With a total of 5 patents to his name, Bakul's work has advanced the capabilities of cutting tools and other applications requiring high durability.
Latest Patents
Bakul's latest patents include a polycrystalline superhard material and a method for producing it. The proposed polycrystalline superhard material consists of sintered particles of cubic boron nitride, which are coated with a crystalline compound. This compound binds the particles together, enhancing the material's mechanical properties. The innovative production method involves placing cubic boron nitride particles in a gas flow containing carbon, allowing for a carbon layer to form on the particles. The resulting material exhibits superior durability, with cutters made from it lasting 2-5 times longer than those made from traditional cubic boron nitride materials.
Another notable patent is the method of making superhard articles. This method involves placing a mixture of powdered hard-alloy matrix material and diamond grains into a hard-alloy envelope. The envelope is designed to be significantly thicker than the space between the diamond grains, ensuring effective sintering without external mechanical loads. This innovative approach contributes to the creation of highly durable superhard articles.
