The phase, morphology and surface characterization of Ti–Mo alloy films prepared by magnetron sputtering

Abstract

Magnetron sputtering is a physical vapor deposition process which allows the formation of metastable materials because of the particle bombardment process.

Electrochemical and in vitro biological behaviors of a Ti-Mo-Fe alloy specifically designed for stent applications

“…The Mo3d spectra of TMF MP and TMF EP ( Fig. 2 (j-k)) were fitted by components associated with metallic Mo (located at 227.0 eV-227.1 eV and at 229.8–230.4 eV) [ 38 , 54 ], MoO 2 (located at 228.6 eV-229.1 eV and at 231.5–232.3 eV) [ 38 , 55 ] and MoO 3 (located at 233.1 eV-234.1 eV and at 235.0–236.2 eV) [38] . The concentration of metallic Mo in TMF MP and TMF EP was 37.3 at.% and 33.5 at.%, respectively.…”

Microstructure and Mechanical Properties of Co-Deposited Ti-Ni Films Prepared by Magnetron Sputtering

“…It is also consistent with the finding that the addition of alloying elements (e.g., Cr, Nb, Mo, etc.) promotes the stabilization of the β-phase in the Ti-based alloy films [26][27][28]. According to a previous study of Ti-Cr films, with the addition of ~10 at.…”

“…Note that the increasing Cr content has little change in the modulus of Ti-Cr films, retaining the values at ~95 GPa. Liu et al [28] revealed the phase formation and morphology evolution of sputtered Ti-Mo films under different substrate temperatures. The Ti-15Mo film could retain the β phase at 50~100 °C, while the Ti-30Mo film could maintain the β phase at higher temperatures up to 300 °C.…”

Kinetics of the binodal decomposition of the metastable Ni0.5Ru0.5 solid solution

“…A large number of metastable metal alloys are known which can mainly be divided into groups such as supersaturated solid solutions, crystalline intermetallic compounds, quasicrystalline phases and metallic glasses. The main methods for the synthesis of metastable alloys are melt or solid quench (conventional casting, 1 rapid solidification, 2,3 laser pulse 4 ), condensation (vapor–gas, 5 sputtering, 6,7 electrodeposition, 8 chemical 9,10 ), irradiation (particle bombardment, 11,12 ion implantation, 13 ion beam mixing 14 ), mechanical cold working (ball milling, 15 cold rolling, 16 pressure 17 ) and solid-state reaction (multilayers, 18 single-source decomposition 19,20 ). Most of the works are devoted to the synthesis and study of metastable alloys in the form of thin films.…”
