Abstract Scope Tribological applications for thin films necessitate high hardness, toughness, and good adhesion to the substrate material. While high hardness and toughness been relatively easy to achieve within a material system, obtaining adhesion along with the first two has historically presented great difficulties, leading to removal of the film. Recently, our discovery of Q-carbon created an alternative route for obtaining the required adhesion along with high hardness and toughness. In this work we present the formation of Q-carbon and diamond on tool steel and tungsten carbide substrates via ArF pulsed laser annealing. The wear rates of these films are compared to state-of-the-art CVD diamond films, and further complemented with Raman spectroscopy, high-resolution SEM/HRTEM imaging, electron energy-loss spectroscopy (EELS), and electron backscatter diffraction (EBSD). This technique shows great potential for high-speed machining, applications in oil and gas exploration, such as deep-sea drilling, and can be further adopted for usage in diamond electronics.
