Title: The Innovations of Sergej-Tomislay Buljan
Introduction
Sergej-Tomislay Buljan is an accomplished inventor based in Acton, MA (US). He has made significant contributions to the field of materials science, particularly in the development of advanced ceramic-metal composites. His innovative work has led to the creation of a patented technology that enhances the performance of cutting tools.
Latest Patents
Buljan holds a patent for "Reinforced alumina ceramic-metal bodies." This invention describes a fully dense ceramic-metal body composed of approximately 40-68 volume percent (v/o) alpha-alumina, 10-30 v/o of a granular, hard refractory carbide, nitride, or boride, and 20-40 v/o silicon carbide platelets or elongated grains. Additionally, the body includes about 2-10 v/o of a dispersed metal phase that combines nickel (Ni) and aluminum (Al), primarily segregated at the microstructure's triple points. The preferred metal phase contains a substantial amount of the Ni3Al ordered crystal structure. This innovative body is produced by densifying a mixture of hard phase components and metal components, specifically using Ni powder and Al powder. The resulting body is particularly effective as a cutting tool for machining nickel superalloys or cast iron at high speeds and feed rates.
