   <abstract xml:lang="ru">
    <p>В статье представлены результаты анализа закономерностей износа фокусирующей трубки сопла гидроабразивной установки при введении поверхностно-активных веществ (ПАВ). Описаны примененные методы, подходы и особенности организации экспериментальных исследований. Проанализирован процесс формирования волнообразного рельефа внутри канала фокусирующей трубки в зависимости от продолжительности работы сопла. Приведены данные об измерении областей эрозии канала трубки на начальных, промежуточных и заключительных участках. Выявлено, каким образом введение поверхностно-активных веществ (ПАВ) в поток жидкости воздействует на степень износа, форму и траекторию разрушения стенок канала фокусирующей трубки. Представлены результаты оценки интенсивности уноса материала канала по временному фактору и коэффициенту потери массы. Сформулированы рекомендации по улучшению конструкции фокусирующей трубки для эффективного использования ПАВ в процессах гидроабразивной резки.</p>

    <p>The paper presents the analysis results of wear features of the nozzle focusing tube of a hydroabrasive installation when introducing surfactants. The applied methods, approaches and features of arranging experimental research are described. The wave-like relief formation inside the channel of the focusing tube is analyzed, depending on the duration of the nozzle operation. Data on the measurement of the erosion areas of the tube channel in the initial, intermediate and final sections are presented. It is found out how the introduction of surfactants into the liquid flow affects the degree of wear, shape and trajectory of destruction of the focusing tube channel walls. The results of estimating the intensity of channel material entrainment by the time factor and the mass loss coefficient are presented. Recommendations are given to improve the design of the focusing tube for the effective use of surfactants in hydroabrasive cutting.</p>
