traditional hard facings that harden only the surface of the substrate material, during the CVD-5B hardening process, superheated boron atoms are diffused fairly deep into a host surface to form a metal boride layer that permeates evenly up to .015’’.
