Diagnostics of the PEO-coating growth on a zirconium alloy by the acoustic spectrum [PDF]

EPJ Web of Conferences
Plasma-electrolytic oxidation is accompanied by microdischarges, which determine the main mechanism of coating growth. These microdischarges, along with electrolyte boiling, generate acoustic vibrations that are closely related to the coating growth ...

Plasma electrolytic oxidation of Titanium Aluminides

IOP Conference Series: Materials Science and Engineering, 2016
Due to their outstanding specific mechanical and high-temperature properties, titanium aluminides exhibit a high potential for lightweight components exposed to high temperatures. However, their application is limited through their low wear resistance and the increasing high-temperature oxidation starting from about 750 °C.
