Processing of an ultrafine-grained titanium by high-pressure torsion: An evaluation of the wear properties with and without a TiN coating
A commercial purity (CP) Grade 2 Ti was processed by high-pressure torsion (HPT) using an imposed pressure of 3.0GPa at room temperature. The HPT processing reduced the grain size from ∼8.6μm in the as-received state to ultra-fine grains (UFG) of ∼130nm after HPT. Tensile testing showed the HPT-proc...

| description | A commercial purity (CP) Grade 2 Ti was processed by high-pressure torsion (HPT) using an imposed pressure of 3.0GPa at room temperature. The HPT processing reduced the grain size from ∼8.6μm in the as-received state to ultra-fine grains (UFG) of ∼130nm after HPT. Tensile testing showed the HPT-processed Ti exhibited a good combination of high ultimate tensile strength (∼940MPa) and a reasonable elongation to failure (∼23%). Physical vapour deposition was used to deposit TiN coatings, with a thickness of 2.5μm, on Ti samples both with and without HPT processing. Scratch tests showed the TiN coating on UFG Ti had a critical failure load of ∼22.5N whereas the load was only ∼12.7N for the coarse-grained Ti. The difference is explained using a simple composite hardness model. Wear tests demonstrated an improved wear resistance of TiN coating when using UFG Ti as the substrate. The results suggest that CP Ti processed by HPT and subsequently coated with TiN provides a potentially important material for use in bio-implants.
► Grade 2 pure Ti was processed using high-pressure torsion method, to grain size of 130nm. ► A TiN coating was deposited on UFG Ti, to improve the wear resistance. ► Substrates play an important role on scratch and wear performances of TiN coating. ► UFG Ti coated with TiN provides a potentially material for bio-implants. |
