Microstructure and Properties of hard Layers Formed by Duplex Surface Treatment Containing Nickel and Phosphorus on a Titanium-Base Alloy

摘要

Microstructure and chemical composition of the hard Ni-P-Ti layer formed on the Ti-6Al-4V alloy after duplex surface treatment were investigated by light microscopy. X-ray diffraction, scanning electron microscopy and analytical/high resolution transmission electron microscopy. The investigation revealed a clear correlation between the microanostructure of the multiphase layer with its micro-mechanical and tribological properties.
