Abstract

Microstructure as well as micro-mechanical and tribological properties of hard surface layers formed on Timetal 834 alloy during its nitridation or oxynitridation under glow discharge were investigated. The tests show that both layers exhibited higher microhardness and Young’s modulus as well as much better wear resistance than the untreated alloy.

The microstructure investigations, performed by light microscopy and analytical transmission electron microscopy methods, show that improved micro-mechanical and tribological properties of surface-treated alloy are related to the presence of a multiphase micro/nanostructure containing several sublayers with different morphologies and composition.

Keywords: Titanium alloys; Analytical TEM; Microstructure; Surface layers; Wear resistance
