Ablation of a WC-Co alloy under exposure to high-power nanosecond ultraviolet laser pulses on purpose to modify the surface before application of diamond coating The surface of a WC-Co hard alloy was modified by scanning radiation from focused beams of a nanosecond ultraviolet (UV) laser. After exposure, chemical etching was carried out using the Murakami and Caro method and subsequent magnetron sputtering of a tungsten layer 600 nm thick. The optimal mode of preliminary laser heat treatment of the WC-9% Co alloy for the purpose of the upcoming application of diamond coating has been determined. This is We=1-2 J/cm2. Keywords: laser heat treatment, carbide (WC-Co), tungsten carbide, surface modification, diamond coating (DC).
