Experience
05/2007-Present Graduate Research Assistant, SDSM&T
Cold spray deposited MMC brake rotors for Formula SAE race car.
o Blended 2024 Al with SiC in different ratios to determine impact on wear resistance
o Conducted wear resistance tests as per ASTM G65, the Al MMC coating performed better than the existing stainless steel rotors.
Investigated cold spraying nickel to improve the weldabilty of cast iron, for friction stir weld crack repair (Cummins)
o Investigated various spray parameters to optimize the nickel coating.
o Investigated spraying in machined slots to improve friction stir weldability
Deposited ultra fine Yttria stabilized Zirconia particles onto stainless steel substrate for PNNL
o Designed and built powder feeder
o Built aerodynamic focusing nozzle
o Successfully deposited 5 micron thick layer of YSZ onto SS.
Collaborated on new cold spray design that successfully deposited 300 nm copper powders, modeling suggests that smaller particles can be deposited.
o Awarded provisional patent application
Deposited polyethylene powder on 7075 substrate using cold spray
o Developed prototype nozzle from fishing rod and 308 practice shell
o Learned about electrolysis nickel coating, as the specimens had to be plated prior to sectioning to avoid edge rounding defects.
Determined feasibility of using cold spray process to stiffen light weight structures
o Worked with the SAE AeroDesign team to show that cold spray could be used in the construction of a lightweight airframe.
Investigated the feasibility of using the cold spray process in the repair of aging aircraft, and presented the findings to the Air Logistics Commands (Ogden, Tinker, Warner Robins).
o Helped develop cold spray as a chafing prevention coating on hydraulic tubing. Cold sprayed tubes are currently being flight tested on the B1 Bomber.
o Investigated using cold spray to repair fatigue cracks in a KC1 Stratotanker ruddervator
fitting, a FSW was selected over cold spray.
05/2006-09/2006 Undergraduate Research Assistant, SDSM&T
Investigated the parameters required to laser deposit a wear resistant coating on the leading edge of Toro lawn mower blades.
o Learned how to perform wear tests according to ASTM G65
Investigated the parameters required to laser deposit a wear resistant coating on glass forming plungers
Demonstrated the laser deposition process to participants in the Youth Engineering Adventure (YEA) program.
o Explained and demonstrated the Laser Engineered Near Net Shaping (LENS) process.
o Developed a program to deposit YEA key chains that we gave to the participants.

Thesis
FSSW of Mg-AL with a Cold Sprayed Interlayer
The friction stir welding process is a solid state joining process that has shown much promise in joining hard to weld materials. However, when joining Mg to Al brittle intermetallic compounds form that reduces the lap shear strength. To improve the lap shear strength the cold spray process was used to deposit various interlayer’s onto the aluminum substrates. The welds made with an interlayer were only slightly better than welds made without an interlayer.
Senior Design
Friction Stir Welded Engine Cradle
Developed a friction stir welded aluminum engine cradle for the Formula SAE mini Indy Car. To aid in manufacturability the design of the engine cradle had to be changed from the typical round tubing that was TIG welded to square tubing. The design was also changed from 4340 steel to 6061 aluminum.
