Title: Innovations by Jyoti P Chakraverty
Introduction
Jyoti P Chakraverty is an accomplished inventor based in Wooster, OH (US). She has made significant contributions to the field of materials science, particularly in the development of ceramic articles and transformation-toughened materials. With a total of 2 patents, her work showcases innovative approaches to enhancing material properties.
Latest Patents
One of her latest patents focuses on the injection molding of ceramic articles using aqueous-based thermoplastic. In this invention, polyvinyl alcohol copolymers are utilized as a binder in an aqueous ceramic particle slurry for injection molding green ceramic bodies. The slurry is dried to form a coated powder, which is then heated and injection molded into a desired shape. The molded shape is subsequently fired to remove the binder, resulting in a dense ceramic part that does not exhibit any knit lines from the injection molding process.
Another notable patent addresses the non-machining surface strengthening of transformation-toughened materials. This method involves grit blasting the surface of transformation-toughened zirconia bodies with materials such as alumina or silicon carbide. The grit blasting process can lead to flexural strength increases of at least about 10-20% compared to the body prior to blasting. This innovative method provides strength increases that are comparable to or better than those achieved through surface grinding and can be applied to a wider variety of body shapes.
