    Notes: Nitrogen implantation was observed to significantly improve the dry sliding properties of an ion beam mixed Fe50Ti50 surface alloy on AISI 304 stainless steel. Implantation to the fluence of 1.7×1017 N/cm2 at 50 keV increased the wear resistance but a decreased friction coefficient was obtained only after few hundred cycles at the beginning of the pin-on-disk test. When nitrogen was implanted to the fluence of 3×1017 N/cm2 an improved wear resistance and decreased friction were detected throughout the test of 1000 cycles. In addition, good sliding properties were also found at higher loads in the high fluence, nitrogen-implanted samples. These results differ from those obtained following a nitrogen implantation into Ti-implanted iron or iron-based alloys and are attributed to higher titanium and nitrogen concentrations.

    Microstructure of ion-bombarded Fe–Ti and Fe–Ti–C multilayered films (1986)

    Notes: Ion-beam-induced microstructure of the iron-rich end of the Fe–Ti and Fe–Ti–C systems was studied by using multilayered thin-film samples with a linearly varying composition of the metallic constituents. The ion bombardment was carried out using Xe++ ions at 600 keV. A mixing of iron and titanium in binary samples was complete after a bombardment with 8×1015 ions/cm2 whereas Fe–Ti–C samples were only partially mixed after the fluence of 1.8×1016 ions/cm2. Transmission electron microscope studies revealed that the microstructure of Fe–Ti samples was amorphous or amorphous and crystalline iron over a wide range of the compositions investigated. In the case of Fe–Ti–C, the microstructure consisted of crystalline iron and titanium together with a very little amorphous phase.
