Abstract: 

IN THE PRESENT STUDY THE EFFECT OF NITROGEN BOMBARDMENT ON THE STRUCTURE OF TITANIUM SURFACE AND CORROSION RESISTANCE HAVE BEEN INVESTIGATED. IN THIS EXPERIMENT 30 KEV NITROGEN ION BEAM OF 5´1017 TO 1´1018 IONS/CM2 FLUENCE WAS USED. CRYSTALLINE STRUCTURE AND CRYSTALLINE SIZE OF THE DIFFERENT SAMPLES WAS STUDIED BY X-RAY DIFFRACTION ANALYSIS. THE ROUGHNESS VARIATIONS BEFORE AND AFTER BOMBARDMENT WERE OBSERVED BY ATOMIC FORCE MICROSCOPY. THE CORROSION TEST WAS USED TO COMPARE THE CORROSION RESISTANCE OF TITANIUM BEFORE AND AFTER BOMBARDMENT. THE SURFACE MORPHOLOGY OF THE SAMPLES WAS INVESTIGATED BY SCANNING ELECTRON MICROSCOPY THE RESULTS SHOWED THAT CRYSTALLINE SIZE CHANGES BECAUSE OF ION BOMBARDMENT HAS A SUBSTANTIAL EFFECT ON THE IMPROVEMENT OF TITANIUM RESISTANCE AGAINST CORROSION.
