Hardide Coatings

The Company

Hardide Coatings is the leading global innovator and provider of advanced tungsten carbide coatings that significantly increase the life of critical metal parts operating in abrasive, erosive, corrosive and chemically aggressive environments.

The company was formed in 2000 by a team of UK venture capitalists to develop and commercialise a patent for the Hardide CVD (chemical vapour deposition) coating process.

In 2003, Hardide Coatings’ headquarters and UK manufacturing facility was established in Bicester, Oxfordshire. From this location, we serve customers around the world including the UK, Europe, the Far East and Australia. In 2016, the company opened a coatings facility in Martinsville, Virginia, USA which processes parts for customers in North America.  Since the company was founded further patents have been registered and Hardide plc now has a strong IP portfolio which is under constant review.  The company continues to research and develop coating variants with additional features to add to the IP asset base.

Hardide plc has been listed on the London Stock Exchange’s Alternative Investment Market (AIM: HDD) since 2005.

The Technology

Hardide coatings is a family of nanostructured tungsten carbide based coatings that that are highly abrasion, erosion, corrosion and chemical resistant while also being tough, ductile and impact resistant.

Applied by low temperature chemical vapour deposition (CVD), they can coat internal surfaces and complex shapes and are ideal for tightly toleranced parts. They possess a unique combination of properties and features in one coating. This provides significant advantages over other hard facing coating technologies:

  • An environmentally compliant replacement for hard chrome
  • Extreme wear, abrasion & erosion resistance
  • Corrosion & chemical resistance
  • Toughness, ductility & impact resistance
  • Uniform and conformal coating
  • Low friction
  • Cobalt and binder-free
  • Pore-free, dense, homogeneous structure
  • Smooth and uniform ‘as coated’ finish
  • Reduced finishing time
  • Improved design opportunities
