Heat Resistance of Surface Layers Obtained by Electron Beam Surfacing with Cr–B Powder Mixtures

  • Published:
Russian Physics Journal Aims and scope

Results of investigation of the structure and properties of modified high-alloyed corrosion- and heat-resistant austenitic steel layers using the technology of non-vacuum electron-beam treatment are presented. Chromium and boron powders in various ratios have been used as modifying components. It has been established that Cr2B, (Fe,Cr)2B, and α- and γ-Fe phases are observed in the structure of the hardened layer, which directly affect the alloy properties. Tests carried out to assess heat and wear resistance showed that modification with chromium and boron makes it possible to increase the wear resistance by a factor of 4.3 and the heat resistance by a factor of 11.2 compared to the base metal.
