Titania-carbon nanotubes nanocomposite coating on Mg alloy: microstructural characterisation and mechanical properties

Titania-carbon nanotubes nanocomposite coating on Mg alloy: microstructural characterisation and mechanical properties

Atmospheric plasma spraying was carried out to deposit a bilayered NiCrAlY/nTiO2-CNT composite coating. Initially, NiCrAlY, as an under-layer with a thickness of around 100 µm, was deposited. Afterwards, nanostructured TiO2 (nTiO2), as an over-layer with a thickness of 135 μm, was deposited with and...
