【 摘 要 】

The paper reports on coating of silumin samples with Al-Y2O3 by electric explosive alloying. When testing the micro-hardness, two appropriate processing modes of samples were revealed; the porosity of their surface profile was examined using atomic-force microscopy. A multi-layer structure was disclosed by metallographic microscopy, the thickness of each layer in the coating was determined as well. The mechanism of this structure formation was suggested.
