Abstract
We developed formation technology of composition "steel - material with shape memory effect - high-temperature ceramic wear layer" by means of high-velocity oxygen-fuel spraying in the protective environment of mechanically activated powders TiNiTa and cBN-Co-NiAl-Y. We determined optimal processing parameters. We revealed regularities in the formation of nanosized state composition on the basis of the complex X-ray diffraction and electron microscopy studies. We carried out tests om steel 1045 with a surface-modified layer TiNiTa + cBN-Co-NiAl-Y in high-cycle fatigue, which confirmed the increase in endurance limit.
