Název v původním jazyce

Highly Oriented Zirconium Nitride and Oxynitride Coatings Deposited via High-Power Impulse Magnetron Sputtering: Crystal-Facet-Driven Corrosion Behavior in Domestic Wastewater

Popis výsledku v původním jazyce

Herein, highly crystalline ZrxNy and ZrxNyOz coatings are achieved by the deposition via high-power impulse magnetron sputtering. Various N-2 and N-2/O-2 gas mixtures with argon are investigated. The chemical composition and, as a result, mechanical properties of the deposited layer can be tailored along with morphological and crystallographic structural changes. The corrosion resistance behavior is studied by potentiodynamic measurements and electrochemical impedance spectroscopy in a sample of synthetic wastewater designed to imitate real-life domestic wastewater. The corrosion current density of the ZrxNyOz coating is in the range of 33-70 mu A cm(-2), whereas for the zirconium nitride layers, values below 1.0 mu A cm(-2) are achieved. The highest corrosion resistance of 64 nm year(-1) is observed for the ZrxNy coating deposited with 1.00% N-2 content in the gas mixture with a corrosion potential of -0.41 V Ag/AgCl.
