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...

| description | 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 without the incorporation of carbon nanotubes (CNTs) on the Mg alloy surface. In contrast to NiCrAlY and NiCrAlY/nTiO2, the NiCrAlY/nTiO2-CNT nanocomposite coating displayed a higher bonding strength. The wear behaviour of the coatings was examined by the pin-on-disc test and the results revealed that the incorporation of CNTs into the nTiO2 coating considerably enhanced the tribological behaviour of Mg alloy due to the CNT’s bridging mechanism. |
