Pulse Reverse Current Electrodeposited Tio2 Doped Ni-W Coating, Sydney Hughes Jan 2021

Pulse Reverse Current Electrodeposited Tio2 Doped Ni-W Coating, Sydney Hughes

Williams Honors College, Honors Research Projects

Nickel-Tungsten (Ni-W) coatings via the pulse reverse current method have been under development as a potential replacement for typical Chromium/Cadmium coatings. To increase the effectiveness of Ni-W as a coating, dopants have been tested to decrease microcracks and pores and increase overall tribological performance. Previous research by Timken Engineered Surfaces Laboratory showed that Ni-W doped with TiO2 nanoparticles had a positive effect on coating performance. The purpose of this study was to determine the ideal solution parameters (i.e. TiO2 concentration, pH) to maximize the benefit of the dopant when samples are subjected to tribological testing. Here, solutions of …


Jominy Hardenability Tester Redesign, Dennis Kopacz, Shadoe Beatty, Thomas Benenati, Jared Mclean, Matthew Yokosuk Jan 2021

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.


Automated Control System For The Remote-Controlled Torch Positioner, Christopher Ferguson, Anna Abate, Kyle Cramer, Alex Sabitsch, Jacob Stefanko Jan 2021

Automated Control System For The Remote-Controlled Torch Positioner, Christopher Ferguson, Anna Abate, Kyle Cramer, Alex Sabitsch, Jacob Stefanko

Williams Honors College, Honors Research Projects

The goal of this project is to design and implement a controls system for Dr. Morscher’s burner rig. The rig serves to simulate jet turbine conditions and test how materials, specifically ceramic matrix composites, react under high temperatures and stresses. Currently, the location of the torch relies solely on manual adjustments and has no automated control system. The improved design will automatically adjust the torch position based on the desired temperature of the sample being tested, therefore maintaining a steady environment for the sample. The current method of manual adjustments for regulating temperature is a crude solution that does not …


Design And Analysis Of One-Piece 10” Carbon Fiber Wheels For Zips Racing Zr20 Formula Sae Racecar, Patrick Kruse, Henry J. Wathen, Jordan J. Hyde, Nicholas D. Dobben, Jordan D. Blake Jan 2021

Reducing the weight of a vehicle in racing can substantially improve the vehicle dynamics and general performance capabilities. More specifically, the reduction of the unsprung corner weight can provide noticeable performance gains in handling and responsiveness, leading to a quicker, more agile car due to a lower yawing moment of inertia. Unsprung weight reduction also improves the car’s ability to maintain contact between the tires and the road surface for a more consistent grip. In this project we identified the loads that act on the wheel rims according to the data collected from the sensors in the car’s suspension, and …
