Comparative Study on Wear Behaviors of Monolayer and Heterogeneous Multilayer Ta Coatings in Atmospheric and SBF Environments

Abstract: Monolayer Ta and multilayer Ti/Zr/Ta and Zr/Ti/Ta coatings were prepared by magnetron sputtering on TC4 substrates to improve the surface friction and wear properties in a simulated body fluid (SBF) environment and an atmospheric environment. Optical microscopy, scanning electron microscopy, laser scanning confocal microscopy and nano scratch testing were employed to establish the structure-property-environment relationships. By controlling the preparation parameters, the outermost layer of all three samples w… Show more

“…It is worth noting that the track depth on the Ta/Ti/Zr/Ta coating increased, which could be attributed to the weak adhesion strength of the coatings to the substrate under high normal load. This might have been caused by the poor adhesion of the multiple layers, and because each layer had a smaller thickness [36]. Moreover, Figure 7d presents the wear rate of the different samples based on the wear track profiles; the descending order of the wear rate is as follows: TC4 > Ta/Ti/Zr/Ta > Ta.…”

“…Moreover, due to the high specific fracture toughness, good medium and low temperature toughness and high melting point, titanium alloys are also extensively used in the manufacturing of various accessories of aero-engine casings, such as cups, double hinges, anti-icing shells and afterburner impellers of fuel systems, etc. [3,4]. Titanium alloy has been widely used in ships, metallurgical equipment, chemical machinery and other fields.…”
