Title: The Innovative Contributions of Nancy R. Brown
Introduction
Nancy R. Brown is a distinguished inventor based in Christiansburg, Virginia. She holds a total of six patents, showcasing her significant contributions to the field of materials science and engineering. Her work primarily focuses on the development of advanced coatings for ceramics, which have applications in various industries.
Latest Patents
Among her latest patents, Nancy has developed a magnesium doped β-aluminum titanate thin film coating. This innovative coating, represented as Mg.sub.x Al.sub.2-2x Ti.sub.1+x O.sub.5 (x ≤ 0.2), is designed for both dense and porous substrates, such as SiC and Si.sub.3 N.sub.4. The coating is created using a chemical solution processing method that involves the hydrolysis and condensation of magnesium, aluminum, and titanium precursors. The optimal conditions for achieving crack-free coatings include solution viscosities ranging from 1.0 to 6.2 cP, pH values between 1 and 4.5, molar ratios of 1.5 to 10, and dip coating withdrawal rates of 2.2 to 8.0 cm/min. The conversion of the amorphous coating to its crystalline form is accomplished through a series of calcination processes below 450°C, followed by a final heat treatment above 1000°C for ten hours.
Additionally, she has developed a sol-gel β-aluminum titanate thin film coating, represented as β-Al.sub.2 TiO.sub.5. This coating is also intended for dense and porous ceramics, utilizing a similar chemical solution processing method involving aluminum tri-sec butoxide and titanium butoxide. The parameters for achieving crack-free β-Al.sub.2 TiO.sub.5 include the same solution viscosities, pH values, molar ratios, and withdrawal rates as her magnesium doped coating. The transformation from amorphous to crystalline form is achieved through calcination below 450°C and a final heat treatment at 1300°C for ten hours.
