This technology presents nano-structured tungsten carbide particles, dispersed in a tungsten metal matrix, to make a coating that can be applied via low-temperature Chemical Vapour Deposition (CVD) technology. This coating can do what most traditional coatings cannot: coat both internal and external surfaces, non-line-of-site areas, combing exceptional wear and corrosion resistance with toughness and ductility. Used on critical parts of oil and gas tools, pumps, valves, and aircraft components, this coating would typically triple their service life, especially in abrasive, erosive, or corrosive conditions.
The technology owner seeks technical and/or R&D technical cooperation to develop applications for tungsten carbide CVD coatings.
This advanced coating is crystallised from gas media, atom-by-atom, enabling the coating of both internal and external surfaces and complex shape parts which are difficult or impossible to coat by most traditional coatings.
The following are properties that this technology carries:
The nanostructured tungsten carbide coating has been proven on critical parts of oil drilling tools, pumps, valves, aircraft components and other precision components, protecting them against mechanical and chemical degradation, and typically triples the parts’ service life.
Other potential applications of the coating are (but not limited to):
Advanced coatings are increasingly used across high-value manufacturing sectors, and help in making industrial equipment more competitive.
This coating enables producers of industrial equipment to make it more durable, reduce maintenance requirements and cut expensive downtime. The coating is able to replace hard chrome plating which is restricted by REACH regulations.
This coating technology has the following advantages:
