CVD-5B Metal Hardening

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 to harden rocket nozzles on the space shuttle, 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. We have altered and adapted the technology to make our control valves and parts last longer.

There are many metal hardening technologies on the market today, such as thermal sprays, stellite, and hard chrome facings. However, users are increasingly demanding that their 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 host material, during the CVD-5B process, superheated boron atoms are diffused deep into a host surface to form a metal boride layer that permeates evenly up to .015’’. Trimteck has harnessed and perfected this advanced technology to, in many cases, effectively extend the life of our control valves more than ten-fold.
