Abstract
In this work, a first ever application of Polymer Derived Ceramics coatings based on SiOC glasses, on Cu-based alloys (pure Cu and CuNi10Fe1.6Mn cupronickel) for marine applications was reported. Sol-gel method and dip-coating technique with further thermal treatment at 800 °C in Ar atmosphere were used to produce the coatings that were subjected to the corrosion resistance studies with salt spray testing in 3.2 % NaCl environment at 35 °C. Advanced characterization of microstructure (Optical and SEM microscopy) with elemental composition (EDS) as well as structure (X-Ray Diffraction, FTIR and Raman spectroscopy) of as-coated and corroded (bare and coated) specimens was performed. Conducted studies revealed the issue of cracks formation during pyrolysis step, as well as no improvement in pure Cu corrosion resistance by means of SiOC coating. However, despite cracks, a considerable enhancement of CuNi10Fe1.6Mn alloy corrosion resistance was observed due to the high chemical compatibility of SiOC coating and used cupronickel. It was possible to illustrate a phase distribution in cross-sectional analysis using the Raman confocal imaging, which revealed mostly Cu2O mixed with spinel-type (Cu,Fe,Mn,Ni)3O4 oxide and Mn oxides in corrosion products, as well as Mn oxides and NiO within the interdiffusion layer that chemically bonded ceramic coating enriched in strong, resistant Si-C bonds and free carbon phase, to the metallic substrate providing an effective barrier against aggressive Cl− environment.
