Описан метод обработки карбида вольфрама с использованием лазерной абляции наносекундной длительности импульсов. Представлены результаты анализа морфологии поверхности карбида вольфрама после воздействия коротких лазерных импульсов. Шероховатость обработанной поверхности исследована методом контактной профилометрии. Исследовано влияние параметров лазерного воздействия (частота следования импульсов, длительность импульсов) на геометрические параметры (глубина абляции и шероховатость) поверхности заготовок из карбида вольфрама. Установлено, что с увеличением плотности энергии, длительности импульса и повышением коэффициента перекрытия лазерных импульсов увеличивается шероховатость обработанной поверхности. Установлено, что тангенциальная стратегия лазерной обработки обеспечивает наилучшее качество поверхности.</p></abstract><trans-abstract xml:lang="en"><p>The laser ablation method has significant advantages in processing workpieces from hard materials, since it ensures the removal of material without wear of the forming tool and load on the workpiece. A method for processing tungsten carbide using laser ablation of nanosecond pulse duration is described. The results of the analysis of the tungsten carbide surface morphology after exposure to short laser pulses are presented. The roughness of the processed surface is studied using the contact profilometry method. The effect of laser exposure parameters (pulse repetition rate, pulse duration) on the geometric parameters (ablation depth and roughness) of the surface of tungsten carbide workpieces is studied. It is found that with an increase in energy density, pulse duration and an increase in the overlap coefficient of laser pulses, the roughness of the processed surface increases. The tangential laser processing strategy is shown to provide the best surface quality.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>импульсная лазерная абляция</kwd><kwd>наносекундный лазер</kwd><kwd>карбид вольфрама</kwd><kwd>производство микроинструментов</kwd><kwd>лазерная обработка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pulsed laser ablation</kwd><kwd>nanosecond laser</kwd><kwd>tungsten carbide</kwd><kwd>micro-tool manufacturing</kwd><kwd>laser processing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке программы „Приоритет 2030“.
