Microstructure and hydrogen impermeability of titanium nitride thin films deposited by direct current reactive magnetron sputtering
TL;DR: In this article, the influence of N2 flow rate and cathode current on grain size, crystal orientation and chemical state of the TiNx thin films was studied, and it was found that when N2 was increased from 5 to 10 and 15 sccm while cathode currents remained at 0.5 A, the grain size and atomic ratio of N/Ti decreased, and the strongest diffraction peak transforms from (111) to (200) plane.

Taoyuan Ouyang,Xuanwei Fang,Ying Zhang,Dawei Liu,Yan Wang,Shuaijie Feng,Tong Zhou,Shuizhou Cai,Jingpin Suo +8 more
TL;DR: In this paper, the SiC-self-healing coating, named the SAZ coating, was prepared by air plasma spray (APS) technique on the top of the classic bilayer TBC (YSZ TBC), which consist of the bond coating (BC) and the YSZ coating.

Effect of TiC self-healing coatings on the cyclic oxidation resistance and lifetime of thermal barrier coatings
Taoyuan Ouyang,Jinyang Wu,Muhammad Yasir,Tong Zhou,Xuanwei Fang,Yan Wang,Dawei Liu,Jingpin Suo +7 more
TL;DR: In this paper, a self-healing thermal barrier coatings (TBC) is proposed to suppress the growth of detrimental oxides by the formation of a low-porosity selfhealing layer at the top coat (TC)/bond coat (BC) interface.
