The Effects Of Layer Thickness On Dry-Sliding Wear Of Binder Jet Additively Manufactured Stainless Steel And Bronze Composite, Cody Ingenthron
The Effects Of Layer Thickness On Dry-Sliding Wear Of Binder Jet Additively Manufactured Stainless Steel And Bronze Composite, Cody Ingenthron
All Graduate Theses, Dissertations, and Other Capstone Projects
Pin on disk wear testing was used to compare additively manufactured binder jet metal matrix composites. The process parameters were changed. The layer thickness and applied forces were varied for the experimental study. Three different layer thicknesses used were, 50μm, 100μm, and 200μm. The pin used was a 420 stainless pin. The wear characteristics of the disk were examined using pin-on-disc method. The material tested was a composite of 420 stainless steel, and 90-10 bronze. Samples were weighed before, during, and after the test to determine differences in mass. Wear tracks were examined using a Scanning Electron Microscope. The results …
Thermal Conductivity Of Alumina And Silica Nanofluids, Julian Bernal Castellanos
Thermal Conductivity Of Alumina And Silica Nanofluids, Julian Bernal Castellanos
All Graduate Theses, Dissertations, and Other Capstone Projects
This thesis studies the effects of the base fluid, particle type/size, and volumetric concentration on the thermal conductivity of Alumina and Silica nanofluids. The effects of base fluid were observed by preparing samples using ethylene glycol (EG), water, and mixtures of EG/water as the base fluid and Al2O3 (10 nm) nanoparticles. The particles type/size and volumetric concentration effects were tested by preparing samples of nanofluids using Al2O3 (10nm), Al2O3 (150nm), SiO2 (15 nm), and SiO2 (80 nm) nanoparticles and ionized water as base fluid at different volumetric concentrations. All samples were mixed using a sonicator for 30 minutes and a …
The Effects Of Low-Level Ethanol Blends In 4-Stroke Small Non-Road Engines, Chris Reek
The Effects Of Low-Level Ethanol Blends In 4-Stroke Small Non-Road Engines, Chris Reek
All Graduate Theses, Dissertations, and Other Capstone Projects
Small Non-Road Engines (SNRE's) abound in numbers and are used daily by consumers and businesses alike. Considering the atmosphere of change looming in the air regarding alternative fuels, this particular engine classification will also be affected by any change in standardization of fuels. This body of research attempts to address possible ways SNRE's can change their operational characteristics after being fueled by specific yet differing fuels. These characteristics will be contrasted against blends of ethanol with gasoline, from 0% ethanol to 20% ethanol, run on test engines to determine patterns, if any, of these characteristics. Topics include: materials compatibility, engine …
