Wetting And Reactivity Of Active Metal Braze Alloys On Tungsten Carbide, Hayden Peck, Alan Meier, Ph.D.
Wetting And Reactivity Of Active Metal Braze Alloys On Tungsten Carbide, Hayden Peck, Alan Meier, Ph.D.
2014 Undergraduate Research
Background
Tungsten carbide is useful because of its hardness and strength. Joining of dissimilar materials especially non-metallic materials is very challenging. Active metals such as titanium can be added to a ductile filler metals such as copper to get wetting via a reduction reaction.
Conclusions
All alloy conditions wet the tungsten carbide/cobalt substrates. Two different interfacial reaction types were observed: dissolution and reduction reactions. An important issue has been identified: the braze interface reactions change the chemistry of the braze alloy which change the interaction between the braze alloy and the other material substrate.

Electrospinning is a widely applicable technique that generates non-woven fibers in the micro and nano range. In this project two of its applications are highlighted namely filtration media and enhancement of wettability. The first project demonstrates that electrospinning can be used to produce new fiber filtration media with controlled microstructure. The bimodal and unimodal orthogonal and random filters were made and characterized against their filtration efficiency and pressure drop. Figure of Merit (FOM) was also calculated and discussed. It is shown that the FOM increases when the electrospun fibers are arranged into alternating layers of aligned course and fine fibers. …
