В статье приведены основные проблемы износа и срока эксплуатации шиберных задвижек для магистрального трубопроводного транспорта нефтяной и газовой промышленности. Одним из возможных способов решения этих проблем является нанесение тонкого слоя износостойких и коррозионностойких покрытий. В связи с постоянно растущей стоимостью материалов, а также возросшими требованиями к материалам в последнее время все большее значение придается методам нанесения покрытий. Среди газотермических методов нанесения покрытий технология высокоскоростного кислородно-топливного напыления (HVOF) является новой и быстро развивающейся технологией, которая позволяет получать покрытия высокой плотности с пористостью менее 1%, обладающие повышенной твердостью и адгезией, а также  улучшенными свойствами эрозии, коррозии и износостойкости.   В этой обзорной статье проведен сравнительный обзор характеристик карбидных покрытий, полученных с использованием различных технологий напыления.

The article presents the main problems of wear and service life of slide gate valves for trunk pipeline transport of oil and gas industry. One of the possible ways to solve these problems is the application of a thin layer of wear-resistant and corrosion-resistant coatings. Due to the ever-increasing cost of materials, as well as the increased requirements for materials, coating methods have recently become increasingly important. Among the gas-thermal coating methods, the High Velocity Oxygen-Fuel Spray (HVOF) technology is a new and rapidly developing technology that produces high density coatings with porosity less than 1%, with improved hardness and adhesion as well as improved erosion, corrosion and wear resistance properties. This overview article provides a comparative review of the characteristics of carbide coatings produced using different spraying technologies.
