The influence of target temperature and dose on metallic strengthening for titanium implantation into steel - Zhang, T.; Ji, C.; Shen, J.; Chen, J.; Lin, W.; Sun, G.; Gao, Y. (Elsevier)
The formation of intermetallic compounds on titanium implantation into H13 steel at different target temperature (-196, 150 and 400 ^oC) is studied. The steel strengthening mechanism of titanium implantation with different doses and target temperatures was discussed. The titanium ions are implanted in the energy range from 100 to 300 keV and dose range from 1 x 10^1^7 to 5.5 x 10^1^7 cm^-^2.The observations of phase change, microstructure and intermetallic compounds were carried out by high voltage (1 MV) electron microscopy and X-ray diffraction analysis. The hardness of the implanted layer increases one to 2.5 times for low temperature (-196 and 150 ^oC) implantation, two to three times for moderate temperature (MT) (400 ^oC) implantation. The wear rate decreases two to 2.6 times for low temperature implantation and ten times for MT implantation. The influence of target temperature and dose on metallic strengthening is discussed.
