“…During operation in this temperature range, degradation of corrosion properties occurs for a long time [21,22]. In one of the previous works [23], it was found that the fraction of precipitates of the second phase (χ-phase) correlates with the energy density of the laser beam during selective laser melting. The ability to control the kinetics of second phase formation is one of the key factors for improving the corrosion resistance of alloys.…”

Austenitic steel 316L is a common corrosion-resistant structural material used in a variety of industries from food to nuclear. There is a well-known tendency of steel 316L to precipitate second phases in the temperature range of 500 ... 800 ° С. During operation in this temperature range, degradation of corrosion properties occurs for a long time. Materials and parts obtained by modern methods of additive technologies are of great interest, since this method of alloys processing affects the thermodynamic equilibrium of the system and the kinetics of the release of second phases in aging alloys. The ability to control the kinetics of second phase formation is one of the key factors for improving the corrosion resistance of alloys. In this work, the effect of the method of steel 316L manufacturing (traditional and selective laser melting) on corrosion resistance at a temperature of 750 ° C for 100 hours in a KCl-NaCl environment was estimated. Corrosion tests were carried out, as a result of which it was found that a sample of 316L steel obtained by the method of selective laser melting has the lowest corrosion rate..
