The University of Southwestern Louisiana`s (USL) Acadiana Research Laboratory has been collaborating with several other Louisiana universities and industrial sponsors utilizing a National Electrostatics Corp. 5SDH-2 1.7 MV Tandem Pelletron accelerator system. Particle Induced X-ray Emission Spectroscopy (PIXE) and Rutherford Backscattering Spectrometry (RBS) have been combined with MeV ion implantation to investigate industrial applications of MeV ion analysis and modification techniques. Iron and titanium substrates have been implanted with singly and doubly charged ions of aluminum, silicon, nickel, zinc, gold, and chromium with energies 0.250 - 5.1 MeV to study the resulting effects on adhesion of engineering ceramic coatings on metals and the resulting effect of high temperature corrosion inhibiting properties of these coatings. Oxide formation on iron and titanium surfaces is being studied using RBS. The trace element analysis capability provided by PIXE will help determine trade routes used by prehistoric Indians and metal uptake by trees.
