Formation of patina on a copper surface in polyacrylate gels with gold nanoparticles

摘要

The experimental research demonstrates the effective use of patination of the copper and copper alloys in containing gold nanoparticles in order to increase their protective properties. The copper samples were examined by cyclic voltammetry method, optical microscopy, and X-ray analysis. It has been shown that patinas obtained in the polymer gel solution have a better corrosion resistance in comparison with the patinas obtained with chemical methods.
