EFFECT OF CARBON IONS EMITTED FROM PLASMA FOCUS ON TITANIUM SURFACE

ABSTRACT: The energetic carbon ion beams originated from plasma column produced in Mather-type dense plasma focus (2.3kJ) is used for carburizing titanium substrate at room temperature, by increasing the carbon ion dose exposure. The titanium (Ti) samples are exposed at fix axial and angular position from the hollow copper anode tip. Surface properties of treated samples as a function of ion dose are studied for crystallinity, surface morphology and Micro-hardness using X-ray diffraction, scanning electron microscope, atomic force microscope and Microhardness tester. XRD results confirm the evolution of titanium carbide phases depending upon the substrate exposure to the carbon ion dose and angular position while smooth surface morphology is observed from SEM and AFM results while micro-hardness results of exposed samples showed significant improvement
