Abstract
This work leverages high throughput, highly tunable laser manufacturing capabilities for the inverse design of anti-corrosion surfaces. Laser processing of a material can induce a variety of surface chemistry and topology changes that can prevent a corrosion reaction from taking place. The simplest approach to preventing corrosion is the removal of moisture, or the electrolyte that catalyzes the corrosion reaction. To analyze potential for moisture removal, each laser processed surface generated in this work was analyzed for its contact angle hysteresis, giving a dynamic look at how water interacts with each surface. Contact angle hysteresis is obtained through viewing a droplet on a vibrating surface, where the angles are measured as the surface moves below the droplet. The systems developed allow for the manufacture and analysis of a unique new surface every few seconds, with a dataset of over 40,000 surfaces created.

Jake Carter is a Mechanical Engineering PhD Candidate in the Laser Technologies group at Lawrence Berkeley National Laboratory and UC Berkeley, with a concentration in Energy Science and Technology. His research focus is on high throughput laser surface processing for multifunctional performance. More specifically, his work develops diagnostic tools that can analyze surface performance at the rate they can be processed by laser systems. The combination of laser processing and these tools allow for the optimization of surface properties across different applications, allowing high performance in anti-corrosion, anti-icing, optical properties, hardness, and durability through clean laser processing techniques. Jake’s previous research included the development of optical hyperbolic metamaterials at the Air Force Research Laboratory, and heat transfer characterization using optical techniques at the interfacial transport lab at the University of Central Florida.
