Information × Registration Number 0122U002141, ( 0225U000171  ) R & D request Title Scientific and methodological principles of obtaining surface nanostructures on pearlitic steels for operation in corrosive and hydrogenating environments and development of a method for their diagnostics Head Zvirko Olha I., д.т.н. Registration Date 23-03-2022 Organization Physico-Mechanical Institute named after GV Karpenko of the National Academy of Sciences of Ukraine popup.description1 The aim of the work is to establish the basic structural parameters of formation of nanocrystalline structures (NCS) on pearlite steels by surface mechanical-pulse treatment (MPT) with alloying from technological environment, to investigate the influence of surface NCS on hydrogen permeability, wear resistance, corrosion resistance, resistance to fatigue and corrosion fatigue of steels, as well as to develop a method for diagnosing surface NCS using distribution of surface acoustic wave propagation velocity. popup.nrat_date 2024-12-09 Close
