What is CVD?
Hardide coatings are made through a proprietary low-temperature CVD process that deposits a nanostructured composite layer of tungsten carbide/tungsten metal matrix atom-by-atom. The result is a hard, crack-resistant, non-porous surface that is chemically bonded to the substrate.
Unlike traditional coatings that are sprayed or plated on, this vapour-phase deposition happens uniformly across every exposed surface. Whether the component has internal channels, fine threads or blind holes, the coating forms consistently and evenly even in non-line-of-sight areas.

Uniform coating on complex geometries
CVD coats internal surfaces, deep recesses and intricate shapes with 100% coverage removing the need for masking or complicated workarounds.
Outstanding durability
Hardide CVD coatings resist wear, erosion, impact and fatigue to outperform traditional coatings like Hard Chrome, HVOF and PVD by up to 24 times in comparative ASTM standard tests.
Environmentally safe
Hardide CVD coatings are REACH-compliant and free from hexavalent chromium and cobalt, making them a responsible alternative to outdated, toxic surface treatments.
No porosity, no shortcuts
The coatings are completely pore-free, providing a continuous and impenetrable barrier against corrosive chemicals, gases and liquids.
