Abstract

This study investigates the effect of surfacing with Sv-10Х17Т welding wire on the tribological properties of steel samples. The research is motivated by the need to extend the service life of components operating under frictional loads while reducing the maintenance and repair costs. The focus is on a key element of the pipeline shut-off valves, the wedge of a wedge gate valve, which experiences high contact stresses and severe wear during operation. Laboratory tests were conducted under various friction conditions, involving dry friction, water-based media, and oil-based media. Parameters, such as the coefficient and moment of friction, contact temperature, mass loss, wear depth, surface microhardness (both before and after testing), and surface roughness (Ra), were systematically measured. Experiments with steel samples surfaced using Sv-10Х17Т welding wire were designed to replicate actual valve working conditions. The results showed that Sv-10Х17Т surfacing significantly increased wear resistance, reduced friction, and enhanced surface microhardness, particularly under prolonged dry friction. The microstructural analysis confirmed the formation of a hardened riveted surface layer with deformation strengthening and partial thermal treatment. These findings indicate that Sv-10Х17Т surfacing not only restores, but also improves the performance of the steel components, offering an effective method to extend the operational life. The outcomes of this research have practical value for mechanical engineering, as well as the repair and maintenance of pipeline equipment, turbines, gearboxes, bearings, valves, and other critical components.
