Data on the early oxidation of SiO2-coated pure Ti and bulk Ti5Si3 at 800 °C

Abstract

Oxidation of pure Ti sputtered with a 250 nm layer of amorphous SiO2 and bulk Ti5Si3 was conducted at 800 °C for 2 or 32 h in a 1 standard cubic centimeter per minute (SCCM) O2/4 SCCM Ar environment (approximately pO2 = 0.2 atm/20.3 kPa). Specimens were characterized using transmission electron microscopy, scanning transmission electron microscopy, and energy dispersive spectroscopy. The data in this article accompanies research article “Early oxidation behavior of Si-coated titanium” [1], which contains further discussion. The data for this article is hosted at the Materials Commons data repository and is available for download at https://materialscommons.org/mcapp/#/data/dataset/b8bc8038-a735-4cb9-9a9e-a0fb912b248c.

Protection of titanium alloys against high temperature oxidation during closed-die forging: Structural analysis of the boro-silicate glass coating/Ti-6Al-4V alloy interfacial region by correlative imaging

“…Analogously to Ti 2 O 3 , the dispersed state of TiB 2 would be due to its partial dissolution within the glass network. Formation of Ti 5 Si 3 has been strongly suggested during the interaction of Ti with silicon-containing coatings (Si, SiO 2 , glass, ...) in previous works [8,41,42]. The presence of other silicides was also sometimes suggested, see reference [41], and references herein.…”

Review of Research Progress on Mo–Si–B Alloys

“…Their study showed that the volume fraction of Mo 3 Si in the sample decreased with increasing Ti content and even disappeared completely in the 30Mo-40Ti-20Si-10B alloy with a phase composition of Mo ss + Mo 5 SiB 2 + Ti 5 Si 3 . Based on previous research findings, monolithic Ti 5 Si 3 demonstrates exceptional resistance to oxidation in the air up to 1250 • C [71][72][73][74]. As the unsatisfactory Mo 3 Si phase gradually disappeared and the content of the Ti 5 Si 3 phase increased, the alloy oxidation resistance at 800 • C was improved.…”
