Biomimetic teakwood structured environmental barrier coating

The core message of the article is that researchers have developed an innovative technology in plasma spraying-physical vapor deposition known as alternating vapor/liquid phase deposition.

By adjusting the arc current, researchers can finely control the evaporation and deposition of SiO₂, and through a heat treatment process, achieve in-situ reactions that optimize the composition, structure, and nanoscale dimensions of the coating, creating an orderly arranged multilayered teak-like biomimetic structure within it, notes a press release from EurekAlert. They have conducted an in-depth analysis of the complex deposition mechanisms involved in this process. This new teak-like biomimetic structure coating is expected to significantly enhance its mechanical properties and corrosion resistance, providing an innovative coating protection strategy for high-temperature applications in the field of gas turbine engines.

The team published their work in Journal of Advanced Ceramics.
