1 May 2021 to 30 Apr 2023
The REALM project will develop a new, sustainable manufacturing technology to produce hard-facings for downhole drilling tools. The proprietary technology uses a novel metal additive manufacturing process based on Directed Energy Deposition (DED) to form highly wear resistant hard-facing coatings in-situ, using elemental powders. The super-hard coating is...
1 Dec 2020 to 31 Mar 2023
To create a new carbide composition for metal additive manufacturing processes and technologies for linear edge saw blades.
1 Feb 2020 to 31 Jul 2021
"C4 Carbides innovative saw blade development program will use Selective Laser Melting (SLM), a metal Additive Manufacturing (AM) technology, to fuse super-abrasive powder to form tooling grade hard materials into net shape 'sharp' cutting teeth, eliminating the needs of post process grinding. UK patents for this concept have been filed. Compared to conve...
1 Apr 2018 to 31 Mar 2020
"We will use innovative additive manufacturing to radically update the process for forming hard teeth on saw blades. The most commonly used tooth tip material is tungsten carbide. In a typical tipped blade less than 1% of the high value wear material is used. The rest is machined off during the manufacturing process or left on the base and discarded when ...

C4 Carbides currently manufactures linear edge tunsten carbide and diamond coated strip for cutting and drilling products. Tungsten is high on the list of ‘at risk’ minerals so there is an incentive to substitute tungsten carbide by other minerals. Diamond is a good alternative in many applications but is not suitable for ferrous materials. Cubic Boron Ni...
1 Nov 2013 to 28 Feb 2014
The project concerns new coatings for the cutting tools used in many advanced and high-value manufacturing applications. It will explore systematically the possibility of simultaneously (i) substituting diamond grit for tungsten carbide using a novel coating technology and (ii) retooling worn out tools and cutting blades rather than disposing of them. In ...
1 Jan 2013 to 30 Sep 2014
C4 Carbides currently manufactures and sells three product ranges: synthetic diamond-coated & tungsten carbide-coated power drill accessories and tungsten carbide saw blades. These are sold to some of the world’s leading brands including Bosch, Black and Decker, AEG and Hitachi. We have developed a novel method for diamond coating. This project aims to co...
1 Sep 2011 to 31 Jan 2014
To develop a capability in new diamond-to-steel bonding processes to enable expansion of linear edge technology into new products and markets.
