Development of Cold-sprayed Boron Carbide Metal Matrix Composite Coatings for Wear Resistance Applications
DownloadSpring 2017
Low-pressure cold spraying was used to fabricate boron carbide-based metal matrix composite coatings for wear resistance applications. Titanium carbide and tungsten carbide-based metal matrix composite coatings were also evaluated to allow for comparison. Powder blends containing 50, 75, and 92...

Fabrication of WC-based Metal Matrix Composite Coatings via Low-pressure Cold Spraying for Enhanced Surface Properties
DownloadFall 2013
A low-cost, low-pressure cold spray unit was used to fabricate tungsten carbide (WC)-based metal matrix composite (MMC) coatings. A variety of coatings were fabricated and characterized. Scanning electron microscopy (SEM), coupled with image analysis, Vickers micro-hardness, and X-ray diffraction...

Spring 2022
This thesis focuses on the manufacturing of high carbide content wear-resistant parts by extrusion- based Additive Manufacturing (AM) based on the principles of Powder Metallurgy (PM). A new manufacturing technique, termed Fused Filament Fabrication of Cermets (FFFC) is presented. First, particle...

Microstructural Analysis of Ni-WC Metal Matrix Composites Deposited Using Plasma Transferred Arc Additive Manufacturing
DownloadFall 2023
The objective of this thesis is to examine how the composition and solidification rate influences the thermal degradation of WC and the resulting microstructure of WC-Ni metal matrix composites (MMCs) deposited using plasma transferred arc additive manufacturing (PTA-AM). Scanning electron...

Preliminary geometrical and microstructural characterization of WC-reinforced NiCrBSi matrix composites fabricated by plasma transferred arc additive manufacturing through Taguchi-based experimentation
Download2021-01-01
Mercado Rojas, J.G., Ghasri-Khouzani, M., Wolfe, T., Fleck, B.A., Henein, H., Qureshi, A.J.
Metal matrix composites enhance the wear and corrosion properties of components in heavy-duty industries. This work reports the preliminary effects of process parameters such as current, linear speed, powder flow rate, nozzle angle, and powder, shield and center gases at the macro-scale and...

Thermally Sprayed Coatings as Resistive Heating Systems for Wind Turbine Blades and Airfoils
DownloadSpring 2023
Accumulation of ice on the surface of wind turbine blades and aircraft wings in cold environments causes serious issues such as decrease in performance and efficiency. Ice accretion alters the geometrical profile and aerodynamic performance of the surface and increases the weight of the original...
