SYNTHESIS OF TiN FILM BY ION BEAM ENHANCED DEPOSITION AND ITS PROPERTIES
TiN薄膜的合成及其性能研究

The TiN film was synthesized by alternate deposition of Ti and nitro-gen ion bombardment under 40 keV at room temperature. The component depthprofiles and the structure of the film have been investigated by means of RBS,AES, TEM, XPS and X-ray diffraction. The results showed that the TiN films syn-thesized by ion beam enhanced deposition (IBED) are mainly composed of TiNcrystallites, sized about 30-40 nm, with random orientation. The oxygen contaminationin TiN film prepared by IBED is less than that of the deposited film without nitrogenion bombardment. It was confirmed that there is a significant intermixed layer, about40nm thick, at the interfaces. The films formed by IBED exhibit superior hardnessand improvement over the wear resistance and frictiton properties.
