 This study proposes a new method for creating a volcanic ash-resistant coating for aircraft engine components. The coating is based on a biomimetic structure inspired by the lotus leaf, which has been shown to repel water droplets. This structure is then applied to a ceramic material and used to create a volcanic ash-resistant coating. The coating is able to resist the melting of volcanic ash, which could otherwise cause damage to the engine. This article was authored by Chen Guo, Wenjie Song, Lei Guo, and others.
