Abstract

This paper aims at the characterization of plasma microjets generated by open microhollow cathodes to ionize gases such as air, N₂, He and O₂. The electrical and optical parameters were raised. Through the optical emission spectroscopy, gas temperature (T_g) and the excitation temperature were estimated. T_g ranging from 2100K to 600K for a gas flow rate ranging from 0 to 400ml/min. From 150 to 400ml/min T_g remained close to 700K. As an application, the treatment of smooth surfaces of high density polyethylenes (HDPE) was performed with a view to improve the hydrophilic property of the surface.
