Abstract
This thesis demonstrated that the use of the Reduction Expansion Synthesis manufacturing process can be applied to cermet or metal matrix composite materials. This could potentially have a significant impact in the aerospace field because cermets and metal matrix composites have several desirable thermal resistance qualities. The Reduction Expansion Synthesis process was utilized on several different mixture ratios of nickel, nickel oxide, and ceramic powder. The various products created consisted of solid parts and films. These products were analyzed and compared utilizing methods such as scanning electron microscopy, Vickers hardness testing, energy dispersive spectroscopy, and light reflection analysis. It was found that 1% silica mixtures would produce the most effective cermet parts and that these mixtures can be applied to films on several metal substrates. These products have the potential to be useful for cermet coatings, which can be used to absorb high amounts of solar radiation and retain infrared radiation for use in a heat engine or for heat-resistant, ductile aerospace structural and electrical components.
