Investigation of mechanical characteristics of composite surface layers using materials with thermoelastic properties

We developed the formation technology of the steel–layer with elastic phase transformations–ceramic wear-resistant layer composition by means of high-velocity oxygen fuel spraying (HVOF) in the protective medium of mechanically activated powders TiNiCu and cBN-Co-Mo.

Description
Summary:We developed the formation technology of the steel–layer with elastic phase transformations–ceramic wear-resistant layer composition by means of high-velocity oxygen fuel spraying (HVOF) in the protective medium of mechanically activated powders TiNiCu and cBN-Co-Mo. We also determined optimal processing parameters. We revealed regularities in the formation of the nanoscale state of the composition on the basis of complex X-ray diffraction and electron-microscopic studies. We carried out tests of steel 1045 with surface-modified layers TiNiCu + cBN-Co-Mo on friction wear, which showed an increase in wear resistance.
