Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Oxidation and Hot Corrosion of Superalloys

Superalloys 1984 (Fifth International Symposium), 1984
The oxidation, mixed gas corrosion and hot corrosion of nickel-, cobaltand iron-base superalloys at temperatures above about 6OOC are examined. It is shown that the superalloys develop resistance to corrosion by forming either alumina or chromia scales upon their surfaces.
