## Description

- description: "We have developed the titanium oxynitride (TiON) layer which exhibits
    antibacterial activity against\r\nEscherichia coli without sunlight irradiation.
    This TiON layer with the segmented structure was formed on a pre-oxidized Ti substrate
    by the electron beam physical vapor deposition method while spraying the substrate
    and Ti target with N2-0.1%O2 gas. An XRD pattern of the surface of the segmented
    layer revealed that the layer has a rock salt structure, which is preferentially
    deposited in a [111] direction to the substrate surface. TEM observation of the
    TiON layer showed that the columnar segments have a feather-like structure. The
    width of the segments near the surface was 100–500nm, and their outermost surfaces
    were covered with nanometer-sized\r\nspines of 10–50nm width. The TiON layer contained
    about 20 at% nitrogen as determined by XPS, and the surface was slightly negatively
    charged with a zeta potential of ¹0.9mV at pH 7.2. The maximum average pressure
    in the elastic deformation region for the layer was over 100 MPa, which was much
    higher than the average occlusal pressure (<10 MPa). It is concluded that the
    segmental structure of the film facilitates the elastic deformation without distorting
    of the unique surface structure in response to external stress."
