The Electrical Properties And Microstructure Of An Ion Beam Mixed Metal-Polymer System
Ion beam mixing of the surface of polymers with metal films is done by ion implanting through a thin metal film. The metal layers are evaporated on the polymer substrate surface before ion implementation. A 50keV, nitrogen ion beam with a dose in the range of 10¹⁶ ions/cm² and a dose rate current …

The erosion of ductile metals by solid particle impact
Erosion is a wear process, in which surface damage is caused by the repeated application of high localised stresses. Erosion by solid particle impact is a problem of great practical significance which can result in component failures in, for example, turbines and energy conversion systems. This …

AUGER ELECTRON SPECTROSCOPY OF CRYOGENIC MATRIX ISOLATED METAL ATOMS AND DIRECT RECOIL SPECTROSCOPY (DRS), SIMS AND XPS STUDIES ON TITANIUM AND PIQ
… first time. Differences in extra-atomic relaxation between bulk metal and argon matrix isolated atoms resulted in shifts in the energy of LMM Auger electrons, $-3.1$ eV for potassium and $-8.7$ eV for titanium. The sum of the shift and the known difference between the energies of LMM Auger …
