Formation kinetics of multi-layered interfacial zone between γ-TiAl and glass–ceramic coatings via interfacial reactions at 1000 °C
Source abstract
Abstract
Abstract Glass–ceramic coatings are investigated for high temperature protection of γ-TiAl. This investigation focuses on the interfacial reactions between γ-TiAl and a glass–ceramic coating at 1000 °C in air by means of transmission/scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction. A thin interfacial zone of multilayered glass/Ti 5 Si 3 /α-Al 2 O 3 /Ti 3 Al at the interface was observed after oxidation for several hours. Both the growth of Ti 5 Si 3 and α-Al 2 O 3 layers obeyed parabolic rules, while the thickness of the Ti 3 Al layer increased first and then decreased. The mechanism for formation kinetics of the interfacial zone was discussed.
