Abstract
Ion implantation of aluminum and stainless steel alloys is a useful method for the improvements of their tribological properties and hardness. This paper presents a preliminary study of the influence of titanium implantation on the tribological properties and hardness of the commercial duralumin and stainless steel alloys. The friction, wear and hardness measurements have been carried out at energy 150 keV and different Ti ion doses up to 10 17 Ti +/cm 2. The obtained results exhibited a significant improvement in the friction coefficients, and wear rates in the commercial duralumin alloy at the higher dose. The hardness tests for the stainless steel alloy showed a clear improvement and a slight increase for the duralumin alloy at Ti ion dose 10 17 ions/cm 2. The depth distribution of titanium in the implanted stainless steel at the dose 10 17 ions/cm 2 has been measured by Rutherford backscattering and SIMS techniques.
