Abstract

On this  work  were  grown and characterized thin films of  zirconium oxide on seven different substrates: common glass, silicon  (100)  and  stainless  steel  AISI  304,  304LS,  316L,  321  y  2205.  The  coatings  were  deposited  by ultrasonic  spray pyrolysis  technique  and  the  effect  of  some  deposit  variables  was  analyzed.  Some  of  the  variables  were:  substrate temperature, the flow ratio of impact and drag, and deposition time. Deposited phases identification  was carried out by X- ray diffraction  scanning electron  microscopy and atomic  force microscopy. The phase  analysis of steel and coating  was performed  by  Rieltveld  refinement  and  surface  chemical  analysis  performed  by  X-ray  Photoelectron  Spectroscopy.  The results show homogeneous films, with high reproducibility in the tetragonal crystalline structure and shows stability over time. The coatings deposited on 316L steel showed a higher orientation in the plane (101), while the other substrates show mixed orientation.
