title: Methods for Increasing the Operating Life of Shut-Off Valves of Thermal Power Plants
abstract: The influence of various coatings on the corrosion resistance of the valve stem of shut-off valves has been studied. To assess the quality of the obtained coatings, microhardness, corrosion resistance, deformation-strength and tribological characteristics were determined. Researches have shown that the most optimal way of anticorrosion protection for the shut-off valve stem is chromium-plating, which provides corrosion proofing, increases wear resistance and surface microhardness
