A novel surface treatment, laser assisted ultrasonic nanocrystal surface modification (LA-UNSM), has proved effective in increasing surface hardness, and fatigue life. The objective of this research is to determine the effectiveness of this process on components created with additive manufacturing. To accomplish this, we investigated the effectiveness of LA-UNSM treatment on aluminum, a common 3d printed metal, and the effectiveness of LA-UNSM processing on 3d printed titanium. We first conducted our own literature review to assess the practicality of using this same treatment on aluminum. We then treated traditionally manufactured aluminum at varying levels of laser intensity to determine if …

Our project is Redesigning a Hardenability Tester. The goal of this project is to figure out how to incorporate an intensive quenching system to the current design from last years group. An intensive quench is a new system that is safer to harden steel and it hardens steel more effectively than other quenching processes. This will be achieved through testing the initial design to make sure it is able to run. After that as a group we will take this system through a design process to introduce a safe process of intensive quenching to the tester.
