Software development for modeling irregular fine protrusions formed by sputter etching.

Abstract

Irregular fine protrusions formed on the surface of a mechanical part through biomimetic technology can enhance the part's properties, including tribology, self-cleaning, and light absorption. However, underlying principles for the formation of fine protrusions according to the requirements of their shapes, sizes, and material distributions have not been studied sufficiently. This paper presents the software development for modeling irregular fine protrusions, which is essential for the simulation, experimentation, and analysis of fine protrusions formed by sputter etching.
