Abstract:
The hybrid system chemical vapor deposition (HYSYCVD) process is used in this work in order to synthesize zirconium nitride species (ZrNx) by means of the thermal decomposition of a solid precursor (potassium hexafluorozirconate, K2ZrF6) in a nitrogen N2 atmosphere. The synthesis of the zirconium nitrides is carried out in a deposition reactor designed and built at the University of Colima, Mexico. These nitrides ZrNx are deposited at the surface of low-carbon steels with the purpose to increase their surface mechanical properties. The zirconium nitrides are also microstructurally characterized by scanning electron microscopy, atomic force microscopy and by X ray diffraction, while the hardness is determined by Vickers microindentation test. The HYSYCVD process is an alternative process to common CVD processes due to the fact that it is possible to synthesize different transition metal nitrides utilizing solid-gas precursors at the same time.
