Abstract / Full Text

The structural-phase state of a 30KhGSA steel cladded with a high-hardness heat-resistant R18-type steel alloyed with aluminum and nitrogen is studied by the x-ray diffraction method in the state after plasma cladding in a nitrogen atmosphere and high-temperature tempering. It has been established that the base phases in the cladded layer are α-Fe solid solution and carbonitrides based on iron, tungsten, chromium, molybdenum, and aluminum (Fe6W6NС and AlN). High-temperature processing (tempering) of the cladded layer leads to an increase in the crystal lattice parameter (from 2.866 to 2.890 Å) and sizes of coherent scattering region (from 25 to 100 nm) and a decrease in the internal elastic stresses (from 1000 to 600 MPa).
