Carbide Rods and Preforms

Achieving high-quality diamond coatings on tungsten carbide tools is a complex process. The performance of the coating, characterized by its uniformity, density, finish, and adhesion, hinges on the choice of substrate material. Many tungsten carbide grades are unsuitable for CVD diamond deposition, resulting in coating defects like peeling, non-uniformity, and roughness, or even a complete lack of diamond growth. Through extensive testing and validation spanning over a decade, Toolind Inc. has developed a range of superior tungsten carbide substrates designed specifically for successful CVD diamond coating. These materials are now readily available.
