Kurdyumov of the National Academy of Sciences of Ukraine popup.description2 The stability of the powders of the investigated cobalt alloys in the gaseous hydrogen environment was investigated using the following method. At the first stage, the studied materials were kept at a hydrogen pressure of 0.23 MPa for 20 hours at room temperature. After the specified exposure time, the hydrogen pressure in the chamber was increased to 2.0 MPa. At the second stage, the tested powders were heated to a temperature of 630 ± 10 °C with subsequent cooling to room temperature. With the indicated heating, the hydrogen pressure in the chamber varied from 2.0 to 3.1 MPa. At the third stage, after the indicated heating, at a hydrogen pressure in the chamber of 2.0 MPa and at room temperature, the investigated powders were additionally aged for 140 hours. It was established that during the specified treatment there was no interaction between the investigated powders and gaseous hydrogen.  Product Description popup.authors Boshko Oleg Zagorulko Iryna popup.nrat_date 2023-12-25 Close
