Abstract
The work studies X8 CrNiSiMg 17-8-6 steel powder, a Russian alternative for AISI 304 steel, cladded by ytterbium fiber laser on two types of substrates: heat-resistant steel and low-carbon steel. The results demonstrate the effect of laser radiation power on the macrostructure of single cladded beads and their fusion with the substrate. The selected regimes allow forming solid cladded layers. The paper also studies the microstructure of metallographic sections of cladded specimens, the phase composition of cladded layers and initial powder. The deliverables include the data on wear resistance, resistance to intercrystalline corrosion and strength of cladded layer fusion with the substrate.
