SPU-8: COMSOL-generated Weld Heat Transfer Models For Automation of Infrared Thermography Non-destructive Testing (IR-TNDT) Image Analysis: Savannah Horowitz1; Brittani Maskley1; Michele Manuel1; 1University of Florida
Defect detection methods in welding can be complex, time-consuming, and costly. As more cost-efficient processes are implemented, the depth of defect detection can be diminished. Infrared Thermography Non-Destructive Testing (IR-TNDT) is a promising time- and cost-efficient method for subsurface weld defect detection. IR-TNDT collects thermal data of imaged targets and is currently used in defect detection applications, including steel pipe corrosion and electrical component flaws. Investigations exploring IR-TNDT on subsurface weld defects have shown promise. However, there is a need for complimentary fast and precise image analysis to implement this technique into the industry and in the field. This study aims to develop weld heat transfer models using the multi-physics COMSOL software platform and then utilize these models to detect weld defects in IR images.
SPU-9:Mechanochemistry for Creation of Functional Surface Treatments: Jennifer Johnson1; William Cross1; James Tomich1; Grant Crawford1; Jon Kellar1; 1South Dakota School of Mines and Technology
This research explores mechanochemistry to create functional surface treatments. A planetary centrifugal mixer was used to modify fluorite (CaF2) and BAM particles (Aluminum Magnesium Boride, Al3Mg3B56) surfaces. BAM and fluorite particles were treated with oleic acid to increase hydrophobicity. The particles were evaluated using Fourier transform infrared spectroscopy (FTIR) and contact angle goniometry to determine the effectiveness of mixing and possible reactivity. Contact angle measurements revealed that the fluorite particles turned from hydrophilic to hydrophobic with a contact angle of 150° when treated with low amounts of oleic acid. FTIR spectroscopy revealed a chemisorbed calcium oleate on fluorite while oleic acid with boric acid present for BAM. The mechanochemical process is successful in transforming surface properties without the use of water or heat and holds promise for surface engineering in areas of mineral processing, and additive manufacturing.
