Study of the droplet transition from Cassie to Wenzel state on laser-modified metal surfaces

Abstract

The paper presents the experimental study of the influence of laser radiation on the texture formation on aluminum alloy, the droplet transition from Cassie to Wenzel state, as well as the main geometric characteristics of a droplet (contact angle, droplet diameter and height). It was found that laser methods for changing the characteristics and texture of metal surfaces are a modern, flexible tool that makes it possible to achieve unique results in controlling the properties of metal surfaces.
